Answer:
x=18
Step-by-step explanation:
2/3x=12
2/3x=36/3 (simplified)
3* 2/3x=3* 36/3 (gets rid of denominator)
2x=36
(2x)/2=36/2 (getting rid of 2)
x=18 (answer by isolatinf variable)
Answer:
x = -1, and y = -2, giving you the answer (-1, -2)
Step-by-step explanation:
In the second equation, we're told that y is equal to 2x. With that, we can replace "y" in the first one with "2x", giving us:
-4x - 2x = 6
-6x = 6
x = -1
Now that we know the value of x, we can simply plug it into the first equation to find y:
-4x - y = 6
-4(-1) - y = 6
4 - y = 6
-4 + y = -6
y = -6 + 4
y = -2
So x = -1, and y = -2
The correct answer is Choice D.
The equation y = kx is a proportional graph. It means that you multiply x by a number and you have k.
The point (0, 0) will always be on the graph, because no matter what K is, if you are multiplying by 0 for x, you will get 0 for y.
