Answer:

2x + 8

Step-by-step explanation:

Don't worry, this is simple! Add up the common terms.

For example, you can't add up 2x and 5, because 2 is being multiplied by a variable.

So combine the x terms: 2x

And the numerical terms: 8

Combine 2x and positive 8.

2x + 8

The given line passes through the points (-2,-4) and (2,2) What is the equation, in point-slope form, of the line that is parall

Morgarella [4.7K]

Answer:

$(y-1)=\frac{3}{2}(x+3)$

Step-by-step explanation:

The point slope form of a line is $(y-y_1)=m(x-x_1)$ where $x_1=-3\\y_1=1$ . We write

$(y-1)=m(x--3)\\(y-1)=m(x+3)$

Since the line is parallel to the line shown it will have the same slope. To find m, count the slope from each marked point on the graph. Count the rise then the run and create a fraction rise/run. The slope is 6/4 which simplifies to 3/2. Now substitute it for m.

$(y-1)=\frac{3}{2}(x+3)$

Answer:

x=45

Step-by-step explanation:

This is a triangle so it interior degrees will add up to 180.

Since Line AC is tangent to Circle O at point c, Point C measures 90 degrees.

We can find OAC by using the triangle interior theorem,

$45 + 90 + x = 180$
