Answer:

The number is 10

Step-by-step explanation:

Let the number be x.

four thirds times = 4/3

According to the statement:

four thrids times the sum of a number and 8 is 24

4/3 *(x+8)= 24

Move  3 to the R.H.S and Multiply 4 with the parenthesis.

4x+32=24*3

4x+32=72

Move constant to the R.H.S

4x=72-32

4x=40

Divide both the terms by 4

4x/4=40/4

x=10

Therefore the number is 10....

Final answer:

To solve the equation, which is four thirds times the sum of a number and 8 equals 24, we isolate the variable by dividing by four thirds and subtracting 8 from both sides, resulting in the number being 10.

Explanation:

The student's question is asking to solve an algebraic equation. Specifically, the equation is: four thirds times the sum of a number and 8 equals 24. To find the number, represented by a variable, we'll denote it as x and translate the statement into the following equation: (4/3) × (x + 8) = 24.

First, we need to divide both sides of the equation by 4/3 to isolate the sum on one side:

(x + 8) = 24 × (3/4)

(x + 8) = 18

Now, subtract 8 from both sides to solve for x:

x = 18 - 8

x = 10

The final answer is that the number is 10. This is obtained through a step-by-step explanation solving the initial equation.

Answer:

(-1,-5)

Step-by-step explanation:

So we have the system:

y=3x-2

x-y=4.

We are asked to use substitution. Luckily, it is already setup for this because one of the equations has one of the variables solved for, namely the y=3x-2 equation.  We are going to insert y=3x-2 into x-y=4 and solve for x.

x-y=4  (with y=(3x-2) ):

x-(3x-2)=4

Distribute:

x-3x+2=4

Combine like terms:

-2x+2=4

Subtract 2 on both sides:

-2x    =2

Divide both sides by -2:

 x     =-1

Now if y=3x-2 and x=-1, then y=3(-1)-2=-3-2=-5.

So the solution is (-1,-5).

Answer:

○ D. 116°

Step-by-step explanation:

Think of the Unit Circle. You know that half of 360° is 180°, and that angle has a measure of 58°, so you do this:

-58° + 180° = 122°

Now, that chord of the circle drags it a bit by a few units, so that will be approximately 116°.

Answer:

100 is the number which can be multiplied to eliminate the decimals....

Step-by-step explanation:

Given:

Which number can each term of the equation be multiplied by to eliminate the decimals before solving

5.6j – 0.12 = 4 + 1.1j

Solution:

Notice that the constants and the coefficients in this equation contains decimal. All the numbers are in decimal up to tenth place except 0.12 which has decimal up to hundredth place.

Therefore, if we want to eliminate the decimal from 0.12 we have to multiply it by 100.

Thus the given equation will be multiplied by 100 to eliminate decimal from the terms.

100(5.6j – 0.12 = 4 + 1.1j)

By multiplying the equation by 100 we get:

560j - 12 = 400 + 110j

Thus 100 is the number which can be multiplied to eliminate the decimals....

Answer:

100

Step-by-step explanation:

Well, to answer this question, you have to find the number/coefficient that has the most numbers after a decimal point (not including trailing zeros), and then use the rule 10^(numbers after the decimal point) to see how to eliminate the decimals. So, 2 digits, 10^2=100

Jesse should use kilograms to weigh the package for postage.

Jesse should use kilograms to weigh the package for postage. The books and documents in the box would likely weigh more than grams, so a larger unit of measurement is needed. Kilograms are a commonly used metric unit for measuring weight, and they are suitable for weighing the package accurately and determining the postage required.

Answer: The inverse is x/5

===============================================

How I got this answer:

The original function has 5x or 5*x, which reads out "five times x"

We have some unknown number x and we are multiplying it by 5. The inverse function undoes everything the original f(x) function does. Since the opposite of multiplicaiton is division, this means our answer involves dividing by 5.

--------

Here is a more algebraic explanation

f(x) = 5x

y = 5x  .... replace f(x) with y

x = 5y

5y = x

y = x/5 .... divide both sides by 5 (to undo the multiplication)

g(x) = x/5 .... replace y with g(x)

here g(x) represents the inverse of f(x)

One useful property of inverses is that f( g(x) ) = g( f(x) ) = x

Answer:

2

Step-by-step explanation:

So I'm going to use vieta's formula.

Let u and v the zeros of the given quadratic in ax^2+bx+c form.

By vieta's formula:

1) u+v=-b/a

2) uv=c/a

We are also given not by the formula but by this problem:

3) u+v=uv

If we plug 1) and 2) into 3) we get:

-b/a=c/a

Multiply both sides by a:

-b=c

Here we have:

a=3

b=-(3k-2)

c=-(k-6)

So we are solving

-b=c for k:

3k-2=-(k-6)

Distribute:

3k-2=-k+6

Add k on both sides:

4k-2=6

Add 2 on both side:

4k=8

Divide both sides by 4:

k=2

Let's check:

[tex]3x^2-(3k-2)x-(k-6) \text{ with }k=2[/tex]:

[tex]3x^2-(3\cdot 2-2)x-(2-6)[/tex]

[tex]3x^2-4x+4[/tex]

I'm going to solve [tex]3x^2-4x+4=0[/tex] for x using the quadratic formula:

[tex]\frac{-b\pm \sqrt{b^2-4ac}}{2a}[/tex]

[tex]\frac{4\pm \sqrt{(-4)^2-4(3)(4)}}{2(3)}[/tex]

[tex]\frac{4\pm \sqrt{16-16(3)}}{6}[/tex]

[tex]\frac{4\pm \sqrt{16}\sqrt{1-(3)}}{6}[/tex]

[tex]\frac{4\pm 4\sqrt{-2}}{6}[/tex]

[tex]\frac{2\pm 2\sqrt{-2}}{3}[/tex]

[tex]\frac{2\pm 2i\sqrt{2}}{3}[/tex]

Let's see if uv=u+v holds.

[tex]uv=\frac{2+2i\sqrt{2}}{3} \cdot \frac{2-2i\sqrt{2}}{3}[/tex]

Keep in mind you are multiplying conjugates:

[tex]uv=\frac{1}{9}(4-4i^2(2))[/tex]

[tex]uv=\frac{1}{9}(4+4(2))[/tex]

[tex]uv=\frac{12}{9}=\frac{4}{3}[/tex]

Let's see what u+v is now:

[tex]u+v=\frac{2+2i\sqrt{2}}{3}+\frac{2-2i\sqrt{2}}{3}[/tex]

[tex]u+v=\frac{2}{3}+\frac{2}{3}=\frac{4}{3}[/tex]

We have confirmed uv=u+v for k=2.

Answer:

I prefer to express solutions to inequalities using interval notation. Both formats are are important but I think interval notation is easier to understand and represents better the solutions.

For example, if you have the following inequation:

x-2> 1

x>3

Therefore, the solution could be written either x>3 OR (3, +inf). But what happens if the solution to the system of equation is x>3 or x<-3? The solution can be easily written as: (-inf, -3) U  (3, inf) instead of 'x>3 or x<-3' which can be confusing.

Answer:

[tex]y = - 3.0625[/tex]

Step-by-step explanation:

The given parabola has equation:

[tex] \frac{1}{4} (y + 3) = {(x - 2)}^{2} [/tex]

Or

[tex]{(x - 2)}^{2} = \frac{1}{4} (y + 3)[/tex]

We compare this to

[tex] {(x - h)}^{2} = 4p(y - k)[/tex]

[tex] \implies \: 4p = \frac{1}{4} [/tex]

[tex]p = \frac{1}{4} \div 4[/tex]

[tex]p = \frac{1}{4} \times \frac{1}{4} [/tex]

[tex]p = \frac{1}{16} [/tex]

The vertex of this parabola is (2,-3)

The directrix is p units below the y-value of the vertex

[tex]y = - 3 - \frac{1}{16} = - 3.0625[/tex]

-30 is your answer.

~

Firstly, find the slope.

Let m = slope

m = (8 - 4)/(1 - 0)

m = 4/1

m = 4

Now use the point-slope formula.

y - y_1 = m(x - x_1)

Pick one of the given points. I will use the point (0, 4) but you can certainly use (1, 8) if you'd like.

We now plug and chug.

y - 4 = 4(x - 0)

y - 4 = 4x

y = 4x + 4

Replace y with f(x).

f(x) = 4x + 4

Did you follow?

Answer:

f(x) = 4 x (2)^x

Answer: 82%

Step-by-step explanation: Count the total number of marbles.

9+6+7+11=33 marbles in total.

We are trying to find the probability of NOT picking a blue marble. There are 6 blue marbles. Subtract the blue marbles from the total.

33-6=27

The probability of not picking a blue marble is 27/33. Divide the fraction.

27/33=0.82

Multiply by 100 to get the percent.

0.82 x 100 = 82%

There is an 82% chance of not picking a blue marble.

Answer:

21/2x^2+4x

Step-by-step explanation:

Answer:

2x-y = -4

Step-by-step explanation:

We can use the point slope form of a line to write the equation and then convert it to standard form

y-y1 = m(x-x1) where m is the slope and (x1,y1) is the point

y-2 =2(x--1)

y-2 =2(x+1)

y-2 =2x+2

The standard form is Ax +By =C

Subtract 2x from each side

-2x +y -2 =2x-2x+2

-2x+y-2 =2

Add 2 to each side

-2x+y -2+2 =2+2

-2x+y=4

The x term should be positive

Multiply by -1

2x-y = -4

[tex]4\sqrt{37} units[/tex] is the perimeter of square ABCD.

Step-by-step explanation:

Coordinates of square ABCD:

A = (3,4), B = (2,-2), C = (-4-1) , D = (-3,5)

Distance formula: [tex](x_1,y_1),(x_2,y_2)[/tex]

[tex]d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]

Distance of AB: A = (3,4), B = (2,-2)

[tex]AB=\sqrt{(2-3)^2+(-2-4)^2}[/tex]

[tex]AB=\sqrt{(-1)^2+(-6)^2}=\sqrt{37} units[/tex]

Given that the ABCD is square, then:

AB = BC = CD = DA

Perimeter of the square ABC = AB +BC + CD + DA

[tex] AB+ AB+ AB+ AB= 4AB=4\sqrt{37} units[/tex]

[tex]4\sqrt{37} units[/tex] is the perimeter of square ABCD.
