Answer:
<u>x=6</u><u> y=16</u>
Step-by-step explanation:
I will use elimination
y=2x+4
y=2x+x-2
*3 y=2x+4 3y=6x+12
*2 y=3x-2 2y=6x-4
3y=6x+12
- 2y=6x. -4
<u>y=16</u>
16=2x+ 4
-4 -4
12= 2x
/2 /2
<u>6=x</u>
Your answer should be C.
Let me know if you have any questions :)

Answer:
x=-4 and x=-16
Step-by-step explanation:
<em> 24 mph</em>
- <em>Step-by-step explanation:</em>
<em>Hi there ! </em>
<em>Vm = 21mph</em>
<em>V1 = 18mph</em>
<em>V2 = ?</em>
<em>Vm = (V₁ + V₂)/2</em>
<em>2Vm = V₁ + V₂</em>
<em>V₂ = 2Vm - V₁</em>
<em>replace Vm ; V₁</em>
<em>V₂ = 2×21mph - 18mph</em>
<em>= 42mph - 18mph</em>
<em>= 24 mph</em>
<em>Good luck !</em>
