Whats the math you need help with?
Answer:
x=-11
Step-by-step explanation:
the (x+14) line is half of the (17+x) line, so in order to solve this we would have to set it up like this:
2(x+14)=17+x
distribute
2x+28=17+x
x=-11

R = 18.5
Step-by-step explanation:
Answer:
Non-proportional.
Step-by-step explanation:
Membership fee of Rub-a-Dub Carwash = $100
Cost of every car wash in his visit = $12
Total payment Devon has to make in x car washes = $(12x + 100)
Graph of the relation between "total payment" and "number of visits", doesn't pass through origin. (having y-intercept = 100)
While for proportional relationship graph should pass through origin.
Therefore, this relationship is non-proportional.
