Answer:
A polygon with 18 sides has 18 interior angles. Therefore, to find the measure of one of these angles, divide the sum by 18. Answer: Each angle is 160 degrees.
Step-by-step explanation:
Answer:
y = 2x - 10
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Here m = 2, thus
y = 2x + c ← is the partial equation
To find c substitute (3, - 4) into the partial equation
- 4 = 6 + c ⇒ c = - 4 - 6 = - 10
y = 2x - 10 ← equation of line
Answer:
2(x-3) = y
Step-by-step explanation:
y = 1/2 x +3
To find the inverse, exchange x and y and then solve for y
Exchange x and y
x = 1/2y +3
Then solve for 3
Subtract 3 from each side
x-3 = 1/2 y -3+3
x-3 = 1/2 y
Multiply each side by 2
2 (x-3) = 1/2 *2 y
2(x-3) = y
This is the inverse
