Answer:

x = 91

Step-by-step explanation:

The sum of interior angles in a rectangle is 360°

x + 10 + x - 10 + x - 10 + x + 6 = 360 add like terms

4x - 4 = 360

4x = 364 divide by 4

x = 91

Answer:

x = 47

Step-by-step explanation:

So It most likely adds up to 180 degrees so.

x + 10 + x -10 + x - 10 + x + 6 = 180 (collect like terms)

4x -4 = 184 ( add 4 on both sides)

4x = 188 (divide 188 by 4)

x = 47

47 + 10 = 57 ----> x + 10

47 - 10 = 37 -----> x - 10

47 + 6 = 53 ------> x + 6

Rewrite the following equation in standard form.<br> y = 7x – 10

Bezzdna [24]

Answer:

7x - 10 -y

the y has a + sign as it is on the left hand side of the equation rewriting the equation in standard form makes the y move to the right hand side and then has a negative sign so the equation is written as 7x - 10 - y

30 points!!!

<h3>Answer: The graph is shown in the attached image below</h3>

-2x means -2*x or "-2 times x" where x is a placeholder for any number you want.

To graph y = -2x, you just need two points. Each point is of the form (x,y)

Let's plug in zero as it is often the easiest to work with.

If x = 0, then -2*x = -2*0 = 0. Notice how I replaced x with 0 and simplified.

Therefore, if x = 0, then y = 0. We have (x,y) = (0,0) as one point on this line. I have marked it as point A in the graph.

Point B is (1, -2) and it is found by plugging x = 1 into the equation to get...

y = -2x

y = -2*1

y = -2

You could find other points, but two points is enough to draw a straight line through them. The slope of this line is -2 = -2/1. The y intercept is 0.
