Answer:
Square root of 4 is 2
so 1+
=4
frac{[1+sqrt{2x-1]}^2 }{4}=3
so 1+sqrt{2x-1]}^2=12
so 1+sqrt{2x-1}=V12
sqrt{2x-1}=V12-1
2x-1=(V12-1)^2=12-2V12+1=13-2V12
2x=13+1-2V12
2x=14-2V12
x=7-V12
x=7-2V3

Step-by-step explanation:
Answer:
C) y+7 = -2/3(x-1)
Step-by-step explanation:
You have to change the signs of the x and y coordinates...

y = -7 is the same a (y+7)
Answer:
Marcus will own 380 songs after a year.
Step-by-step explanation:
the equation would look like
![N=15m+200](https://tex.z-dn.net/?f=N%3D15m%2B200)
you
then put 12 in for (m)
n=15(12)+200
n=180+200
n=380
Marcus will own 380 songs after a year.
