First you can solve for b: Subtract a on both sides and get 2b=-a+10, then divide by 2 to get b by itself and get: b=-1/2a+5
Then you can plug in this equation for b in the other: This would give you: 2a+-1/2a+5=6. Then you can use that equation to solve for a and get: 1.5a+5=6, subtract 5, 1.5a=1, divide by 1.5, a=1/1.5
Then you can plug in the value of a to solve for b.
Answer:
YAY
Step-by-step explanation:
Answer:
The equation of the line L is 
Step-by-step explanation:
we know that
The line y=7
Is a horizontal line (parallel line to the x-axis)
The slope of a horizontal line is equal to zero
A line L perpendicular to the given line must be a vertical line (parallel to the y-axis)
The slope of the line L is undefined
The line L passes through the point (2,-5)
therefore
The equation of the line L will be equal to the x-coordinate of the given point

Answer:
m = 0
Step-by-step explanation:
distribute
7 + 35m + 2m = 7 +2m
add 35m + 2m
7 + 37m = 7 + 2m
subtract 2 from 37m
7 + 35m = 7
subtract 7 from 7
35m = 0
0 ÷ 35 = 0
so technically the answer is 0
I'm not 100% sure but I do believe this is right
