Answer:
x= 13/22
Step-by-step explanation:
you can substitute y= 34 x on the second equation
34x = -54x +52 add 54x to both sides
34x +54x = -54x +54x +52
88x = 52 divide both side by 4
22x = 13 divide both sides by 22
x= 13/22
2x^2-y
Plug in the values.
2(3)^2-(-2)
2(3)^2+2
Exponents first.
2*9+2
18+2
20
The answer is 20.
I hope this helps!

Answer:
Growth and 108.5%
Step-by-step explanation:
<h2><em>ts = 4x - 7
</em></h2><h2><em>
</em></h2><h2><em>sv = 5x - 15
</em></h2><h2><em>
</em></h2><h2><em>If s is the midpoint of ts and sv, then ts = sv, so
</em></h2><h2><em>
</em></h2><h2><em>4x - 7 = 5x - 15
</em></h2><h2><em>
</em></h2><h2><em>5x - 4x = 15 - 7
</em></h2><h2><em>
</em></h2><h2><em>x = 8
</em></h2><h2><em>
</em></h2><h2><u><em>Not 100% sure </em></u></h2>
