Answer:
x+3= 2x when x = 3
3+3 = 2*3
6= 6
They are not equal when x is any other number rather than 3
Answer:
Y = 59.0°
Step-by-step explanation:
Using the cosine rule in terms of x, y and z
cosY = 
with x = 22, y = 20 and z = 18
cosY = 
= 
= 
, thus
Y = 
( ) ≈ 59.0° ( to the nearest tenth )

Good luck!!!!!!!!!!
Supplementary = equal to 180 degrees.
We can set up an equation.
2x + x = 180
Combine like-terms:
3x = 180
Divide both sides by 3 to isolate the x.
x = 60.
So one angle is 60 degrees and since the other one is twice of x, it is 120 degrees. If you add 120 and 60 degrees, you should get 180 degrees.
Nevertheless, the measures of the angles are 60 and 120 degrees.
Answer:
C. Linear
Step-by-step explanation:
both the slope and y-intercept is positive and if you make the graph their linear
