Answer:
y = 3/7x + 51
Step-by-step explanation:
y = 3/7x + 11 is parallel to the line so it means that both of their gradient are same so:
y = mx + c
m= gradient point = (-21 , 42)
= 3/7
now we sub the m and the point into the formula which is y= mx+c because we should find the c first then we can find the equation of the line:
42 = 3/7 (-21) + c
42 = -9 + c
42 + 9 = c
51 = c
c = 51
now you hv to rewrite again the equation become y= 3/7x + 51
So now your final answer is : y = 3/7x +51

Answer:
C. The equation has two valid solutions and no extraneous solutions.
Step-by-step explanation:
See attached file for complete work.
The net rate per day is 520 miles per day because 1560 miles divided by 3 days is 520/day. Therefore, we need to see how many days (520 mi) fit into 3640 mi.
3640/520=7
Therefore, it will take 7 days to travel 3640 miles.
