Answer:
I think sine hope it is helpful to you
So if you're solving that equation to get v by itself you need to combine your like terms which are -16 and 1. -16+1= -15 so you are left with 4v-15=3. Now you would add 15 to both sides. -15=15 get canceled out. So you add 3+15=18. Then 4v=18
Y/x = 9/12 = 3/4
so
y = (3/4)x . . . . . . both x and y in dollars.
34 = q + n
6.1 = .25q + .05n
-1.7 = -.05q - .05n
6.1 = .25q + .05n
4.4 = .2q
q = 22
22 of the coins are quarters.
From the intervals from (-2,0) and (4,7) I am not sure if you are required to use (,) or [,] but I will change my answer if needed.
Thank you!
