Answer:
39+4x
Step-by-step explanation:
Since two opposites add up to zero, remove them from the expression
2x3-5x+2+4x2+6x-2x+7x5
Calculate the sum or difference
39+6x-2x

I don’t know lol
Step-by-step explanation:
Answer:
a) y = -500x + 130,000
b)67,500 gallons remaining
c) 260 hours
Step-by-step explanation:
Since water is being removed at a rate of 500 gallons per hour, the slope would be a negative.
a) y = -500x + 130,000
For<u> part b</u> input 125 for x:
y = -500(125) + 130,000
y = 67,500
There are 67,500 gallons remaining
For part c we are solving for the x intercept
0 = -500x + 130,000
Subtract 130,000 from both sides
-130,000 = -500x
x = 260
It will take 260 hours for the pool to completely drain
Answer:
Step-by-step explanation:
A. Right Triangle
If two sides of a right triangle are 3 and 4, that would make the third side = 5.
if the two given sides are both legs, the 3rd side (hypotenuse) would still = 5
if the two given sides are a leg and the hypotenuse then the third side = rad7
