What is the solution to the system? with a graphy=-x+2y=3x-1​

Mathematics
1 answer:
Drupady [299]2 years ago
8 0

Answer:

x = 3/4

y = 5/4

Step-by-step explanation:

Step:

Substitute−x+2 for y in y=3x−1:

y=3x−1

−x+2=3x−1

−x+2+−3x=3x−1+−3x(Add -3x to both sides)

−4x+2=−1

−4x+2+−2=−1+−2 (Add -2 to both sides)

-4x = -3

x=3/4

Step: Substitute x into the original equation

y=-3/4 + 2

y=5/4

Hope this helps!!

Answer:

1. Y

2. N

3. N

4. N

Step-by-step explanation:

Let's use the second equation, since it seems to be easier to use.

To check if an ordered pair is a solution, plug it in to the equation.

1. -10+18=8 --> Y

2. 25-12=13 --> N

3. 0-9=-9 --> N

4. 35-27=8 --> N

Edit : The 4th equation doesn't work for the first equation, whereas the first one still does.

What is the slope of a line that passes through the points (61,-17) and (62,64)
4vir4ik [10]

Answer:

m = 81

Step-by-step explanation:

Recall that slope m = rise / run.

As we go from (61,-17) to (62,64), the horizontal measurement (x) increases by 1 and the vertical measurement (y) increases by 81.

Thus, the desired slope is

        81

m = ------ = 81

          1
