Answer:v = 9
Step-by-step explanation:
Simplifying
2(3v + 8) = 70
Reorder the terms:
2(8 + 3v) = 70
(8 * 2 + 3v * 2) = 70
(16 + 6v) = 70
Solving
16 + 6v = 70
Solving for variable 'v'.
Move all terms containing v to the left, all other terms to the right.
Add '-16' to each side of the equation.
16 + -16 + 6v = 70 + -16
Combine like terms: 16 + -16 = 0
0 + 6v = 70 + -16
6v = 70 + -16
Combine like terms: 70 + -16 = 54
6v = 54
Divide each side by '6'.
v = 9

Step-by-step explanation:
to determine cost u need to have a equation to show cost per room.and total cost of rooms
Answer:
First we need to solve the linear equation for y because we need to get the slope. Once we have the slope we need to convert it to its negative reciprocal, this means to just change the sign of the slope and flip it. The negative reciprocal is always perpendicular to the original slope.
2y = - 6x + 8
y = (-6x/2) + 8/2
y = - 3x + 4
The current slope is -3 or -3/1
The negative reciprocal is 1/3
2^2. 2 and 2. Because 2 and 2
Hello from MrBillDoesMath
Answer:
See below
Discussion:
Note the Question incorrectly shows (2n^2 +1) ^ 2. It should be (2n + 1) ^2.
So
(2 n + 1) ^2 - (2n +1) =
4n^2 + 4n + 1 - 2n - 1 = ( -1 + 1 = 0)
4n^2 + 4n -2n + (1-1) =
4(X) = 2 (2X)
Key point. The end result of the evaluation is a multiple of 2 so the result is an even integer.
Thank you,
