Answer: idk
Step-by-step explanation: I don’t know because there is no question just a word problem without the question involved
You would need to make them eliminate so I would multiply the entire first one by 2.5 to make the X's cancel out. So you would end up with -5X+7.5Y=17.5. The X's would cancel and you would be left with 15.5Y=15.5. So Y=1. Then replace Y into one of the equations. I'm going to use the top again. -2X+3(1)=7. Subtract 3 from both sides to get -2x=4. Divide both sides by negative 2 to get X=-2. So the solution would be (-2,1)
Hi again
For m = -6
Evaluate:
m² + 5m - 1
(-6)² + 5(-6) - 1
36 - 30 - 1
= 6 - 1
= 5
Let me know if you have any questions. As always, it is my pleasure to help students like you!
The answer is -11/2, 9/2
Explanation
You have to rewrite the absolute value equation as two separate equations.
2x+1=10
2x+1=-10
Then you solve for X in each equation.
2x+1=10 would give you 9/2
2x+1=-10 would give you -11/2
So your final solutions would be x1= -11/2 x2= 9/2
