Mary = M Chris = C
M = 3C-4
M-3=C+9 --> M=C+12
3C-4=C+12
2C=16
C=8
M=3C-4 --> C=8
M=3(8)-4
M=24-4
M=20
Mary is 20, and Chris is 8

Answer:
f, h, g
Step-by-step explanation:
You can look at the slope of the tangent lines to the graphs at any given x-value. At x=5, we see that g(x) is the flattest curve and f(x) is the steepest.
In order from greatest to least growth rate, the functions are ...
f(x), h(x), g(x)
Answer:
Step-by-step explanation:
If two polygons are similar, then corresponding sides are in proportion.
The corresponding sides:
4 → x
y → 15
3 → w
2 → 6
z → 9
therefore:
<em>cross multiply</em>
<em>divide both sides by 6</em>
