Answer: it is a function because there aren't for example two 4's that don't have a y value that is a for example 0.
Step-by-step explanation:
Answer:
76
Step-by-step explanation:
decagon = 10 sides
3 heptagons = 3 × 7 = 21 sides
3 nonagons = 3 * 9 = 27 sides
3 hexagons = 3 * 6 = 18 sides
10 + 21 + 27 + 18 = 76 sides in total

Answer:
Step-by-step explanation:
When x is -2, F(x) is undefined.
When x is -1, F(x) is -3.
If we see the third option,
When x is -2, we get the square root of -1, which is undefined.
When x is -1, we get the square root of 0, which is just 0, 0-3 is -3.
Answer:
(-1, -8)
Step-by-step explanation:
So you would do the simplifying by "subtracting" the equations from each other. So to isolate the x, you could subtract the y away.
8x + y = -16
-3x + y = -5
-___________
11x = -11
x = -1
Then, substitute x into either equation.
8(-1) + y = -16
-8 + y = -16
Isolate y.
y = -8
