Answer:
13x + 7 + 4x + 15 = 90
17x + 22 = 90
17x = 68
x = 4
4(4) + 15= 16 + 15= 31
13(4) + 7 = 52 + 7 = 59

Answer: Choice A -- f(x) = (1/3)*|x|
============================================
The input of a function is x and the output is y = f(x)
To vertically compress a function, we will multiply the y value by some fraction smaller than 1. This is so that the y coordinates are a fraction of what they once were.
In this case, we multiply y by 1/3 so that something that has a y coordinate of y = 81 becomes y = 27 (divide by 3)
So we have y = f(x) become (1/3)*y = (1/3)*f(x) = (1/3)*|x|

Answer:
D. 116
Step-by-step explanation:
Let the grasshoppers with a white marking be 2x.
Let the grasshoppers without a white marking be 3x.
2x + 3x = 290
5x = 290
x = 290 / 5
x = 58
 
The grasshoppers with a white marking
= 2x
= 2 ( 58 )
= 116
