Answer:
b) 1 / 4
c) -3
Step-by-step explanation:
b) line passing through points (0,-1) (4,0)
slope = (y2 - y1) / (x2 - x1)
= (0 - (-1) ) / (4 - 0)
= 1 / 4
c) line passing through points (-1,2) (0, -1)
slope = (y2 - y1) / (x2 - x1)
= (-1 - 2) / (0 - (-1) )
= -3 / 1
= -3
Answer:

Answers:
After 7 years the car is worth $10,196(,46)
Explanation:
Year 1: $24,950•0,88=21,956
Year 2: $21,956•0,88=19,321(,28)
Year 3: $19,321(,28) •0,88=17,002(,73)
Year 4: $17,002(,73) •0,88=14,962(,40)
Year 5: $14,962(,40) •0,88=13,166(,91)
Year 6: $13,166(,91) •0,88=11,586(,88)
Year 7: $11,586(,88) •0,88=10,196(,46)
100%/x%=95/38
(100/x)*x=(95/38)*x - we multiply both sides of the equation by x
100=2.5*x - we divide both sides of the equation by (2.5) to get x
100/2.5=x
40=x
x=40
now we have:
<span>38 is 40% of 95</span>
