Answer:
7k
____________________________________________________
Step-by-step explanation:
We are trying to combine like terms with the expression: -k - ( - 8k)
We are pretty much solving it.
Solve:
-k - ( - 8k)
The "- ( -" turns into a plus sign.
So it would look like:
-k - -8k or -k + 8k
Now, you would finish solving
-k + 8k = 7k

Answer:
y=1/2x+3.5
Step-by-step explanation:
this one was a bit trickier than the previous one, but i think that that answer is correct. i did the same thing i did to solve your last problem, solved for the slope, and then made a number line and marked the points given, drew a line through the two points, and found where the line intercepted the y axis.
Answer:
the answer I think your looking for is C
Answer:
See explanation
Step-by-step explanation:
Statement Reason
1. the diagram shows segment AC with point B on this segment, then
<u>Segment addition postulate</u>
2. Given 
then
<u>Substitution property</u>
3. Simplify the equation as follows
<u>Combine like terms</u>
4. Subtract 8 from both sides
<u>Subtraction property of equality</u>
5. Divide by 8:
<u>Division property of equality</u>
