Answer:
x = (3 + 8y) / (y - 1)
Step-by-step explanation:
y = (x + 3) / (x - 8)
Make x the subject
y = (x + 3) / (x - 8)
Cross product
y * (x - 8) = (x + 3)
xy - 8y = x + 3
xy - x = 3 + 8y
Factorize the left hand side of the equation
x( y - 1) = 3 + 8y
Divide both sides by (y - 1)
x = (3 + 8y) / (y - 1)
Jake’s family traveled a total of 1,543 miles
Notice that the sequence involves subtracting 10 units from the previous term. Then, we are in the case of an arithmetic sequence with common difference = -10, since we build the next rem by subtracting 10 from the previous. so we have:
term 1 = 42
term 2 = 42 - 10 = 32
term 3 = 32 - 10 = 22
term 4 = 22 - 10 = 12
term 5 = 12 - 10 = 2
term 6 = 2 - 10 = -8
term 7 = -8 - 10 = -18
