Answer:
B. y = 4x - 5
Step-by-step explanation:
Line y = - 1/4 x - 1, has slope = - 1/4.
For perpendicular line slope should be negative reciprocal and = 4.
Slope point form is y - y1 = m(x - x1).
y - 7 = 4 (x - 3)
y - 7 = 4x - 12
y = 4x - 5
a 80
7200 / 90 = 80
<em> 4 pairs of earrings </em>
3.75 e + 9.50 < 25
3.75 e < 25 - 9.50 = 15.50
e < 15.50 ÷ 3.75 ≈ 4.13
e =<em> 4 pairs of earrings</em>
