N=m-2
m-2n=8, using n from above in this equation yields:
m-2(m-2)=8 perform indicated multiplication
m-2m+4=8 combine like terms on left side
-m+4=8 subtract 4 from both sides
-m=4 divide both sides by -1
m=-4
So the correct answer is A) m=-4
"The number 39 is equal to"
39=
"thirteen subtracted from an unknown number"
r-13
Putting it together you have:
39=r-13
Answer:
y=2x+7
Step-by-step explanation:
The slope of the new line is 2 because that is the opposite of -1/2
To find the equation of the line, plug the points (-2,3) into point-slope form:
y-y1=m(x-x1).
y-3=2(x+2)
Multiply (x+2) by 2 and simplify to get the final answer.
y-3=2x+4
y=2x+7
