Answer:
(The solution is (4, -11).
Step-by-stp explanation:
Let f(x) = g(x) = y:
y = 3x − 23
y = -4.5x + 7 Subtract the second equation from the first to eliminate y:
0 = 7.5x - 30
7.5x = 30
x = 4
Plug this into the first equation:
y = 3(4) - 23
y = -11.
Answer: 1145 feets

Answer:
A/( 1+rt) = P
Step-by-step explanation:
A = P ( 1+rt)
Divide each side by ( 1+rt)
A/( 1+rt) = P ( 1+rt)/(1+rt)
A/( 1+rt) = P
