The answer is for the value of y-coordinate is -5
You can use Substitution to solve this problem:
4x-y=20
-y=-4x+20
y=4x-20
Now you have two equations, and you use the first one to substitute into the second one.
y=4x-20 and -2x-2y=10
-2x-2(4x-20)=10
-2x-8x+40=10
-10x+40=10
-10x=-30
-x=-3
x=3
Now that we have figured out what x is, we can substitute x in to one of the equations to figure out y.
4x-y=20 x=3
4(3)-y=20
12-y=20
-y=8
y=-8
<em><u>So your answer would be x=3 and y=-8</u></em>
Answer:
B
Step-by-step explanation:
Notice that if we divide our given equation (2x - 4 = 6) by 2 from both sides, we get:
(2/2)x - (4/2) = (6/2)
x - 2 = 3
Now, notice what happens if we multiply this by -3:
-3 * (x - 2) = 3 * (-3)
-3 * x + (-3) * (-2) = -9
-3x + 6 = -9
This matches B.
Hope this helps!
Since this is numberical data graph it as a line graph
Your question has been heard loud and clear.
Well -(-5)=5
5/-5/= -5
/-5/5= -5
So basically , the statement is false because -5(-5) not equal to -5/-5/
Thank you
