Answer:
3. 4,715 (estimate: 5,000)
4. 3,672 (estimate: 3,300)
5. 18,040 (estimate: 16,000)
6. 9,060 (estimate: 9,000)
Explanation:
It is reasonable if your answer is somewhat close to the estimate.
The two equations are:
y=.17x+35.96
y=.12x+49.96
He would have to drive 280 miles for both of them to cost the same.
Answer:
The point slope formula is
(y−y1)=m(x−x1)
Where m = the slope calculated as y2−y1x2−x1
(x1,y1)(x2,y2)
(-4 , 1) (-2 , 3)
Solve for the slope
m = 3−1−2−(−3) = 21 = m = 2
(y−3)=2(x−(−2)) Plug in known values.
y−3=2(x+2) Simplify signs
y−3=2x+4 Use Distributive property
y=−2x+4+3 isolate the y variable
answer (y = −5x+7 ) Simplify
1400, as 1200 + 200 = 1,400 and 1600 - 200 = 1400.
