you would add 3y+5y and get 8y=-20
then the slope would be 8/1 and your y-intercept would be -20
Answer:
y=-x-9
Step-by-step explanation:
y-y1=m(x-x1)
y-0=-1(x-(-9))
y=-1(x+9)
y=-x-9
Answer:
140,150
Step-by-step explanation:
The sum of the angles in a polygon is
180(n−3)
For a pentagon, this equals 540. Since the first 3 angles add up to 240, the remaining 2 angles must add up to 540−240=300∘
7*63
(7*60)+(7*3) HOPE THIS HELPED
