Hey there!!

To check whether x= -4, let's solve the equation.

Given:

3x+7 = x-1

Subtracting 2x on both sides:

2x + 7 = -1

Subtracting 7 on both sides:

2x = -1-7

2x = -8

Dividing 2 on both sides:

x = -8/2

x = -4

<u><em>Yes, x is -4. </em></u>

<u><em>Hope it helps!</em></u>

Answer:

Yes

Step-by-step explanation:

You multiply 3 by -4 to get -12, then add 7 to make the left side of the equation -5. On the right side, all you have to do is do -4 minus 1, which is -5. That being said, yes x=-4

So all the angles of triangle add up to 180 degrees. So you add up the the two other sides and subtract 180 by the answer.

61 + 58 = 119

180 - 119 = 61

So, you’re answer would be 61 degrees. Hope that helped :)

Enter the equation of the line in the form y=mx where m is the slope.Immersive Reader
kari74 [83]

Answer:

y = 1/2x

Step-by-step explanation:

The slope is the rise (up) over run (left or right depending on if the number is negative) between points. So the next point on the graph is up 5 and over 10. this simplified is 1/2. Then you put this into y=mx which is y=1/2x
