Answer:
A
Step-by-step explanation:
Since she's not spending more than $32, the equation is 2h + 8 ≤ 32.
Isolate h to find the maximum number of hours she can rent the boat:
2h + 8 ≤ 32
First, subtract 8 from both sides.
2h ≤ 16
Then divide both sides by 2.
h ≤ 8
h, the number of hours, must be less than or equal to 8, so 8 is the maximum number of hours Bernice can rent the boat for.
Answer: -7 (30h - 11) / 4h
Step-by-step explanation:
Answer:
1
x = 0, x = 3
2
x = -3, x = 3
3
x = -2/3, x = 1
4
x = -1, x = 1, x = -3/2
Step-by-step explanation:
1
3x^2 - 9x = 0
3x(x - 3) = 0
when 3x = 0, x = 0
when x - 3 = 0, x = 3
2
x^2 - 9 = 0
(x - 3)(x + 3)
when x + 3 = 0, x = -3
when x - 3 = 0, x = 3
3
3x^2 - x = 2
3x^2 - x - 2 = 0
(3x + 2)(x - 1 ) = 0
when 3x + 2 = 0, 3x = -2, x = -2/3
when x - 1 = 0, x = 1
4
2x(x^2 - 1) + 3(x^2 - 1) = 0
2x^3 - 2x + 3x^2 - 3 = 0
2x^3 + 3x^2 - 2x - 3 = 0
(x + 1)(x - 1)(2x + 3) = 0
when x + 1 = 0, x = -1
when x - 1 = 0, x = 1
when 2x + 2 = 0, 2x = -3, x = -3/2
It would be 2 root 2
bc it simplifies to root 2 and root 4
root 4 simplifies to 2
so its 2√2
