Step-by-step explanation:
Answer:
180 degrees
Step-by-step explanation:
3/12 as a decimal is 0.25
Step-by-step explanation:
Looks like you want all equations converted into slope-intercept form.
- 2x + y = 2 ⇒ y = -2x + 2
- x + 2y = 4 ⇒ 2y = - x + 4 ⇒ y = - 1/2x + 2
- 2x - y = 2 ⇒ y = 2x - 2
- x - 2y = 4 ⇒ 2y = x - 4 ⇒ y = 1/2x - 2
