M = 4, 1. 5=5m+2m-23 2. 5=7m-23 3. 28=7m 4. m=4. The first step is just me rewriting the problem so that like terms are right by each other. On the left side I added the like terms, 5m and 2m. That equals 7m. Now, looking at the second step. To get rid of the -23 on the left side, we add 23 to it which cancels it out. We have to add 23 on the other side too. So, 5+23 is 28. This brings us to step 3. 7m divided by 7 is M. And 28 divided by 7 is 4. This leaves us with the answer m=4.

1 = 51

2= 61

3= 29

Step-by-step explanation:

1) 61+68= 129

180-129= 51

2) 61 is across it so they have the same number

3) 61 +90= 151

180-151= 29

Is y=3x+4 parallel or perpendicular

Sauron [17]

Answer: $y=3x+4$ is parallel to $y=3x+7$

Step-by-step explanation:

<h3> The complete exercise is: "Is $y=3x+4$ parallel, perpendicular or neither to $y=3x+7$ ?"</h3><h3 />

The equation of the line in Slope-Intercept form is:

$y=mx+b$

Where "m" is the slope of the line and "b" is the y-intercept.

First, in order to solve this exercise it is important to remember that, by definition:

1. The slopes of parallel lines are equal.

2. The slopes of perpendicular lines are negative reciprocal.

In this case, you have the following line given in the exercise:

$y=3x+4$

You can identify that "m" and "b" are:

$m=3\\b=4$

And the other line provided in the exercise is this one:

$y=3x+7$

So, you can identify that:

$m=3\\b=7$

As you can notice, the slopes of both lines are equal; therefore, you can conclude that those lines are parallel.
