Answer:
No, because the x value of 1 correlates to two different y values.
Step-by-step explanation:
A function is defined by an x value having exactly one corresponding y value. In this case, the x value of 1 corresponds to both the y values of 2 and 8, therefore invalidating it as a function.
Hope this helps!
The perimeter is D because you have to add all the sides up. 2 + 2 and 3 plus 3 equals 10x and then 8 + 8 and 2 + 2 equals 20 so 10x- 20.
Answer:

Step-by-step explanation:
x = y - 7 ---------------------(1)
-y - 2x = 8 --------------------(2)
Put Equation (1) into (2)
- y - 2 ( y-7 ) = 8
-y - 2y + 14 = 8
-3y = 8 - 14
-3y = -6
Divide -3 to both sides
y = -6 / -3
y = 2
Put y = 2 in (1)
x = 2 - 7
x = -5
So,
x = -5 , y = 2

Answer:
aₙ = -2aₙ₊₁
Step-by-step explanation:
According to the sequence given 16, -8, 4, ...
a1 = 16
a2 = -8
a3 = 4
From the values, we can conclude thst;
a1 = -2(-8)
Since a2 = -8, then;
a1 = -2(a2)
Similarly
a2 = -2(4)
a2 = -2a3
The subsequent sequence are;
a3 = -2a4
The nth term will ne;
aₙ = -2aₙ₊₁
Hence the required recursive function is aₙ = -2aₙ₊₁
