Step-by-step explanation:
2x-8=x+4
Get the x to the other side and the 8 to the opposite
2x-x=4+8
X=12
It’s B the answer is -3 and 4+(-7) is equivalent
Answer:
8 hours
Step-by-step explanation:
basic equation
Q (flow rate) = V (volume)/ t (time)
so to find the time we just rearrange the equation and become
t = V/Q
V of cylinder
V = πr²T
and r (radius) = ½ diameter
V = 3.14 x 5² x 1.4
V = 109.9 m³
if the Q is 13 m³/hour then
t = 109.9/13 = 8.453 hours
round to nearest hour = 8 hours

Nonlinear- y= 2x^2+ 4
