Answer:
x = 7
Step-by-step explanation:
The sum of interior angles is equal to 360°
9x - 4 + 8x + 2 + 13x + 30 + 19x - 11 = 360° add like terms
49x + 17 = 360 subtract 17 from both sides
49x = 343 divide both sides by 49
x = 7
replace x with the value we found to calculate each angle.
Answer:
the first option is correct
since value of a will be found through division.
Answer:
(0, -7)
Step-by-step explanation:
The y-intercept is the point on the line where x = 0 (AKA where the line crosses the y-axis).
Here, the y-intercept is literally given within the question as (0, -7).
