Answer:
Step-by-step explanation:
-10 and 9
-10×9=-90
-10+9=-1
-2-w is equivalent to -24 - 12w all you have to do is simplify the expression!
It should be eight if I remember correctly
First question:
1. Set equations equal to each other so 5x-9=2x+6
2. Put x's on one side so that 3x=15
3. Divide by 3 so that x=15
4. Substitute 15 in for x so that y=2(15)+6
5. Solve for y so that y=36
6. Thus the equations intersect at (15,36)
Second question:
1. Since for lines y=mx+b, and m=slope=3 you only need to write an equation with slope 3
2. y=3x+b, b can be any number
