Answer:
19.5 gallons
Step-by-step explanation:
2028/x=100/30
<span>(2028/x)*x=(100/30)*x </span>we multiply both sides of the equation by x
<span>2028=3.3333333333333*x </span>we divide both sides of the equation by (3.3333333333333) to get x
<span>2028/3.3333333333333=x </span>
<span>608.4=x </span>
<span>x=608.4
so there for its 608.4 hope this helps.</span>
Answer:
A) (-5, -34)
Step-by-step explanation:
f(x) = x^2 + 10x - 9
We complete the square to get the equation in vertex form
Take the coefficient of the x term and divide by 2 then square it. We add it and then subtract it not to change the value of the equation
f(x) = x^2 + 10x +(10/2)^2 - (10/2)^2 - 9
f(x) = x^2 +10x +25 -25 -9
f(x) = (x^2 +10x +25) -34
The term in parentheses simplified to (x+10/2) ^2
= (x+5)^2 -34
= (x - -5)^2 -34
This is in the form (x-h)^2 +k
The vertex is (h,k) h=-5 and k=-34
(-5,-34)
