Answer:

1. -2, 2. -23, 3. 25

Step-by-step explanation:

1. -2+5x8/-12=  step 1: add -2+5

-2+5=3       step 2: 3(8)

3x8= 24     step 3: 24/-12

24/-12= -2

2. -2(9-4)+3=?  step 1: combine like terms -2(9) and -2(-4)

-18-8+3=?    step 2: combine like terms

-26+3=?      step 3: combine like terms

-23=?

3. 2x + 130=180    step 1: -130 on both sides

   2x = 50              step 2: /2 on both sides

    x = 25

Where does the point (0, - 3) lie?
gregori [183]

An ordered pair is written like this, ( x, y ). In this case x = 0 and y = -3. On a graph the vertical line is the y-axis and the horizontal line is the x-axis. The origin is point ( 0, 0 ). To the left of the origin on the x-axis is the negative number line and to the right is the positive number line. On the y-axis, south of the origin is the negative number line and north is the positive number line. When you plot a point on a graph you do x first, so if x equals 1, you would move one right, -1, one left. IF y were to equal 2 then from the place where you are on the x-axis, 1, you would move two up, -2, two down. In this case x = 0 so you would stay at the origin, and y = -3 so you would move 3 down. So ( 0, -3 ) would lie negative y-axis. The answer is D.
