Answer:
4:12=5:15
in propotion form
4/12=5/15
Step-by-step explanation:
Solve for y
-7y = -2x + 8
y = (2/7)x - 8/7
A parallel line has the same slope as the given line. The slope of the given line is (2/7)
y = (2/7) x + b Now we have to find b using (-1,-1). When x = - 1 so does y
-1 = ( 2/7)*(-1) + b
-1 + 2/7 = b
b = - 5/7
The line is
y = (2/7)x - 5/7
One Solution at point (3, -2)
Answer:
-3
Step-by-step explanation:
i think it might be-3 because a negative and a negative equals a positive
From these -Tx+y=S. If -T=Q/R, then y=-Qx/R+S, so Ry=-Qx+RS, Qx+Ry=RS=S.
If R is not equal to 1, or S is non-zero, the equations are inconsistent, so there would be no solutions.
If R=1 there are an infinite number of solutions given by Qx+y=S, or y=S-Qx or y=S+Tx.
If S=0, Qx+Ry=0 or y=-Qx/R or y=Tx.
