Answer:
x = 6
Step-by-step explanation:
Ratio between the top and bottom of the adult's chair is 7/14, or 1/2
So that means, x is equal to 12 x 1/2, or 6.

Answer:
10
Step-by-step explanation:
Make the words into an equation:
((n^3/16)-2)+8
Substitute in 4 for n:
((4^3/16)-2)+8
Simplify and solve:
4^3=64
64/16=4
4-2=2
2+8=10
Answer:
The equation for the function g is g(x) =
x -
⇒ C
Step-by-step explanation:
The form of the equation of the linear function is g(x) = m x + b, where
The formula of the slope is m =
, where (x1, y1) and (x2, y2) are 2 points on the line represents the function
From the given table
∵ The points (-3, -13) and (2, -1) belong to the function g(x)
∴ x1 = -3 and y1 = -13
∴ x2 = 2 and y2 = -1
→ Substitute them in the formula above to find m
∵ m =
=
= ![\frac{12}{5}](https://tex.z-dn.net/?f=%5Cfrac%7B12%7D%7B5%7D)
∴ m = ![\frac{12}{5}](https://tex.z-dn.net/?f=%5Cfrac%7B12%7D%7B5%7D)
→ Substitute in the form of the equation above
∴ g(x) =
x + b
∵ There is only one choice that has m = ![\frac{12}{5}](https://tex.z-dn.net/?f=%5Cfrac%7B12%7D%7B5%7D)
∴ The equation for the function g is g(x) =
x - ![\frac{29}{5}](https://tex.z-dn.net/?f=%5Cfrac%7B29%7D%7B5%7D)
∴ Choice C represents the equation of function g
