The y intercept of the function shown is at -4........and it has a positive slope......
Answers C and D have negative slopes, so we can eliminate them
Answer A has a positive slope, but it has a positive y intercept
Thus, "B" is correct......
36xy-72ac factors as
36 [ xy - 2ac ]
Here's all you need to remember : two non-zero numbers with the same sign, multiplied or divided are positive............different signs, negative
$50 - $83 + $45 - $31 =
[$50 + $45] - [ $83 + $31] =

Notice........13776 - 7998 = 5778
And 19554 - 13776 = 5778
So.....we would speculate that the next sum = 19554 + 5778 = 25332

So....... 7998 + 13776 + 19554 + 25332 = 66660

[-9y^2-3y] / [ -6y^2-6y ] factor top/bottom
-3y [ 3y + 1] / ( -6y [ y + 1] ) =
[3y + 1 ] / [2 (y + 1) ]
400(0.8)^7 ≈ 83.88608
Circumference = 2 * pi * (d/2) = 2 * pi * (20/2) ≈ 62.83 cm
Area = pi * (d/2)^2 = pi * (20/2)^2 ≈ 314.16 cm ^2
