Answer:
For #6, it is 81 degrees, and for #8, it is 100 degrees.
Step-by-step explanation:
For #6, it is on the opposite side, so 81 degrees
For #8, it is also on the opposite side, so 100 degrees
Whenever there are parallel lines going horizontally, the angles measure the same on opposite sides, and to find the measure of an angle next to another angle, subtract it from 180.
Equation 1: x² + y = 7
Equation 2: 3x + 7 = 9
Use Equation 2 to solve for "x" and plug in "x" into Equation 1 to solve for "y".
3x + 7 = 9
3x = 2
x = 
*********************************
x² + y = 7
()² + y = 7
+ y = 7
y = 7 -
y = 
-
y = 
Answer: (, )
Y=mx+b *thats the equation for graphs like that*
