Help Me! ASAP! I'll Mark The Brainliest! Ernesto brings his dog to training classes. the equation -60x+2y-120=0 relates y the total. cost of a pets training and x, the number of classes taken. Ernesto states that the y-intercerpt of the line represented by the equation is 30. Is he correct? Explain your reasoning.

ok put into y=mx+b form

2y=60x+120

y=30x+60

so we know 60 is the y-intercept so he is not correct

if u want more:

-60x+2y-120=0 add 60x

2y-120=60x add 120

2y=60x+120 divide by 2

y=30x+60

Hope this helps plz hit the crown :D

yx = 36

step-by-step explanation:

cos f = opposite side/ hypotenuse

cos f = yw / yx

we know cos f = 4/9 and yw =16

4/9 = 16/yx

multiply each side by yx

4/9 yx = 16/ yx * yx

4/9 yx = 16

multiply each side by 9/4

9/4 * 4/9 yx = 16 *9/4

yx = 36
