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:
50.65
Step-by-step explanation:
34.60+12.30=46.90
8%=.08
46.90*.08=3.752
add tax to the total-
46.90+ 3.75= 50.65
