Answer:
y = 1/6x - 3 1/3
Step-by-step explanation:
y = mx + b
-4 = 1/6 (-4) + b
-4 = -2/3 + b
-4 + 2/3 = b
-3 1/3 = b
The equation is already set up for you. All you need to do is solve for x, the number of hours.
23 + 3x = 5x + 7 original equation
23 - 7 = 5x - 3x combine like terms by subtracting 7 and 3x from both sides
16 = 2x simplify
16/2 = x divide both sides by 2 to isolate x
8 = x solve for x
Therefore, the answer is 8 hrs.
Answer:
x = 2
Step-by-step explanation:
-3x - 6 = 8x + 16
8x - 3x = 16 - 6 (subtract like terms)
5x = 10 (divide by 5)
x = 2
Answer:
P, M, N and C are coplanar, because they are on the same plane.
Noncollinear, because they are not on the same line.
Hope this helps :)
3x - 2y = 1
2x + 2y = 4
Add the second equation to the first
5x = 5
2x + 2y = 4
Divide the first equation by 5
x = 1
2x + 2y = 4
Subtract the first equation from the second
x = 1
x + 2y = 3
Subtract the first equation from the second again
x = 1
2y = 2
Divide the second equation by 2
x = 1
y = 1
<h3>
So, the solution is x = 1 and y = 1 {or: (1, 1)} </h3>
