Answer:
x = 40
Step-by-step explanation:
If you add the total of 3 angles in a STRAIGHT line, you have to get 180 in total.
So, x = 180 - ( 80 + 60 )
= 180 - 140
= 40
The way to answer this problem given different points and different equations in the choices is to do substitution and trial and error. In this regard, we substitute for example 4 to x in the equations and check which of them yields 89. The answer is D.
Answer:
The answer is Congruent: (x,y)-(x+5,y), (x,y)-(x,-y),(x,y)-(-x,-y) Not Congruent: (x,y)-(5x,5y)-(x,y)-(0.5x,0.5y). Or the answer for congruent is answer choice 1, 4 and 5. Not Congruent is answer choice 2 and 3.

Answer:
x = 1
y = -3
Step-by-step explanation:
if y = x - 4
then reorganise the first equation
4 (x - 4) = 9x -21
4x - 16 = 9x - 21
5 = 5x
x = 1
