The sum of angles in triangle is equal to 180 degrees, so
<R =180-56-30
<R=94
Answer:
you switch 8x and 4y by subtracting 8x to 4y + 16 and substracting 4y to 8x.
This gives you the equation -4y = -8x+16
Then you divide each side by -4
To give you your slope-intercept form which is y = 2x-4.
Answer:

Step-by-step explanation:
Simplify the expression and you will get this.
