y = x² - 4x + 8
4x + y = 12
4x + y = 12
4x + (x² - 4x + 8) = 12
x² + 4x - 4x + 8 = 12
x² + 8 = 12
- 8 - 8
x² = 4
x = ±2
4x + y = 12
4(2) + y = 12
8 + y = 12
- 8 - 8
y = 4
4x + y = 12
4(-2) + y = 12
-8 + y = 12
+ 8 + 8
y = 20
(x, y) = (2, 4) and (-2, 20)
Answer:
x=5
Step-by-step explanation:
4(3x+2)=68
Divide each side by 4
4/4(3x+2)=68/4
3x+2 =17
Subtract 2 from each side
3x+2-2 = 17-2
3x = 15
Divide each side by 3
3x/3 = 15/3
x =5
The value of x would be 60 degrees
explanation
===============================
the triangle has one missing angle that would be congruent to x since they are corresponding angles which means they are congruent.
We know that the triangle has to add up to 180 degrees. We add the 2 angles and get 120 degrees. We subtract 120 degrees from 180 to find the 3rd missing angle that is congruent to x degrees. 180-120=60 degrees. If 60 degrees is corresponding to x degrees, therefore, x should be equal to 60 degrees.
