Y-intercept is what the y is when x is 0
(0,15) when x is 0, y is 15.
y-intercept is 15.
Roc: the x is going up by 4, the y is going up by 8
Always divide the difference for y by the difference for x
8 ÷ 4 is 2
ROC is 2
Answer:
150
Step-by-step explanation:
The sum of the angles of a quadrilateral are 360. Let x be the unknown angle
30+70+110+x = 360
Combine like terms
210 +x = 360
Subtract 210 from each side
210+x-210 = 360-210
x = 150
Answer:
B
Step-by-step explanation:
Given endpoints (x₁, y₁ ) and (x₂, y₂ ) then the midpoint is
( , )
Here (x₁, y₁ ) = (2, 3) and (x₂, y₂ ) = (10, 3) , then
midpoint = ( , ) = ( , ) = (6, 3 ) → B
Given that it would take 4 hours for first pipe to fill half, and 4.5 hours to fill half with other pipe u would then do 4+4.5=8.5, then 8.5/2=4.25
