100/x=300/45 Factor out 100/x=15×20/15×3 Cancel common factor
100/x=20/3 100(3)=20(x) 300=20x 300/20=X 15=x
Answer:
f(x) = -½ x - 5x (the 3rd option)
Step-by-step explanation:
f(4)= -½(4) - 5(4)
= -2 - 20
= -22
The area of a triangle is found using the formula Area = 1/2 x base x height.
Base = 8
Height = 18.
The area of 1 triangle = 1/2 x 8 x 18 = 72 square units.
There are a total of 4 sides, so total area = 72 x 4 = 288 units ^2

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
Choice C
