Answer:

x = 48

Step-by-step explanation:

We now that supplementary angles (as is the case for a straight line) add up to 180 degrees.

3x - 12 + x = 180

If x varies directly with y and x = 3.5 when y = 14, find x when y = 18.
maks197457 [2]

Answer:

x = 4.5

Step-by-step explanation:

there's definitely other ways to solve this, but I used a proportion.

\frac{3.5}{x} = \frac{14}{18}

Then you can make this equation:

14x = 3.5 * 18

I solved for it and got 4.5 .

What would the sum of -18-(-12) be?
Mademuasel [1]
-18-(-12)=-6 
Since there is two negative sign, it turns into positive meaning the -12 becomes positive 12 and the -18 stays same. So -18+12=-6 because 18 is bigger than 12 and it's negative so the final answer should be negative. 
Hint: when you see two negative sign just turn them into plus sign.

9. Write an equation for the line that is parallel to the given line and that passes through the given point.
timurjin [86]

Answer:

  y -11 = 2(x -3)

Step-by-step explanation:

The slope of the given line is the x-coefficient: 2. The parallel line will have the same slope.

When you know the slope and a point on the line, it is convenient to use the point-slope form of the equation of a line:

  y -k = m(x -h) . . . . . . line with slope m through point (h, k)

Your line's equation is ...

  y -11 = 2(x -3)
