The constant of proportionality (k) equals the total price (y) divided by the number of cans (x).
Step-by-step explanation:
1) $65 ÷ $6.50 = $10
2) Check Work: $10 × $6.50 = $65
$10 is your missing factor :)
Hope This Helps :)
8-x(y)
or in words 8 minus x times y do the 8 minus x first then the times y
<span>Let each side perpendicular to the river be
"x".
Then the side parallel to the river is "2400-2x".</span>
The function would be:
<span>A(x) = x(2400-2x)
</span>
And it would be: A(x) = 2400x - 2x^2
To solve the equation:
<span>
You have a quadratic with a = -2 and b = 2400
</span>
Maximum Area happens where:
x = -b/2a
= -2400/(2*-2)
<span>= 600 ft. (width)
</span>
To find the length it will be:
<span>= 2400-2x = 2400-2*600 = 1200 (length)</span>
