Answer:
2
Step-by-step explanation:
What you could do is fill in 2 for the equation and y would equal -3 so for the first one it's like
y= 2^2 + 5(2) -17
y= 4 + 10 - 17 which turns into y= -3
In the second y it would be something like
y= 2 - 5 which would equal y= -3
so x=2
I believe the family budget to make a one- way trip will be $140 because each gallon is $3.50. You need 20 gallons to get there which is $70. You need 20 gallons to get back which is another $70. You add both and is $140. Hope this helped.
