Answer is A On edgu

Answer:

y = - 2

Step-by-step explanation:

The equation of a horizontal line parallel to the x- axis is

y = c

where c is the value of the y- coordinates the line passes through.

The points (2, - 2) and (0, - 2) have the same y- coordinate and therefore lie on a horizontal line with equation

y = - 2

Answer:

No

Step-by-step explanation:

Given a function f(x)

For the function to be odd then f(- x) = - f(x)

f(- x) = 3(- x)² + (- x) = 3x² - x

- f(x) = - (3x² + x) = - 3x² - x

Since f(- x) ≠ - f(x) then f(x) is not an odd function

Answer:

19/24

Step-by-step explanation:

Since you are looking for the fraction he spend, you have to add 3/8 and 5/12 with one another. To do this you have to change those fractions to have the same denominators. so you multiply 3/8 by 3/3 to get 9/24 and you multiply 5/12 by 2/2 to get 10/24. You then add 9/24 with 10/24 to get 19/24. Since you cannot simplify this further, 19/24 is your answer.

Answer:

(6,6) only goes with Line 2

(3,4) goes with neither

(7,2) goes with both

Step-by-step explanation:

Ok to decide if a point is on a line you plug it in.  If you get the same thing on both sides, then that point is on that line.  If you don't get the same thing on both sides, then that point is not on that line.

Test (6,6) for -5x+6y=-23.

(x,y)=(6,6) gives us

-5x+6y=-23

-5(6)+6(6)=-23

-30+36=-23

6=-23

So (6,6) is not on -5x+6y=-23.

Test (6,6) for y=-4x+30

(x,y)=(6,6) give us

y=-4x+30

6=-4(6)+30

6=-24+30

6=6

So (6,6) is on y=-4x+30.

Test (3,4) for -5x+6y=-23.

(x,y)=(3,4) gives us

-5x+6y=-23

-5(3)+6(4)=-23

-15+24=-23

9=-23

So (3,4) is not on -5x+6y=-23.

Test (3,4) for y=-4x+30.

(x,y)=(3,4) gives us

y=-4x+30

4=-4(3)+30

4=-12+30

4=18

So (3,4) is not on y=-4x+30.

Test (7,2) for -5x+6y=-23.

(x,y)=(7,2) gives us

-5x+6y=-23

-5(7)+6(2)=-23

-35+12=-23

-23=-23

So (7,2) is on -5x+6u=-23.

Test (7,2) for y=-4x+30.

(x,y)=(7,2) gives us

y=-4x+30

2=-4(7)+30

2=-28+30

2=2

So (7,2) is on y=-4x+30

(x,y)  Line 1    Line 2     Both     Neither

(6,6)                  *

(3,4)                                                   *

(7,2)                                  *

(6,6) only goes with Line 2

Answer: Second Option

[tex]P (-1.17 <z <1.17) = 0.7580[/tex]

Step-by-step explanation:

The shaded area corresponds to the interval

[tex]-1.17 <z <1.17.[/tex]

By definition, for a standard normal distribution the area under the curve in the interval (b <z <h) is equal to:

[tex]P (b <z <h)[/tex]

So in this case we look for:

[tex]P (-1.17 <z <1.17)[/tex]

This is:

[tex]P (-1.17 <z <1.17) = P (z <1.17) - P (z <-1.17)[/tex]

Looking at the standard normal table we have to:

[tex]P (z <1.17) = 0.8790\\P (z <-1.17) = 0.1210[/tex]

So:

[tex]P (-1.17 <z <1.17) = 0.8790- 0.1210\\\\P (-1.17 <z <1.17) = 0.7580[/tex]

Answer:

-55/4

Step-by-step explanation:

-4 1/4 - (9 1/2)

Both the terms are given in whole fraction:

Change the terms into improper fraction

4*-4+1 = -17/4

2*9 + 1=19/2

Now,

-17/4 - 19/2

Now take the L.C.M of the denominator.

L.C.M of 4 and 2 is 4

Solve for numerator:

L.C.M (4) divided by denominator of first term will give quotient 1. Then 1 multiply by the numerator -17 will give us 1* -17 = -17

Then 4 divided by denominator of 2nd term will give us 2 as a quotient. Then quotient multiplied by numerator of 2nd term will give us 19*2 = 38

Therefore,

-17 - 38/4

= -55/4

The answer is -55/4....

The expression -4 1/4 - (9 1/2), is simplified to be expressed as -53/4

To simplify the expression -4 1/4 - (9 1/2), we need to convert the mixed numbers to improper fractions and perform the subtraction.

First, let's convert the mixed numbers to improper fractions:

-4 1/4 = -4 + 1/4 = -4 * 4/4 + 1/4 = -16/4 + 1/4 = -15/4

9 1/2 = 9 + 1/2 = 9 * 2/2 + 1/2 = 18/2 + 1/2 = 19/2

Now we can substitute these values back into the original expression:

-15/4 - 19/2

To subtract fractions, we need a common denominator. The least common multiple (LCM) of 4 and 2 is 4, so we can rewrite the fractions with a common denominator of 4:

-15/4 - 19/2 = -15/4 - 38/4

Now we can subtract the fractions:

-15/4 - 38/4 = (-15 - 38)/4 = -53/4

Therefore, the expression -4 1/4 - (9 1/2) simplifies to -53/4.

Step-by-step explanation:

The reason its Point D because its the only one that is the farest away from the rest of the points on the plot.

The reason why "Point D" would be the correct answer because the point is no where near the "trend" of the scatter plot.

When you look at the scatter plot, you would notice that there following a "trend" when the graph increases.

However, you would notice that point D is not really near there, therefore making it an outlier.

An outlier is pretty much something that is left out, and in this case, point D would be the outlier since it's left out of the typical growth of the scatter plot.

Answer:

111

Step-by-step explanation:

a1 = -12

a27 = 66

Now using the formula  an = a1+(n-1)d we will find the value of d

here n = 27

a1 = -12

a27 = 66

Now substitute the values in the formula:

a27 = -12+(27-1)d

66= -12+(26)d

66 = -12+26 * d

66+12 = 26d

78 = 26d

now divide both the sides by 26

78/26= 26d/26

3 = d

Now put all the values in the formula to find the 42 term

an = a1+(n-1)d

a42 = -12 +(42-1)*3

a42 = -12+41 *3

a42 = -12+123

a42 = 111

Therefore 42 term is 111....

Answer:

Assuming it is arithmetic, the 42nd term is 111.

Assuming it is geometric, the conclusion says it isn't geometric.

Step-by-step explanation:

Let's assume arithmetic first.

Arithmetic sequences are linear. They go up or down by the same number over and over.  This is called the common difference.

We are giving two points on our line (1,-12) and (27,66).

Let's find the point-slope form of this line.

To do this I will need the slope.  The slope is the change of y over the change of x.

So I'm going to line up the points and subtract vertically, then put 2nd difference over 1st difference.

(1  , -12)

-(27,66)

------------

-26   -78

The slope is -78/-26=78/26=3.  The slope is also the common difference.

I'm going to use point [tex](x_1,y_1)=(1,-12)[/tex] and [tex]m=3[/tex] in the point-slope form of a line:

[tex]y-y_1=m(x-x_1)[/tex]

[tex]y-(-12)=3(x-1)[/tex]

Distribute:

[tex]y+12=3x-3[/tex]

Subtract 12 on both sides:

[tex]y=3x-3-12[/tex]

[tex]y=3x-15[/tex]

So we want to know what y is when x=42.

[tex]y=3(42)-15[/tex]

[tex]y=126-15[/tex]

[tex]y=111[/tex]

So [tex]a_{42}=111[/tex] since the explicit form for this arithmetic sequence is

[tex]a_n=3n-15[/tex]

-----------------------------------------------------------------------------------------

Let's assume not the sequence is geometric. That means you can keep multiplying by the same number over and over to generate the terms given a term to start with.  That is called the common ratio.

The explicit form of a geometric sequence is [tex]a_n=a_1 \cdot r^{n-1}[/tex].

We are given [tex]a_1=-12[/tex]

so this means we have

[tex]a_n=-12 \cdot r^{n-1}[/tex].

We just need to find r, the common ratio.

If we divide 27th term by 1st term we get:

[tex]\frac{a_{27}}{a_1}=\frac{-12r^{27-1}}{-12r^{1-1}}=\frac{-12r^{26}}{-12}=r^{26}[/tex]

We are also given this ration should be equal to 66/-12.

So we have

[tex]r^{26}=\frac{66}{-12}[/tex].

[tex]r^{26}=-5.5[/tex]

So the given sequence is not geometric because we have an even powered r equaling a negative number.

Answer:

x= 3

y= 2

Step-by-step explanation:

The given equations are :

2x-5y = -4    equation 1

x +6y = 15    equation 2

We will multiply the equation:2 by 2

2(x+6y=15)

2x+12y=30   equation 3

Lets call this equation:3

Now we will use the elimination method:

Subtract equation 3 from equation 1:

2x-5y = -4

2x+12y=30

_________

   -17y = -34

y= -34/-17

y = 2

Now put the value of y in any equation:

We will use equation 1

2x-5y = -4

2x-5(2)= -4

2x-10= -4

Move the constant to the R.H.S

2x= -4+10

2x=6

Divide both the terms by 2

x= 3

Therefore the solution set is (x,y){(3,2)}....

We add 8 to both sides of the equation:

[tex]2x = 20 + 8\\2x = 28[/tex]

The officer saves $91.45 per month

~Step-by-step explanation~

Ok this is how I do fractions and its not very good, but it works.

First I divided 6400 by 5, 6, and 7, (I didn't do 3 because you can just multiply the answer to 6 by 2.) the reason I divided these is to see how much 1 part of their fraction is worth. So in total I got  1066.66 (irrational number) for insurance which means I got 2133.32 for his monthly living ( had to multiply by 2). For his car payment I got 1828.57 (I divided and then multiplied by 2) and for his rent I got 1280. I added these all together to get the total he spends each month which was 6308.55, and I subtracted that from 6400 to figure out that he puts $91.45 in his savings account

Answer:

The answer is R91.43.

Step-by-step explanation:

Monthly salary of the worker = R6400

The monthly expenses are 1/5 for rent that is [tex]\frac{1}{5}\times6400= 1280[/tex]

The car payment is 2/7 that is [tex]\frac{2}{7}\times6400= 1828.57[/tex]

The insurance is 1/6 that is [tex]\frac{1}{6}\times6400= 1066.67[/tex]

Few other monthly living expenses are 1/3 that is [tex]\frac{1}{3}\times6400= 2133.33[/tex]

We will total these values:

[tex]1280+1828.57+1066.67+2133.33=6308.57[/tex]

So, the amount that is saved per month = [tex]6400-6308.57=91.43[/tex]

The answer is R91.43.

Dotted linear inequality shaded below passes through (0, 4) & (4,3). Dotted parabolic inequality shaded above passes through points (negative 6,4), (negative 4, 0) & (negative 2, 4).

Hello! Let me help you to find the correct option to this problem. First of all, we have the following system of inequalities:

[tex]\left\{ \begin{array}{c}y< -\frac{1}{4}x+4\\y>(x+4)^{2}\end{array}\right.[/tex]

To solve this, let's write the following equations:

[tex]y=-\frac{1}{4}x+4[/tex]

This is a linear function written in slope-intercept form as [tex]y=mx+b[/tex]. So, the slope [tex]m=-\frac{1}{4}[/tex] and the y-intercept is [tex]b=4[/tex]. Since in the inequality we have the symbol < then the graph of the line must be dotted. To get the shaded region, let's take a point, say, [tex](0, 0)[/tex] and let's test whether the region is above or below the graph. So:

[tex]y< -\frac{1}{4}x+4 \\ \\ Let \ x=y=0 \\ \\ 0<-\frac{1}{4}(0)+4 \\ \\ 0<4 \ True![/tex]

Since the expression is true, then the region is the one including point [tex](0, 0)[/tex], that is, it's shaded below.

[tex]y=(x+4)^{2}[/tex]

This is a parabola that opens upward and whose vertex is [tex](-4,0)[/tex]. Since in the inequality we have the symbol > then the graph of the parabola must be dotted. Let's take the same point [tex](0, 0)[/tex] to test whether the region is above or below the graph. So:

[tex]y>(x+4)^{2} \\ \\ Let \ x=y=0 \\ \\ 0>(0+4)^2\\ \\ 0>16 \ False![/tex]

Since the expression is false, then the region is the one that doesn't include point [tex](0, 0)[/tex], that is, it's shaded above

____________________

[tex]y=-\frac{1}{4}x+4 \\ \\ \\ \bullet \ (0,4): \\ \\ y=-\frac{1}{4}(0)+4 \therefore y=4 \\ \\ \\ \bullet \ (4,3): \\ \\ y=-\frac{1}{4}(4)+4 \therefore y=3[/tex]

So the line passes through these two points.

[tex]y=(x+4)^2 \\ \\ \\ \bullet \ (-6,4): \\ \\ y=(-6+4)^2 \therefore y=(-2)^2 \therefore y=4 \\ \\ \\ \bullet \ (-4,0): \\ \\ y=(-4+4)^2 \therefore y=0 \\ \\ \\ \bullet \ (-2,4): \\ \\ y=(-2+4)^2 \therefore y=(2)^2 \therefore y=4[/tex]

So the line passes through these three points.

Finally, the shaded region is shown below.

Answer:

The equation of the line is y = -x + 1

Step-by-step explanation:

* Lets explain how to solve the problem

- The slope-intercept form of the equation is y = mx + c, where m is

 the slope of the line and c is the y-intercept

- To make this equation you need slope (m) and a point on the line to

 find the value of c

- The parallel lines have same slopes

* Lets solve the problem

- The line is parallel to the line y = -x - 5

∵ y = mx + c

∵ The slope of the line y = -x - 5 is the coefficient of x

∴ m = -1

∵ Parallel lines have same slopes

∴ The slope of the line is -1

∴ the equation of the line is y = -x + c

- To find c substitute x and y in the equation by the coordinates of

  any point lies on the line

∵ The line passes through point (3 , -2)

∵ y = -x + c

∴ -2 = -(3) + c

∴ -2 = -3 + c ⇒ add 3 for both sides

∴ c = 1

∴ The equation of the line is y = -x + 1

Answer:

B.

Step-by-step explanation:

So [tex]2x^2+5x+3[/tex] will have two factors if one factor in the form [tex](ax+b)[/tex] is given.

The other factor will also be in the form of [tex](cx+d)[/tex].

So we have

[tex](x+1)(cx+d)[/tex]:

Let's use foil.

First:  x(cx)=cx^2

Outer: x(d)=dx

Inner: 1(cx)=cx

Last: 1(d)=d

---------------------Adding like terms:

cx^2+(d+c)x+d

We are comparing this to:

2x^2+     5x+3

So we see that c=2 and d=3 where the other factor is cx+d=2x+3.

Also this works since c+d=5 (we know this because 2+3=5).

3x² - 2x + 5 ; will be a polynomial ⇒ answer A

Step-by-step explanation:

* Lets explain what is the polynomial

- A polynomial is an expression containing two or more algebraic terms.

- Polynomial is often the sum of some terms containing different powers

 of variables.  

- If you add or subtract polynomials, you get another polynomial.

- If you multiply polynomials, you get another polynomial.

* Lets solve the problem

∵ 5x² + 3x + 4 is polynomial

∵ 2x² + 5x - 1 is polynomial

- When we subtract them the answer will be polynomial

∵ (5x² + 3x + 4) - (2x² + 5x - 1)

- Open the second bracket by multiplying the negative sign by

  each term in the bracket

∵ -(2x²) = -2x²

∵ -(5x) = -5x

∵ -(-1) = 1

∴ (5x² + 3x + 4) - (2x² + 5x - 1) = 5x² + 3x + 4 - 2x² - 5x + 1

- Add the like terms

∴ (5x² - 2x²) = 3x²

∴ (3x - 5x) = -2x

∵ (4 + 1) = 5

∴ (5x² + 3x + 4) - (2x² + 5x - 1) = 3x² - 2x + 5

∴ 3x² - 2x + 5 is a polynomial

∴ (5x² + 3x + 4) - (2x² + 5x - 1) = 3x² - 2x + 5 ; will be a polynomial

Step-by-step explanation:

[tex]\sqrt[n]{a}=a^\frac{1}{n}\Rightarrow\sqrt[5]{x}=x^\frac{1}{5}\\\\\sqrt[5]{x}\cdot\sqrt[5]{x}\cdot\sqrt[5]{x}\cdot\sqrt[5]{x}=x^\frac{1}{5}\cdot x^\frac{1}{5}\cdot x^\frac{1}{5}\cdot x^\frac{1}{5}\qquad\text{use}\ a^n\cdot a^m=a^{n+m}\\\\=x^{\frac{1}{5}+\frac{1}{5}+\frac{1}{5}+\frac{1}{5}}=x^\frac{4}{5}[/tex]

Answer:

[tex]x^{\frac{4}{5}}[/tex]

Step-by-step explanation:

fifth root of x can be written in exponential for as:

[tex]x^\frac{1}{5}[/tex]

[tex]x^\frac{1}{5}[/tex] times  [tex]x^\frac{1}{5}[/tex] times  [tex]x^\frac{1}{5}[/tex] times  [tex]x^\frac{1}{5}[/tex]

WE apply exponential property to multiply it

a^m times a^n= a^{m+n}

[tex]x^\frac{1}{5}[/tex] times  [tex]x^\frac{1}{5}[/tex] times  [tex]x^\frac{1}{5}[/tex] times  [tex]x^\frac{1}{5}[/tex]

[tex]x^{\frac{1}{5} +\frac{1}{5}+\frac{1}{5}+\frac{1}{5}}[/tex]

The denominator of the fractions are same so we add the numerators

[tex]x^{\frac{4}{5}}[/tex]

Answer:

B

Step-by-step explanation:

Using the Sine Rule in ΔABC

[tex]\frac{a}{sinA}[/tex] = [tex]\frac{b}{sinB}[/tex] = [tex]\frac{c}{sinC}[/tex]

∠C = 180° - (82 + 58)° = 180° - 140° = 40°

Completing values in the above formula gives

[tex]\frac{a}{sin58}[/tex] = [tex]\frac{b}{sin82}[/tex] = [tex]\frac{8.4}{sin40}[/tex]

We require a pair of ratios which contain b and 3 known quantities, that is

[tex]\frac{b}{sin82}[/tex] = [tex]\frac{8.4}{sin40}[/tex]

OR

[tex]\frac{sin40}{8.4}[/tex] = [tex]\frac{sin82}{b}[/tex] → B

Answer:

B
