Answer:
no 5 7 6
Step-by-step explanation:
If they have the same charge
x+x+x+x+x+x+x=-42
7x=-42
x=-6
so to check our answer
-6-6-6-6-6-6-6=-42
-12-12-12-6=-42
-24-18=-42
-42=-42
Answer:
Step-by-step explanation:
2.5 x
* 3.7 x 
add the expoents, and multiply the coefficients
2.5 * 3.7 =9.25
= 
9.25 x 
Answer: x=21
Step-by-step explanation:
To solve for x you must first combine you like terms on each side of the equal sign. So you problem will become 8x+1=22+7x. Then get your x on one side and your numbers on the other by taking the one away from the right side and 1 away from 22. Then take away 7 from the left side to cancel it out. Then take 7x away from 8x to leave you with x. making your answer x=21
Answer:
I'm not sure if your asking for an entire equation but the points for the vertex would be (-3,-4)
