We have f(x) = 0;
Then x^2 - 1 - 2x - 2 = 0;
(x - 1)(x + 1) - 2(x + 1) = 0;
(x + 1)(x - 1 - 2) = 0;
(x + 1)(x - 3) = 0;
x + 1 = 0 or x - 3 = 0;
x = -1 or x = 3;
The zeroes of f are -1 and 3.
$28 x 7 days = $196/week
$196 - $108 = $88
$88 ÷ 0.14 = 628.5 mi
He would need to drive 628.5mi before the Avis price is the same as the Hertz price.
Answer:
One real solution (which is x = 2)
Step-by-step explanation:
8-4x = 0
8 = 4x
8/4 = 2
x=2
Can be solved with no different solution
Answer:
8/13
Step-by-step explanation:
(−4,−4);(9,4)
(x1,y1)=(−4,−4)
(x2,y2)=(9,4)
Use the slope formula:
m=
y2−y1
x2−x1
=
4−−4
9−−4
