its A
Step-by-step explanation:
$47.99+$2.88=$50.87 (total cost)
$60.00-$50.87=$9.13
he should get back $9.13
Answer:
y = -2x/3 + 2
Step-by-step explanation:
A(0,1), B(2,4)
slope of AB = (yb-ya)/(xb-xa) = (4-1)/(2-0) = 3/2
Slope of perpendicular to AB
m = -1/(3/2) = -2/3
Point to lie on perpendicular, P(0,2)
Equation of perpendicular, point-slope form
(y-yp) = m(x-xp)
y-2 = -(2/3)(x-0)
y = -2x/3 + 2
9 hours because 8 x 3 = 24 and 3 x 3 = 9
