Answer:
Step-by-step explanation:
Plug in the numbers & solve for 5x, eventually eliminating the 5 to solve for x, which the variable should be on the left side, always.
F(x) = 4x+3
f(-1/2) = 4(-1/2)+3
f(-1/2) = -2+3
f(-1/2) = 1
-----------------------
g(x) = 3x
g(-1/2) = 3(-1/2)
g(-1/2) = -3/2
-----------------------
Replace x with -1/2 to go from
f(x)*g(x)
to
f(-1/2)*g(-1/2)
So you'll multiply the results of 1 and -3/2 to get 1*(-3/2) = -3/2
-----------------------
The final answer is -3/2
Amount = 100000(1 + 0.04)^20 = 100000(1.04)^20 = $219,112.31
Compound Interest = $219,112.31 - $100,000 = $119,112.31
complete square = 100 square yards
triangle = 1/2 x base x height = 1/2 x 10 x 5 = 25 square yards
100-25 = 75 square yards
shaded area = 75 square yards
