If a line is perpendicular to -2x, the slope has the opposite reciprocal. In this case, the opposite reciprocal of -2x is 1/2x. Then you plug in the coordinates in the y = mx + b format:
5 = 1/2 (-2) + b
Then you solve for b and you should get b = 6
Answer:
50%
Step-by-step explanation:
I assume you're looking for the value of x?
Combine like terms: 8x+5x+2x-11+6=180 -> 15x-5=180
Add 5 to both sides: 15x=185
Divide both sides by 15: x=12 1/3
So x is 12 1/3 or 37/3

Answer:
480 inches^3
Step-by-step explanation:
The volume of a Prism is: Bh
B= length of the base
h= height of the lateral face
(8*10)4
320 inches^3
So for the 2nd figure on top you do the same.
This time you divide by 2.
So it's 160 inches^3.
Add up you get a sum of 48- inches^3.
Or 480 cubic inches.
