Jenny works in a picture framing shop. She has a function f(x) equals X +2 that find the size of a square frame, given a picture

of side length X in inches. She has a function p(x) equals 3X that gives the price in dollars for the frame. What is the single function that Jenny can use to give a customer a price for a picture with an edge length of X

Given:

The function for size of a square frame is

f(x)=x+2

where, x is the side length of the picture.

The function for the price in dollars for the frame is

p(x)=3x

To find:

The single function for the price of a picture with an edge length of x.

Solution:

We know that, for a picture with an edge length of x.

Size of a square frame = f(x)

Price in dollars for the frame = p(x)

Single function for the price of a picture with an edge length of x is

(p\circ f)(x)=p(f(x))

(p\circ f)(x)=p(x+2)       [\because f(x)=x+2]

(p\circ f)(x)=3(x+2)           [\because p(x)=3x]

Let the name of this function is c(x). So,

c(x)=3(x+2)

Therefore, the required function is c(x)=3(x+2).

Solve for x. Show all work. 2/3 (x+7) =10
Anna35 [415]

Answer:

answer is 8

Step-by-step explanation:

2/3(x+7)=10

2x/3+14/3=10

2x/3=10-14/3==>30-14/3

2x/3=16/3

x=16/3*3/2

x=8

What is the area of the figure abcd
expeople1 [14]

Answer:

66 square inches

Step-by-step explanation:

The area of the figure can be found by adding the area of the rectangle and the triangle together.

The area of a rectangle is found A = l*w. Here l = 10 and w = 6. So the area of the rectangle is 10*6 = 60.

The area of a triangle is found A = 1/2 b*h. Here b = 2 from 12-10 = 2 and h = 6. So the area of the triangle is 1/2 * 2* 6 = 6.

The area together is 60 + 6 = 66 square inches.

The function T(n) is defined below. Which of the following are equal to T(8)? Check all that apply.
Firdavs [7]
You are told to choose the choices equal to T(8). T(8) means that you need to find the possible ways to write the y-value when n = 8, since 8 is being substituted in for "n."

1) First, plug in n = 8 into the equation you're given, <span>T(n) = 4n - 5:
T(8) = 4(8) - 5
T(8) = 32 - 5
T(8) = 27

That is answer choice C, making choice C correct. You can eliminate choice B, since 27 </span>≠ 37.

2) Check answer choice A. Is T(5) + T(3) = 27? 
T(5) means you need to plug in 5 for n. T(3) means you need to plug in 3 for n.
T(5) + T(3)
=  [4(5) - 5] +  [4(3) - 5]
= [20-5] + [12-5]
= 15 + 7
= 22 

Since 22 ≠ 27, you can eliminate choice A.

3) Check answer choice D. Is T(7) + 4 = 27? T(7) means you need to plug in 7 for n.
T(7) + 4 
= [<span>4(7) - 5] + 4 
</span>= [28 - 5] + 4
= 23 + 4
= 27

Since 27 = 27, answer choice D is also correct!

--------

Answer: Choice C (27) and Choice D (T(7) + 4)
