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)
Answer:
○ -1
Step-by-step explanation:
Looking closely at this piecewise function, when the line on the left-hand side intersects at -3 = y, x is -1.
i hope this work for you
Answer:
4
Step-by-step explanation:
As I stated, the formula of the area of a triangle is LW/2.
Meaing all you have to do is 4x2/2.
This number would be 24. So 21 own football boots, 16 own a football and there are 24 children in the class. not good at math so yeah
