Answer:
The main difference is that one has the equal sign before it while the other has it after.
You can decide which one to use based on each individual expression. If you are still simplifying, put it like this: ()=. If you are done simplifying and have your answer and are using a parenthesis, put it like this: =()

Answer:
B) n=-2
Step-by-step explanation:
First, distribute.
7(1+4n)-5=-38+8n
7+28n-5=-38+8n
Combine like terms.
2+28n=-38+8n
To make solving the equation easier, subtract 8n first, so there isn't a negative variable.
2+28n=-38+8n
<u>-8n -8n</u>
2+20n=-38
Subtract 2 on both sides.
2+20n=-38
<u>-2 -2</u>
20n=-40
Divide by 20 on both sides.
20n=-40
<u>/20 /20</u>
n=-2
Hope this helps!! Have a wonderful day :3
we are given with two points: (-8,8) and (0,1). in this case, we are asked for the equation of the line connecting the two. we first solve for the slope that is (8-1)/(-8-0) equal to 7/-8 or -7/8. We substitute to the point-slope form equation y-y1 = m (x-x1) that is y - 1 = -7/8 * x ; y = -7/8 x + 1
