$27 is the price of 9 hamburgers
(0,0) and (4,1)
Find the slope: m = (y2-y1)/(x2-x1) = (1-0)/(4-0) = 1/4
Input m, x1, and y1 into the Point-Slope equation:
y - y1 = m(x - x1)
y - 0 = 1/4 (x - 0)
y = 1/4 x
Answer:
x=-5, x=9
Step-by-step explanation:
we know that
The formula to solve a quadratic equation of the form
is equal to
in this problem we have
equate to zero
so
substitute in the formula
therefore
The solutions are x=-5, x=9
