Answer:

y= 40

Step-by-step explanation:

The sum of the angle of a triangle is 180

2y+ 50 + y+10 = 180

Combine like terms

3y + 60 =180

Subtract 60 from each side

3y +60-60 = 180-60

3y = 120

Divide by 3

3y/3 = 120/3

y= 40

Answer:

y=40

Step-by-step explanation:

2y+ y+10+50=180

3y+60=180

3y=180-60

3y=12O

y=120/3

y=40

hope it helps:)

4x - 5y = 15 find the slope and y-intercept

Mazyrski [523]

Answer:

slope=4/5

y-intercept = -3

Step-by-step explanation:

first we need to rewrite the expression to

$y=mx+b$

were b is the y-intercept and m the slope

$4x-5y=15\\\\4x-5y+5y=15+5y\\\\4x+0=15+5y\\\\4x=5(3)+5(y)\\\\4x=5(3+y)\\\\\frac{1}{5}*4x= \frac{1}{5}*5(3+y) \\\\\frac{4x}{5}=3+y\\\\\frac{4x}{5} -3=3+y-3\\\\\frac{4x}{5} -3=y+0\\\\y=\frac{4x}{5} -3\\\\y=\frac{4}{5}x-3$

so there we have it

$m=\frac{4}{5} \\\\b=-3$
