y ----> the cost of buying T-shirts from Paula’s Printing in dollars
take two points from the given data
we have
(2,43) and (4,86)
step 1
Find the slope
The formula to calculate the slope between two points is equal to
substitute the values in the formula
step 2
Find the equation of the line in point slope form

we have

substitute

step 3
Convert to slope intercept form

Isolate the variable y



This linear equation represent a proportional relationship (the line passes through the origin)

Answer:
530
Step-by-step explanation:
200+6(55)
6x55=330
200+330=530
(5x^2 + x - 4)(x + 2) = x(5x^2 + x - 4) + 2(5x^2 + x - 4) = 5x^3 + x^2 - 4x + 10x^2 + 2x - 8 = 5x^3 + 11x^2 - 2x - 8
Answer:
X = 8
