Answer:
y=-4x-6
Step-by-step explanation:
y=mx+b, where m is the slope and b is the y-intercept
Slope is given as -4, so:
y=-4x+b
To find b, sub in the point we were given (-2,2):
2=-4(-2)+b
2=8+b
b=2-8=-6
So we have: y=-4x-6
The amount of the paint that Ellis needs to paint all the surfaces of the 12 fenceposts will be 226.08 square feet.
<h3>What is a cylinder?</h3>
A cylinder is a closed solid that has two parallel circular bases connected by a curved surface.
Ellis is painting wooden fenceposts before putting them in his yard. They are each 6 feet tall and have a diameter of 1 foot. There are 12 fenceposts in all.
The amount of the paint that Ellis needs to paint all the surfaces of the 12 fenceposts will be
The area of the one fence post will be
Area = πdh
Area = 3.14 x 1 x 6
Area = 18.84 square feet
Then the paint for 12 fence posts will be
Total area = 12 x 18.84
Total area = 226.08 square feet

Answer:
The 3rd one again
Step-by-step explanation:
(a+−2)(8
+−5a+3)
=(a)(8)+(a)(−5a)+(a)(3)+(−2)(8)+(−2)(−5a)+(−2)(3)
=8
−5+3a−16+10a−6
=8−21+13a−6
hope this helped:)
