The initial value equals the y-intercept. The equation is in the slope-intercept formula where b is the y-intercept. The answer would be -7. [Note: If it's + in front of the b value, it's a positive value (b). If - is in front of it, it's a negative value (-b).]
Answer: 2,3,8
Step-by-step explanation:
if,
x+y+z=13
2x+5y+6z=67
5x-y=7
Solve [x+y+z=13 2x+5y+6z=67] to find: -3x+z=2 and keep
|
x+y+z=13
5x-y=7
6x+z=20 and -3x+z=2
z=8
x=2
y=3
Answer:
6
Step-by-step explanation:
Given information:
Interior angle of a polygon cannot be more that 180°.
One interior angle = 
Other interior angles are = 
Let n be the number of sides of the polygon.
Sum of interior angles is


Combine like terms.
.... (1)
If a polygon have n sides then the sum of interior angles is

.... (2)
Equating (1) and (2) we get
Isolate variable terms.
Divide both sides by 52.
Therefore the number of sides of the polygon is 6.
