Answer:
x=-1, y=5. (-1, 5).
Step-by-step explanation:
y=-2x+3
y=-7x-2
-------------
-2x+3=-7x-2
-2x-(-7x)+3=-2
-2x+7x+3=-2
5x+3=-2
5x=-2-3
5x=-5
x=-5/5
x=-1
y=-2(-1)+3=2+3=5
Answer:
It is a proportional relationship
Step-by-step explanation:
To see if multiple ratios are proportional, you could write them as fractions, reduce them, and compare them. If the reduced fractions are all the same, then you have proportional ratios.The equation that represents a proportional relationship, or a line, is y=kx, where k is the constant of proportionality.
Hope this helps
the constant of proportionality is 2
Answer:
Since the two angles are across from each other that tells us that they are equal in length, so we want to set them equal to each other
3x+50=6x-10, Now we want to solve it like a normal equation, get x by itself
First add 10 to each side
3x+50+10=6x-10+10
3x+60=6x
Now we want to subtract 3x from each side
3x-3x+60=6x-3x
60=3x
Now divide both sides by 3
60/3=3x/3
20=x
x=20

Answer:
The answers provided aren't reasonable for this graph.
Step-by-step explanation:
The graph's y-intercept is -2, since that is the point where the line intersects the y-axis. The slope is 3x, because the distance from one point to the next is 3 up, 1 right. So the equation for the graph is y = 3x - 2.
