11 1/2 is your answer good luck!
Answer:
A
Step-by-step explanation:
Lateral surface area = surface area - bases
2(8(11) + 8(5)) =
256 <--- Lateral Surface Area
The bases have areas of 11*5 = 55
Multiply that by 2 and add to 256
256 + 110=
366 <---Surface Area
I first found the slope of the line graphed. So i took 2 points and found the slope. They were (2,0) and (0,-3). The slope was 3/2. I then flipped it and added a negative because your looking for the perpendicular line. That was -2/3.
I took the formula y1-y=m(x1-x) and put in -2/3 as m and y1 as 2 and x1 as -1. You plug those into the equation and solve for y.
I got B for the answer
Hope this helps!
Answer:
y = 3x + 5
Step-by-step explanation:
slope:
11 - (-1) / 2 - (-2) = 12/4 = 3
slope intercept form is y = mx + b, so right now you have m = 3:
y = 3x + b
now, since you know x = -2 and y =-1 is a solution, you can plug those values in:
-1 = 3 * -2 + b
-1 = -6 + b
5 = b
This means the equation is y = 3x + 5
Answer:
b=-1
Step-by-step explanation:
10(1+3b)=-20
1+3b=-2
3b=-3
b=-1
