so if you buy 2 jumpers it will be the cost of 1
and 30% of 50 is 15 so 15 + 15 = 30 plus 45 =

Answer:
7. y = x + 4
8. y = -3x - 2
Step-by-step explanation:
7. m = 1 , b = 4
y = mx + b will be y = x + 4
8. (1,-5) and (-3,7)
Slope (m) = 7 - (-5) / -3 - 1
= 7 + 5 / -4
= 12 / -4
= -3
y = mx + b will be y = -3x -2
It is B. X=10 y=184/4=46.
