Answer:
26 miles per gallon
Step-by-step explanation:
This is how you do it.
y = a(x - 3)(x - 8)
<span>-2 = a(-1 - 3)(-1 - 8) </span>
<span>-2 = 36a </span>
<span>- 1 / 18 = a </span>
<span>y = ( - 1 / 18)(x^2 - 11x + 24) </span>
<span>y = (- 1 / 18)x^2 + (11 / 18)x - (3 / 2)
</span>

Zero is equal to its negative
Answer:
Step-by-step explanation:
We assume your equations are intended to be ...

Then the profit equation is ...

The partial derivatives of profit with respect to x and y are zero when profit is maximized.
∂P/∂x = 0 = -2x +2y +2
∂P/∂y = 0 = 2x -18y +94
Simplifying, these equations are ...
Substituting the first into the second gives ...
x -9(x -1) = -47
-8x = -56
x = 7
y = 7 -1 = 6
The company will maximize profit by selling 7000 panels of type A and 6000 panels of type B.
Answer:
<em>8 14/45</em>
Step-by-step explanation:
First, place 8/9 anywhere there is a y:
6+8(8/9-3/5)
Next, do what is in the parenthesis. Make both fractions have the same denominator.
6+8(40/45-27/45)
And now subtract:
6+8(13/45)
Now, multiply 8 and 13/45:
6+ 104/45
Convert the fraction to a mixed fraction:
2 14/45
Finally, add 6:
8 14/45
