Answer:
1) (the red) y= 3x +2
2) (the green) y= -1x + 4
Step-by-step explanation:
Slope intercept form: y = mx + b
where m is the slope and b is the y intercept.
you can find the slope by using the formula 
, where you use two points on the line and find the space between the two.
To find the surface area of a cylinder add the surface area of each end plus the surface area of the side. Each end is a circle so the surface area of each end is π * r2, where r is the radius of the end. There are two ends so their combinded surface area is 2 π * r2. The surface area of the side is the circumference times the height or 2 π * r * h, where r is the radius and h is the height of the side.
The entire formula for the surface area of a cylinder is 2 π r2 + 2 π r h
Answer:
the pattern would be W
Step-by-step explanation:
Answer:
A
Step-by-step explanation:
Equation
2x + 3x + 8 + 7x - 2 = 90
Solution
Combine like terms on the left
12x + 6 = 90 Subtract 6 on both sides
12x = 90 - 6
12x = 84 Divide by 12
x = 84/12
x = 7
(85+90+80+100)/4 = 88.75. It's rounds off to 89
