(-4v*3v) + (-4v*-5) + (3v*7) + (7*-5)
-12v^2 + 20v + 21v -35
-12v^2 + 41v -35
<span>x=y+2
2y=x-1
substitute </span>x=y+2 into 2y=x-1
2y=x-1
2y=y+2 -1
2y - y = 1
y = 1
<span>x=y+2
</span><span>x=1+2
x=3
answer
x = 3 and y = 1</span>
Answer:
Step-by-step explanation:
Perp. : -3/2
y + 8 = -3/2(x - 4)
y + 8 = -3/2x + 6
y = -3/2x - 2
Step-by-step explanation:
x y
−3 0
−1 −2
2 −5
6 −9 is a nonlinear
because when you plot the points given x=-3 y=0 and x=-1 y=-2 are found in the 3rd quadrant and the rest are found in the 4th quadrant.
which will not make the points linear
Hope this will help
Answer:
For no. 1:
One of the equations say that y=-7x
So plug in -7x to the other equation as y so you equation would be
-7x= -6x-7
And then, just solve for the variable:
*add -6x to both sides*:
-x= -7
*multiply both by negative one to get a positive variable*
FOR NUMBER 1, THE ANSWER IS:
x=7
Y=-7
For no. 2:
-y=x and your other equation is 3x+5y=20
Plug in x as -y:
-3y+5y=20
*simplify*
2y=20
*divide by 2 on each side to get 1 variable alone*
Y=10
FOR NUMBER 2, THE ANSWER IS:
x=-y
Y=10
