12 cups because there are 2 cups in a pint and 2 pints in a quart
You would have to add x1 + x2 and divide by 2. do the same with y1 and y2.
(1/2,-1/2)
Answer:
Length of AB = Length of C′D′
Length of CD = Length of B′C′
Step-by-step explanation:
Not sure but I think
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
