Answer:
$3.00 is the constant
Step-by-step explanation:
let x be the mile driven then
total charge=$3.00+[x($0.30)]
2 x 2 x 2 + 3 x 3 x 3 = 35
Answer:
Step-by-step explanation:
f(x) = –2x² + 12x + 5
= -2 (x² - 6x - 5/2)
= - 2 ( x² -2(3)x +9 - 9 - 5/2)
= - 2 ( (x - 3)²-23/2)
f(x) = - 2 ( x - 3)²+23 .....vertex form
the vertex is : (3 : 23) Maximum at (3, 23) because a = -2 and a< 0

Answer:
(f+g)(x) = 5x +1
Step-by-step explanation:
Substitute the given expressions and simplify.
(f+g)(x) = f(x) +g(x)
(f+g)(x) = (2x +7) +(3x -6) = (2x +3x) +(7 -6)
(f+g)(x) = 5x +1
