Step-by-step explanation:
1.) Plug in one of the points.
y = 8x + b
6 = 8(4) + b
2.) Solve for b (or [?])
32 cancels out on the right side.
Subtract 32 from 6, which is -26
3.) -26 = b
4.) Check with other point:
-2 = 8(3) + b
-2 = 24 + b
Cancel out 24 on the right side: 24-24 = 0
-2 - 24 = -26
-26 = b
Answer:
the answer is 71.2
Step-by-step explanation:
4×4=16
6.9×2=13.8
13.8×4=55.2
55.2+16=71.2
You subtract the % that the sale is and take it away from 100%. You get 75% then take the original price and divide it by .75
Find a common denominator and then add.
3/5=6/10
6/10+1/10=7/10
