Answer:
c) 98
Step-by-step explanation:
a. 26 - 676
b. 42 - 1764
c. 98 - 9604
d. 1 - 1
e. 11 - 121
1) y=mx+b
m=slope
m=-3/7 in y=-3/7x+20
2) Since the slope is negative it is decreasing, as seen on a graph. So, the tire tread would be decreasing by the month (x).
3) y=mx+b
b=y-intercept
b=20 in y=-3/7x+20
The equation will be A sub n=6 ×(2)^n-1
or y=6×(2)^x-1
Answer:
3400
Step-by-step explanation:
25000
- 7000 x .10= 700 calculate 10% tax
——————
=18000 x .15 =2700 calculate tax over 7000 at 15%
total tax. = 3400
40:260 is the ratio for this problem
