f(x) = x+4
g(x) = 3x2 - 7



Find (f•g)(x)

Answer:

(-5, -1)

Step-by-step explanation:

When two lines intersect, their x and y values are equal. So,

x = 3y - 2 must equal -7 - 2y = x

x = 3y - 2 = -7 - 2y = x

Let's look at the two middle equations and solve for y.

3y - 2 = -7 - 2y

Add 2y to both sides

5y - 2 = -7

Add 2 to both sides.

5y = -5

y = -1

Now, let's find x. You can use either equation for this step.

When y = -1, then 3y - 2 =

(3)(-1) - 2 = -3 - 2 = -5

So, x = -5, and y = -1

Thus, the answer is (-5, -1)

I hope this helps! Feel free to ask any questions!

Answer:

4,0

Step-by-step explanation:

Find where the two lines intercept at.

They both intercept at 4,0

Answer and Step-by-step explanation:

The solution is (4, 0)

This is because the graphs intersect at this point, which would be their solution.

Answer:

180°

Step-by-step explanation:

ABCD is a parallelogram.

Measures of the opposite angles of a parallelogram are equal. Here [tex] \angle A, \:\: \angle C \: \: and\:\: \angle B, \:\: \angle D[/tex] are opposite angles.

[tex] \therefore m\angle A = m\angle C = 110\degree [/tex]

[tex] \& \:m\angle B = m\angle D = 70\degree [/tex]

[tex] m\angle A + m\angle B =110\degree + 70\degree [/tex]

[tex] m\angle A + m\angle B =180\degree [/tex]

Answer:

Step-by-step explanation:

a)  looks like about 180  ( by the graph)

b)  February was the only month where the average was about 70

c) yes, b/c this graph has months along the bottom,  as the independent variable and the rain fall in each as the dependent so the amount of rain is a function of each month

Answer:

Yes , i agree with Noah that the equation would be 3(x + 7) = 57

Step-by-step explanation:

P.S - The exact question is -

To find  - Noah writes the equation 3 (x+7)=57 to represent the situation.

               DO YOU agree with him? Explain your answer.

Proof -

Yes , i agree with Noah

Because in the figure we can see that there is x written 3 times and 7 written 3 time and whole the values is equal to 57 .

Because 57 is divided into x 7 x 7 x 7

∴ we can write it as

3 times x + 3 times 7 = 57

⇒3(x) + 3(7) = 57

⇒3(x+7) = 57

Ans Noah give the same equation 3 (x+7)=57

So, I agree with Noah.

Given:

The given figure represents the original parallelogram and the reduction.

To find:

The length of side A in the new parallelogram.

Solution:

We know that the original figure is always similar to its reduction. So, both parallelograms are similar to each other.

The corresponding sides of similar figures are proportional.

[tex]\dfrac{45}{18}=\dfrac{5}{A}[/tex]

[tex]45\times A=5\times 18[/tex]

[tex]45A=90[/tex]

Divide both sides by 45.

[tex]A=\dfrac{90}{45}[/tex]

[tex]A=2[/tex]

The length of side A in the new parallelogram is 2 cm. Therefore, the correct option is A.

Step-by-step explanation:

60% = 0.6

15% = 0.15

10 = 0.15

Answer:

24

Step-by-step explanation:

Let x represent total number of vehicles

Let T represent number of trucks

Let V represent number of vans

Let B represent number of buses

Convert percent's to decimals:

60% = 0.6

15% = 0.15

Set up equations:

T = 0.6x

V= 0.15x

B= (1 - 0.6 - 0.15)x

For buses, the remaining portion of the 100% of vehicles is 100% -60% -15%

Since we know there are 10 buses, set B=10

B= (1 - 0.6 - 0.15)x

10= (1 - 0.6 - 0.15)x

10= 0.25 x

Divide both sides by 0.25 so that we get:

10/0.25 = x

x= 40

We now know there are 40 vehicles present.  To find the number of trucks, we take 60% of the total number of vehicles

T = 0.6x

T= 0.6 (40)

T= 24

Therefore there are 24 trucks.

4(9a - 4)

Step-by-step explanation:

Answer:

4(9a - 4)

Step-by-step explanation:

Given

36a - 16 ← factor out 4 from each term

= 4(9a - 4)

Answer:

19 h

Step-by-step explanation:

The angles of A and B are 45 degrees. This is true because the other angle is a right angle (90 degrees) and if you are making a triangle the degrees of the sides have to = 180 to be a complete triangle. The triangle is complete, so I took 180 – 90 = 90 ÷ 2 = 45.

The angle of C is 115 because it is a supplementary angle. A supplementary angle is an angle that has two angles with a sum of 180 degrees and 180 – 65 = 115

1) 3 , 2)Add 8 floats 3) -2 4) Remove 8 anchors.

Step-by-step explanation:

Answer:

Step-by-step explanation:

Given quadratic equation is,

y = -2x² + 4x + 5

y = -2(x² - 2x) + 5

y = -2(x² - 2x + 1 - 1) + 5

y = -2(x² - 2x + 1) + 2 + 5

y = -2(x - 1)² + 7

This equation is in the vertex form of the quadratic equation,

y = a(x - h)² + k

where, (h, k) is the vertex of the parabola.

Therefore, vertex of the given quadratic equation is (1, 7)

The equation can be rewritten as y = -2(x - 1)² + 7.

Therefore, the vertex of the graph of the function y = -2x² + 4x + 5 in the xy-coordinate plane is located at the point (1, 7).

Step-by-step explanation:

A group of 10 people is choose a chairperson and vice-chairperson. They put all 10 peoples names into a bar. The first name drawn becomes chair. The second name drawn becomes vice-chair. How many possible combinations of chair and Vice-chair are there ?

This is calculated using the Permutation formula

nPr = n!/(n - r)!

Where:

n = 10 people

r = 2 = 2 positions to be filled , Chairman and Vice chairman

Hence:

10P2 = 10!/(10 - 2)!

= 90 ways

Answer:

n = 14

Step-by-step explanation:
