Answer:
variable
Step-by-step explanation:
the variable
(6× + 3) means (6×1 + 3)
x is a variable
Answer:
73°
Step-by-step explanation:
3x + x - 17 + 2x - 61 = 360°
6x - 78 = 360°
6x = 438°
x = 73°
It rises to the right so the slope is negative
Slope = rise / run = 18 / -9 = -2
The y intercept is at y = -3 so using the form y = mx + b we get
y = -2x - 3 which is option B (answer)
