Answer:

x = y^2 + 4y + 3

Step-by-step explanation:

f(x) = ( x + 2 )^2 - 1

y = ( x + 2 ) ^ 2 - 1

y = ( x^2 + 4x + 4 ) - 1

y = x^2 + 4x + 4 - 1

y = x^2 + 4x + 3

x = y^2 + 4y + 3

(switch from y to x and x to y)

I hope that helps!

pj = 14

jb = 28

Plug in the corresponding numbers to the corresponding variables:

pb = pj + jb

pb = 14 + 28

pb = 42

Water flows back and forth between a small and large tank. When water is moving into a tank the flow rate is positive, and when
Lady_Fox [76]

Answer: C. 100

Step-by-step explanation:

If  the large tank is flowing at a constant rate of  -6 per minute then we have to know that the water is moving from the tank. So is asking how many water will be left in the tank after 25 minutes.

You could use the equation

y = -6x  + 250  where y is the amount of water left in the tank and x is the number of minutes.

So if x is 25 then plot it in and solve for y.

y = -6(25) +250

y = -150 +250

y= 100
