Answer:
Step-by-step explanation:
you have to put the number of sides for n
720 is the sum of interior angles. so to find the value of an angle you have to divide 720 by the number of angles.
we know that,
interior angle + exterior angle = 180 degrees

Answer:
WAT! What diagram???
Step-by-step explanation:
The x-intercept is what 'x' is when 'y' is equal to 0. So plug in 0 for 'y' and solve for 'x':
Simplify:
Divide 4 to both sides:
So the x-intercept is (4, 0).
The y-intercept is what 'y' is when 'x' is equal to 0. So plug in 0 for 'x' and solve for 'y':
Simplify:
Divide 2 to both sides:
So the y-intercept is (0, 8).

Answer:
x = 1, y = 6
or
x = 5, y = 2.
Step-by-step explanation:
y=x2−7x+12
y=−x+7
Substitute for y in the first equation:
- x + 7 = x^2 - 7x + 12
x^2 - 7x + x + 12 - 7 = 0
x^2 - 6x + 5 = 0
(x - 1)(x - 5) = 0
x = 1, 5.
When x = 1, y = -1 + 7 = 6.
when x = 5, y = -5+7 = 2.
