Sanaiah can work at most 20 hours next week, but she needs to earn at least $200. Her babysitting job pays $12.50 an hour and her dog walking job pays $10 an hour. Identify the variables and then write a system of equations to represent the constraints on Sanaih's work time and income. Remember to include common sense constraints. You will have 4 separate inequalities for your answer.

(x+3)(x+7)

plese mark mde brainliest!

guess at question:

a vertical line intersects the graph of g(x,y) = 0 at two points. what conclusion follows about the function f(x) implicitly defined by g(x,f(x)) = 0?

the domain of f(x) cannot include the x coordinate of any such vertical line.

informally, f(x) is not a function, and

g(x,y)=0 cannot be solved for y uniquely.

the relation r = {(x,y) such that g(x,y) = 0} is a function if

for all (a,b) ∊ r and (c,d) ∊ r, a=c implies b=d.

step-by-step explanation:

you just switch the numbers basically so it would be 3/17
