Option A is not a function because it has two -5's
Option B is not a function because it has two -2's.
Option C is a function.
Option D is not a function because it has two 6's.
Answer:
18.72 cubic feet
Step-by-step explanation:
Volume of the aquarium = lwh
- l = 5.2 ft,
- w = 1.8 ft
- h = 2 ft
V = 5.2*1.8*2 = 18.72 cubic feet
Answer:
y = -2
Step-by-step explanation:
The horizontal line through this point has a slop of 0
Answer:
the answer is 7
Step-by-step explanation:
Add the same term to both sides of the equation
-x=7x-56
−x=7x−56
−x−7x=7x−56−7x
Answer:
The solutions are -0.65 and 4.65.
Step-by-step explanation:
3x^2 - 12x = 9
Divide both sides by 3
x^2 - 4x = 3
To make a square with "x^2 - 4x", you need to have a "+ 4" after it so it can be simplified as (x-2)^2. So add 4 to both sides.
x^2 - 4x + 4 = 7
(x-2)^2 = 7
x - 2 = (square root) of 7
x = 2 (+/-) (square root) of 7.
x = {-0.65, 4.65}
The solutions are -0.65 and 4.65.
hope this helps:)sorry if it doesnt
