Answer:
-4/3
Step-by-step explanation:
Use the slope formula:

-4 - 12/ 13 - 1
-16/12
Simplifies to -4/3
When he cubed ,
Result is x³
On further squaring x³, he got = (x³)²

<h3>Therefore, k =
6</h3>
Answer:
Equations 1 & 3 are correct.
Explanation:
Equation 2's actual answer is -8, and Equation 4's actual answer is positive 7.
Time out = d/so = d/523
time back = d/sb = d/415
t = time out + time back
11 = d/523 + d/415 find common deneminator
11 = (415d + 523d)/(523*415)
11*523*415 = 415d + 523d
2387495 = 938d
d = 2545 miles
hope this help
