Answer:

360

Step-by-step explanation:

The exterior angles always add up to 360 in a polygon because it's the sum of all the vertexes which would make a circle.

Leokris [45]

Answer: y=3

Step-by-step explanation:

first, you need to find the slope using the slope formula (y2-y1/x2-x1)

-4--4/6--7 = 0/13 which equals 0

now you fill it into the point-slope form (y=m(x-x1)+y1)

y=0(x--7)-4

you distribute and get

y=3

Please help me: What's the domain? What's the range? Is it a function?

VladimirAG [237]

Answer:

$\displaystyle Yes \\ Range: Set-Builder\:Notation → [f(x)|-2 ≤ f(x) ≤ 4] \\ Interval\:Notation → [-2, 4] \\ \\ Domain: Set-Builder\:Notation → [x|0 ≤ x ≤ 7] \\ Interval\:Notation → [0, 7]$

Step-by-step explanation:

Just by looking at the graph vertically and horisontally, you can tell what the range and domain is, depending on whether the segments are closed or opened.

* This is a function because it passes the vertical line test.

** This is kind of like a sine wave.

I am joyous to assist you anytime.
