C. (x, y) -> (x - 4, x - 5)

D. (x, y) -> (x - 5, y - 4)​

Answer:

The correct option is D

Step-by-step explanation:

To find the solution of this problem firstly we will find the probability that some one is in the brass section and play trombone.

We will multiply the probability that a member is in the brass section which is 0.50 with the probability that a member plays trombone, given that he or she is in the brass section which is 0.36

= 0.50 * 0.36

=0.18

Therefore the probability that a randomly selected band member is in the brass section and plays trumpet is 0.18

Thus the correct option is D....

Answer:

8 is the only one that will work

Step-by-step explanation:

(f o g)(x)=f(g(x)).

So this means the x will first be plug into g.

So let's check your choices.

g(6)=1/(6-6)=1/0 so 6 is not in the domain of g which means it isn't in the domain of (f o g).

g(8)=1/(8-6)=1/2  so this is a number so 8 is in the domain of g,

Let's check if 1/2 is in the domain of f.

f(1/2)=sqrt(6*1/2)=sqrt(3) so this is a number so since 1/2 is in the domain of f then 8 is in the domain of (f o g).

g(4)=1/(4-6)=1/(-2)=-1/2 so 4 is in the domain of g,

f(-1/2)=sqrt(6*-1/2)=sqrt(-3) so this is a problem because you can't square root negative numbers so -1/2 isn't in the domain of f, and therefore 4 isn't in the domain of (f o g).

g(2)=1/(2-6)=1/-4=-1/4 so 2 is in the domain of g.

f(-1/4)=sqrt(6*-1/4)=sqrt(-3/2) so again this is a problem because we can't square root negative numbers so -1/4 isn't in the domain of f, and therefore 2 isn't in the domain of (f o g).

Answer:

The expression which will result in difference of two squares is:

 (–7x + 4)·(–7x – 4)

Step-by-step explanation:

We know that the formula of the type:

(a-b)(a+b)=a²-b²

i.e. it is a difference of two square quantities. (a^2 and b^2)

since,

a= -7x , b=4

(-7x+4)(-7x-4)= (-7x)² - (4)²

=(7x)² - 4²

So the expression is a difference of two square quantities:

(7x)² and (4)²

Hence the answer is (–7x + 4)·(–7x – 4)....

m∠3 + m∠4 = 180°

TRUE - they are supplementary angles

m∠2 + m∠4 + m∠6 = 180°

TRUE - measureas of angles in a triangle add up to 180°

m∠2 + m∠4 = m∠5

TRUE, because

m∠2 + m∠4 + m∠6 = 180° and m∠6 + m∠5 = 180°

therefore m∠2 + m∠4 + m∠6 = m∠6 + m∠5   subtract m∠6 from both sides

m∠2 + m∠4 = m∠5

m∠1 + m∠2 = 90°

FALSE, because m∠1 + m∠2 = 180°

m∠4 + m∠6 = m∠2

FALSE, because

m∠4 + m∠6 + m∠2 = 180°     subtract m∠2 from both sides

m∠4 + m∠6 = 180° - m∠2

m∠2 + m∠6 = m∠5

FALSE, because

m∠5 + m∠6 = 180°          subtract m∠5 from both sides

m∠6 = 180° - m∠5      add m∠2 to both sides

m∠2 + m∠6 = 180° - m∠5 + m∠2

Part 45) The solution of the compound inequality is equal to the interval

(-∞, -0.5] ∪ [1,∞)

Step-by-step explanation:

Part 41) we have

[tex]-4\leq 2+4x < 0[/tex]

Divide the compound inequality into two inequalities

[tex]-4\leq 2+4x [/tex] -----> inequality A

Solve for x

Subtract 2 both sides

The solution of the inequality A is the interval ------> (-∞, -0.5]

Solve the inequality B

[tex]3x+1\geq 4[/tex]

Subtract 1 both sides

Answer:

Bethany is correct because consecutive odd integers will each have a difference of two.

For example: [1, 3, 5, 7, 9, 11, 13, 15, 17, 19, 21...] All those are odd numbers, and have a difference of two.

So every time time we make 'x' an odd number in Bethany's equation, we will get three consecutive numbers.

For example, if 'x' equals '1', then we will get the three consecutive numbers 1, 3 and 5.

If 'x' equals 7, then we will get the three consecutive numbers 7, 9 and 11.

Answer:

A.) Bethany is correct because consecutive odd integers will each have a difference of two

Step-by-step explanation:

The sum of 3 consecutive odd integers is 91. Let the first odd integer is x. The next odd integer will be obtained by adding 2 in x i.e. (x + 2). The third odd integer will be obtained by adding 2 in the second odd integer i.e. (x + 2) + 2 = x + 4

After the information stated we can conclude that:

The 3 odd integers will be:

x  , (x+2) and (x+4)

Their sum is given to be 91. So we can write:

x + (x+2) + (x+4) = 91

Hence, we can conclude that: Bethany is correct because consecutive odd integers will each have a difference of two.

When proving identities, the answer is in the explanation.

Step-by-step explanation:

[tex]\frac{\cos(y)}{1-\sin(y)}[/tex]

I have two terms in this denominator here.

I also know that [tex]1-\sin^2(\theta)=\cos^2(theta)[/tex] by Pythagorean Identity.  

So I don't know how comfortable you are with multiplying this denominator's conjugate on top and bottom here but that is exactly what I would do here.  There will be other problems will you have to do this.

[tex]\frac{\cos(y)}{1-\sin(y)} \cdot \frac{1+\sin(y)}{1+\sin(y)}[/tex]

Big note here: When multiplying conjugates all you have to do is multiply fist and last.  You do not need to do the whole foil.  That is when you are multiplying something like [tex](a-b)(a+b)[/tex], the result is just [tex]a^2-b^2[/tex].

Let's do that here with our problem in the denominator.

[tex]\frac{\cos(y)}{1-\sin(y)} \cdot \frac{1+\sin(y)}{1+\sin(y)}[/tex]

[tex]\frac{\cos(y)(1+\sin(y))}{(1-\sin(y))(1+\sin(y)}[/tex]

[tex]\frac{\cos(y)(1+\sin(y))}{1^2-\sin^2(y)}[/tex]

[tex]\frac{\cos(y)(1+\sin(y))}{1-\sin^2(y)}[/tex]

[tex]\frac{\cos(y)(1+\sin(y))}{cos^2(y)}[/tex]

In that last step, I apply the Pythagorean Identity I mentioned way above.

Now You have a factor of cos(y) on top and bottom, so you can cancel them out.  What we are really saying is that cos(y)/cos(y)=1.

[tex]\frac{1+\sin(y)}{cos(y)}[/tex]

This is the desired result.

We are done.

Answer:

Speed = 8mph

Step-by-step explanation:

Speed of wind = 4mph

Let speed of Darrin with no wind be "x" mph

then resultant speed of Darrin, travelling in direction of wind = (x + 4) mph

Using a result, Time = Distance travelled / Net speed

Time taken by Darrin to travel 6miles in direction of wind = 6 / (x + 4)

When Darrin travel in opposite direction of wind, then its net speed                                                  = (x - 4)mph

Darrin travel 2 miles against the wind in 6/(x + 4) hr

then   Distance =  speed ×  time

           2 =  ( x- 4 ) × ( 6/x + 4)

          2x + 8 = 6x - 24

            4x  =  32

              x = 8 mph

Therefore speed of Darrin skateboard with no wind = 8mph

Answer:

Speed without wind will be 8 mph

Step-by-step explanation:

Now by revising basic formula here

Velocity = Distance/Time. . . . (A)

Assume speed without wind is 'x'

When Darrin is moving against wind to cover 2 miles;

net speed will be x-4

When Darrin is moving along with the wind to cover 6 miles;

net speed will be x+4

Please note that the time for covering distance of 2 miles and 6 miles is same,

So, from equation (A)

Time = Distance/Velocity,

Time for 2 miles will be

Time = 2/(x-4)

Time for 6 miles will be

Time = 6/(x+4)

Since, the time for both distances is same, here we can equate,

2/(x-4) = 6/(x+4)

by cross multiply

2(x+4) = 6(x-4)

2x+8 = 6x-24

4x = 32

x = 8

So, 8 miles per hour is the speed of Darrin if there is no wind.

Answer:

The product of 28w(w-17) is 28w^2 - 476w

Step-by-step explanation:

Given

28w(w-17)

We have to find the product of the monomial and binomial polynomials

The term 28w will be distributed to w-17

So,

= (28w)(w) - (28w)(17)

= 28w^2 - 476w

Therefore, the product of 28w(w-17) is 28w^2 - 476w ..

Final answer:

When multiplying monomials and binomials, you can follow certain rules. Multiply the numerical coefficients, add the exponents of the variables, and then combine like terms if possible.

Explanation:

When multiplying monomials and binomials, you can follow a few rules. For monomials, you simply multiply the numerical coefficients and add the exponents of the variables. For binomials, you can use the distributive property to multiply each term of one binomial by each term of the other binomial. Then, combine like terms if possible.

For example, let's say we have (2x^2)(3x^3). We would multiply the coefficients (2 * 3 = 6) and add the exponents of the variable x (2 + 3 = 5). So the resulting expression is 6x^5.

Both equations start with y =

Set both equations equal to each other and solve for x first:

1/3x-4 = -7/3x +4

Add 7/3x to both sides:

8/3x - 4 = 4

Add 4 to each side:

8/3x = 8

Divide both sides by 8/3

x = 3

Now you have the value of x, replace x in the equation to solve for y:

y = 1/3(3) -4 = 1-4 = -3

y = -7/3(3) +4 = -7+4 = -3

y = -3

X = 3 and y = -3

Answer:

A. right 2, up 3

Step-by-step explanation:

We are asked to find the transformation that occurs from  the graph of [tex]f(x)=x^2[/tex] to [tex]f(x)=(x-2)^2+3[/tex].

Let us recall transformation rules:

[tex]f(x)\rightarrow f(x+a)=\text{Graph shifted to left by a units}[/tex]

[tex]f(x)\rightarrow f(x-a)=\text{Graph shifted to right by a units}[/tex]

[tex]f(x)\rightarrow f(x)-a=\text{Graph shifted downwards by a units}[/tex]

[tex]f(x)\rightarrow f(x)+a=\text{Graph shifted upwards by a units}[/tex]

Upon looking at our given functions, we can see that graph of [tex]f(x)=x^2[/tex] is shifted to right by 2 units as 2 is inside parenthesis. The graph is shifted upwards by 3 units as we have positive 3 outside parenthesis.

Therefore, option A is the correct choice.

Answer:

I don't possess a graph so I'll teach it to you.

Step-by-step explanation:

In a coordinate plane with 4 quadrants, the formula for this equation is SLOPE. This is fairly a very easy topic to learn about. The formula is y = mx + b.

So I assume you forgot to put the "x" after the 3/4.

Anyway, to answer this the "2" in bthe equation is the y-intercept. So the X-coordinate will ALWAYS be ZERO! O basically you plot at (0,2).

Next, you grab the slope. To get it you must use the RISE OVER RUN technique. You rise 3 UP and since it's a POSITIVE SLOPE, 3/4, NOT -3/4, you RUN 4 units to the RIGHT, which gives you (5,4), I believe. And you keep doing that until the graph is finished. And if you want to go backwards from (0,2), you make the RISE AND RUN, NEGATIVE. It's very simple. In the end you should get a line like "/" on your graph which means it's a POSITIVE SLOPE. If it's "\", IT'S A NEGATIVE SLOPE.

Answer:

The answer is A, (3x2-x-6)

Step-by-step explanation:

f(x)=3x2 -4

g(x)=x+2

f(x)-g(x)= 3x2-4 -x-2= 3x2-x-6

Final answer:

The expression (f - g)(x) is found by subtracting g(x) from f(x) and simplifying, which results in 3x² - x - 6, corresponding to option A.

Explanation:

To find (f - g)(x) when f(x) = 3x² - 4 and g(x) = x + 2, we need to subtract the function g(x) from f(x). The operation looks like this:

(f - g)(x) = f(x) - g(x) = (3x² - 4) - (x + 2)

Let's perform the subtraction step by step:

Distribute the negative sign to both terms in g(x):

(3x²- 4) - x - 2

Combine like terms:

3x² - x - 4 - 2

Final simplification:

3x² - x - 6

Therefore, the correct answer is 3x² - x - 6, which matches option A from the provided choices.

Answer:

Slope: [tex]\frac{3}{5}[/tex]

Y-intercept: -3

Equation: [tex]y=\frac{3}{5} x-3[/tex]

Graph is attached.

Step-by-step explanation:

To find your slope using two points, use the slope formula.

[tex]\frac{y2-y1}{x2-x1} \\[/tex]

Your y1 is -6, your y2 is 3.

Your x1 is -5, your x2 is 10.

[tex]\frac{3-(-6)}{10-(-5)} \\\\\frac{9}{15} \\\\\frac{3}{5} \\[/tex]

Now that you have your slope, use it and one of your points in point-slope form to find your y-intercept.

[tex]y-y1=m(x-x1)\\y-3=\frac{3}{5} (x-10)\\y-3=\frac{3}{5} x-6\\y=\frac{3}{5} x-3[/tex]

Answer:

A. In the graph,

Go 5 units left side from the origin in the x-axis then from that point go downward 6 unit, we will get (-5, -6),

Now, go 10 unit right from the origin in the x-axis then from that point go upward 3 unit, we will get (10, 3),

B. The slope of the line passes through (-5, -6) and (10, 3),

[tex]m=\frac{3-(-6)}{10-(-5)}=\frac{3+6}{10+5}=\frac{9}{15}=\frac{3}{5}[/tex]

C. Since, the equation of a line passes through [tex](x_1, y_1)[/tex] with slope m is,

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

Thus, the equation of the line is,

[tex]y+6=\frac{3}{5}(x+5)----(1)[/tex]

For y-intercept,

x = 0,

[tex]y+6 = \frac{3}{5}(0+5)\implies y = 3-6=-3[/tex]

That is, y-intercept is -3.

D. From equation (1),

[tex]5y + 30 = 3x + 15[/tex]

[tex]\implies 3x - 5y = 15[/tex]

Which is the required linear function.

Answer:

D. 9 inches

Step-by-step explanation:

By using proportionality theorem,

Triangle BLM ~ Triangle BAC

[tex] \frac{bm}{bc} = \frac{bl}{ba} [/tex]

as ba = bl + la and as bl = la

Therefore, bl + la = 2bl

[tex] \frac{bm}{bc} = \frac{bl}{2bl} [/tex]

Now, we get,

[tex] \frac{bm}{18} = \frac{1}{2} [/tex]

as bc = 18

Hence,

[tex]bm = 9 \: inches[/tex]

Answer: D. 9 inches

Step-by-step explanation:

Given : The midsegment of Δ ABC is line segment IM.

Such that for side BC ,  BM=MC         [ Show in the picture ]     (1)

and BC= BM+MC    (2)

The length of BC = 18 inches              (3)

From (1) and (2), we have

[tex]BC=MC+MC\\\\\Rightarrow\ BC=2MC[/tex]

Using (3), we have

[tex]2MC=18\text{ inches}\\\\\Rightarrow\ MC=\dfrac{18}{2}=9\text{ inches}[/tex]

Therefore, the length of MC = 9 inches.

Hence, D is the correct option.
