Take the 89 times 5 tests. You get 445 total score you need for an average of 89. Add 82, 89, 92, 87=350 445-350=95 They must get a 95 on next test to get the average of 89
Answer:
119°
Step-by-step explanation:
51+180-112= 119°

Y=mx+b
First use the two point slope formula to find m
(y2-y1)/(x2-x1)
(2-0)/(-9-9)
2/-18
1/-9=m
Next use the point slope formula to find the answer
y-y1=m(x-x1)
y-0=1/-9(x-9)
Now use Distributive Property
y-0=1/-9(x)+1/-9(-9)
y-0=1/-9x+1
Your answer would be
y=-1/9x+1
