Tom starts lawn mowing business before he can begin he purchases a new lawnmower each weekend he mows the same number of lawns and earns the same amount of money write and equation to show how much money he's earned any week

B. y = 60x - 150

Step-by-step explanation:

From week 1 to week 2 he earn -30 - (-90) = $60

From week 2 to week 3 he earn 30 - (-30) = $60

This profit is repeated every week, and 60 represent the slope of the line that relates y and x.

Then, the y value for week 0 is -150, in this way:

From week 0 to week 1 he earn -90 - (-150) = $60

the same value as before is satisfied. -150 is the y-intercept of the line (the y value when x = 0). Therefore, the equation is:

y = slope*x + y-intercept = 60x - 150

step-by-step explanation:

. your answer will contain x - and y -terms. (1 point) x ( ¿¿ 2 − 7 ) 2 +( y 2 − 9 ) 2 √ ¿ 12. what is the distance from the directrix (the crocodile river) to the point ( x , y )? write this equation. your answer will contain a y -term.

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.
