Answer: x=4/31y + -18/31

Step-by-step explanation:

Let's solve for x.

2y=−x+(8)(4)x−2y+18

Step 1: Flip the equation.

31x−2y+18=2y

Step 2: Add 2y to both sides.

31x−2y+18+2y=2y+2y

31x+18=4y

Step 3: Add -18 to both sides.

31x+18+−18=4y+−18

31x=4y−18

Step 4: Divide both sides by 31.

31x/31 = 4y-18/31

Answer: x=4/31y + -18/31

1) Identify the slope of the given line
adell [148]

ok so here we go:

1) (-6,-2.5),(-4,-3)\ m= -0.25 or  -\frac{1}{4}

2 )y=-0.25x-4 so the answer is (0, -4) or -4

3) y=\frac{3}{2}x+1 m=\frac{3}{2}

4) y=[tex]\frac{3}{2}x+1[tex] so the answer is (0, 1) or 1

Give the coordinates of Point P without using any new variables. <br><br> (Please show your work.)
poizon [28]

Answer:

(a-b, c)

Step-by-step explanation:

The midpoints of the two diagonals are the same, so we have ...

(P + (-a, 0))/2 = (O +(-b, c))/2

Multiplying by 2 and subtracting (-a, 0), we get ...

P = (0, 0) +(-b, c) -(-a, 0)

P = (a-b, c)
