Please help me with this equation

Form the equation will be in: y = mx + b

Equation: y = 25x + 504

3.

m = the cost per hour for labor

x = the number of hours of labor

b = the cost of parts

y = the total cost of parts and labor, or the total cost of the repair (both are the same)

4.

y = 25(5) + 504

y = 125 + 504

y = $629

Mr. Conner had to pay $629 if it took them 5 hours to repair his car

Hope this helps!! :)

y = mx + b

y = total cost

m = money spent per hour

x = each hour

b = start cost

y = 504 + 25(5)

629 = 504 + 125

step-by-step explanation:

thats the first half

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.
