How many bracelets did you buy just $50 dollars worth and how much did you buy one bracelet for <span />
Answer:
y = 7/5x + 4
Step-by-step explanation:
use the slope from the equation -5/7 and take the negative reciprocal to get the perpendicular slope = 7/5. Then use the equation y=mx+b. Plug in x and y from the point given and the new slope and solve for b.
(-3) = (7/5)(-5) + b, (-3) = -7 + b, add 7 to both sides. b = 4. Rewrite the equation now to be y = 7/5x + 4

(1 + x) (13) = 13+6.5
13x + 13 = 19.5
13x = 6.5
x = 0.5
