Answer:
irrational
Step-by-step explanation:
It cannot be expressed as a fraction
Assuming that X represents the number of hours worked and f(x) the number of cars washed, the equation would be f(x)=11x+14x.
The 11x represents the number of cars washed by Arianna in x number of hours and the 14x represents the number of cars washed by Matthew in x number of hours. You add the two because they are each washing their own car at their own pace but working on one lot.
Answer:
d) x+y = 4
Step-by-step explanation:
(−1, 5) and (1, 3)
y = mx + b
m = (3 - 5) / (1 - (-1)) = -2 / 2 = -1
b = y - mx = 3 - ((-1) x 1) = 4
equation: y = -x + 4
