Given the parent function f(x)=x^2 describe the graph of y=(0.2x)^2
Yanka [14]
We have the following function:
 f (x) = x ^ 2
 We have the following transformation:
 Expansions and horizontal compressions
 The graph of y = f (bx):
 If 0 <b <1, the graph of y = f (x) expands horizontally by the factor of 1 / b. 
 Applying the transformation:
 y = (0.2x) ^ 2
 The factor is:
 1 / b = 1 / 0.2 = 5
 Answer:
 
b. expanded horizontally by a factor of 5

Can anyone help and explain how to do this it’s very confusing?
Margarita [4]

Answer:

Find the slopes; 123 servings

Step-by-step explanation:

When you look at the graph and table, find out which ones have a slope of 1/2

To find slope you have to use this equation

\frac{y - y^1}{x - x^1}

So for each graph and table, calculate the slope using that formula :)

For the second question,

For every 10 students, the amount of juice dispensed was

7*4 + 3*8 = 52

So divide 52 by 10 to get 5.2

Then divide the total amount of juice (640) by 5.2 and that rounds to about 123 servings of juice

What is the value of x in the equation 2(5x + 4) = 17?
andrew11 [14]

Answer:

\frac{9}{10}

Step-by-step explanation:

2(5x+4)=17,\\10x+8=17,\\10x=9,\\x=\frac{9}{10}

Analysis:

2(5x+4)=17

  • Distribute

10x+8=17,

  • Subtract 8 from both sides to isolate x

10x=9

  • Divide both sides by 10 to isolate x

x=9/10 (ans)
