We are asked to determine the value of a such that the function f(x) = ax^2 + 5 is fit for the point given (-1,2). In this case, we substitute 2 to y and -1 to x. The result is then 2 = a*(-1)^2 + 5 ; 2 = a + 5; a is then equal to -3
Assuming that the mix disolves into the 20 gallons and doesn't take up space
1:2
x:20
1/2=x/20
multiply btoh sides by 20
10=x
answer is 10 cups of mixture
As you move from each place to the left one place, the value increases by 10. If you move right a place, the value decreases by 10.
$3.60 for 2 cups would be $1.80 for one cup.
$3.60 for 2
$5.40 for 3
$7.20 for 4
$9 for 5
$10.80 for 6
$12.60 for 7
$14.40 for 8
Answer:
6 units is the answer im pretty sure
