If 21 is added to (+ 21) a number (x) the result (=) is 40 less than (- 40) twice the number (2x)

x + 21 = 2x - 40   Add 40 to both sides
x + 61 = 2x           Subtract x from both sides
      61 = x             Switch the sides to make it easier to read
       x = 61

PLEASE HELPP!!!!!<br>what is the slope of the line?<br><br>-3<br><br>1<br><br>0<br><br>undefined

Answer: -4

The formula for slope is rise/run. This means that between two points, you have to see the distance going up and down/ left and right.

Looking at points (0,-1) and (3,-1), you can see that the height difference is 4 units. This means that the rise is 4.

rise/run

4/run

Left and right, the difference is only one unit.

4/run

4/1

4

This graph is also negative, so let’s add that in.

-4

This is your answer! I know it wasn’t one of the options you provided, but I’m pretty sure that this is the answer.

Hope this helps comment below for more questions :)

In the diagram below, xy and yz are tangent to O. What is the measure of angle y
Tatiana [17]

If we draw in  OX, OY, OZ we have two congruent right triangles, right angles at the tangent points.

We know XOZ is 132 degrees, which is the meaning of the arc measure

So YOX is half that, 66 degrees.

That leaves 180 - 90 - 66 = 24 degrees for OYX

Angle Y aka XYZ is double that, 48 degrees.

Answer: C
