Which equation is the inverse of y=9x^2-4

The answer is 9x^2-4=y because when you inverse an equation you reverse it.

First swap the x and y variable, then isolate y.

y = 9x^2 - 4
x = 9y^2 - 4
x + 4 = 9y^2
(x+4)/9 = y^2

plus or minus
\sqrt{((x + 4) \div 9}  = y

Andrei [34K]
X^2-2=x
x^2-2+x=0

Suppose Randolph decides that the radius of his pool will be 50 meters. What volume of water, in cubic meters, will be needed to
tangare [24]
If we assume the pool to be a semi sphere,  then the volume would be
<span>
V pool = 1/2 * [4/3*pi*r**(3)]

</span>where r is the radius = 50m

V pool = 1/2 * [4/3*3.14*50**(3)]
<span>
V pool =
261799.3878 m</span>³

If we round up >>> V water in the pool = 261800 m

irina1246 [14]

Answer:

<em>The relative change from Bloomington to Kokomo is  -12.449...%</em>

Step-by-step explanation:

The fair market rental rate for Bloomington is $747 and for Kokomo is $654.

So, the amount of relative change from Bloomington to Kokomo will be:  (\$654-\$747)=-93 dollar.

<em>Formula for percentage of relative change = (Amount of relative change/ Initial amount)× 100%</em>

So, the percentage will be:  \frac{-93}{747}\times 100\% =-12.449.... \%

Equation, find y when x=-3.<br><br> y = -x + 5<br><br> When x = -3, y =
Step2247 [10]
I think y = 8. Since x = -3 then the equation would be y = -1(-3) +5. -1 times -3 equals 3. So now the equation is y = 3 +5. That would give you 8.
