Answer:
Step-by-step explanation:
point slope form
y + 6 = -3(x - 4)
point slope to y-intercept
y + 6 = -3x + 12
y = -3x + 6
Just add them all up and divide by how many numbers there are
6+12+22+16=56
56 divided by 4 = 14
14 is the mean
Answer:
x=69° y=69°
Step-by-step explanation:
Angle x is an alternate angle so it is equal to the angle above it (69)
Angle y is in a co-interior angle so you do the equation 180-111 which equals 69°
N is greater than or equal to 5
So that is the first one.
Hope that help you.
