Answer:
Not quite sure what you're meant to solve for, but my solution is below.
Step-by-step explanation:
The square root of a value squared is the absolute value of that value, because squaring removes all negatives. Therefore:
![\sqrt{(y+2)^2}=c](https://tex.z-dn.net/?f=%5Csqrt%7B%28y%2B2%29%5E2%7D%3Dc)
![\mid y+2\mid=c](https://tex.z-dn.net/?f=%5Cmid%20y%2B2%5Cmid%3Dc)
![\mid y\mid =c-2](https://tex.z-dn.net/?f=%5Cmid%20y%5Cmid%20%3Dc-2)
Hope this helps!

Answer:
The x-coordinate of the solution is x=3
Step-by-step explanation:
we have
------> equation A
------> equation B
Solve the system of equations by substitution
Substitute equation B in equation A and solve for x
![x-1=-x+5](https://tex.z-dn.net/?f=x-1%3D-x%2B5)
![x+x=5+1](https://tex.z-dn.net/?f=x%2Bx%3D5%2B1)
![2x=6](https://tex.z-dn.net/?f=2x%3D6)
![x=3](https://tex.z-dn.net/?f=x%3D3)
Find the value of y
------>
The solution of the system of equations is the point (3,2)
therefore
The x-coordinate of the solution is x=3
Answer:
95 nickels 19 dimes
Step-by-step explanation:
d=dimes
5d=nickels
0.05(5d) + 0.10(d) = 6.65
0.25d + 0.10d = 6.65
0.35d=6.65
Divide by 0.35
d= 19 (19 coins)
19 dimes =$1.9
6.65-1.9= $4.75
Nickels=$4.75
4.75/0.05 = 95 coins
19*5=95
114 coins in total
19*0.10 = 1.9
95*0.05=4.74
4.75+1.9= 6.65
