Answer:
Choice C
Step-by-step explanation:
f: initial value of 200 decreasing at a rate of 4%
g: initial value of 40 increasing at a rate of 8%
f is decreasing so it must go down starting at 200
That eliminates a and d
g is increasing and starts at 40 That eliminates a
We must look at b and c
g is increasing faster than f is decreasing

Answer:
x=10 or x=-2
Step-by-step explanation:
add 28 to both sides
(x-4)^2=36
sqrt both sides
remember to get positive and negative roots
x-4=+/-6
add 4 to both sides
x=4+/-6
x=4+6 or x=4-6
