Answer:

y = 2

x = 50

Step-by-step explanation:

We can first find y by doing 12y+5 = 18y-7 since vertical angles are always congruent.

We want to combine like terms so we subtract 12y from both sides (what you do on one side needs to be done to the other) and we get 5 = 6y-7 and now we add 7 to both sides to get 12 = 6y.

Like I said we did this because we combine like terms!!!

Now we want to isolate the y and we do this by dividing 6 from both sides which lets us get 2 = y

Now that we know what y is we can plug it into any of the equations using y.

I plugged it into the top right equation cause it was easier.

12(2)+5

24+5

29!

That angle is 29!

Now that we know that we can begin solving for x.

The equation that has x + 29 make 180 degrees because it is a straight line so we use this to solve for x!

3x+1+29=180 (We want to start combining like terms now)

3x+30=180(Subtract 30 from both sides)

3x=150 (Isolate the x by dividing 3 from both sides)

x=50!

We can prove this is right by inserting x into it's expression. That tells us the angle is 151. Now we add 151+151+29+29 and we get 360!

Directions: Graph each equation by using the y-intercept and slope( make sure too show your work)
vova2212 [387]

Given:

The equation of a linear function is:

y=-\dfrac{2}{3}x-1

To find:

The y-intercept and slope of the given equation, then draw the graph of the equation.

Solution:

Slope intercept form of a line is:

y=mx+b             ...(i)

Where, m is the slope and b is the y-intercept

We have,

y=-\dfrac{2}{3}x-1        ...(ii)

On comparing (i) and (ii), we get

m=-\dfrac{2}{3}

b=-1

Therefore, the y-intercept is -1 and the slope of the line is -\dfrac{2}{3}.

It means the graph intersect the y-axis at point (0,-1) and having slope -\dfrac{2}{3}. So, the graph of the equation is shown below.
