4. Look at each set of points. If all x-coordinates are different, it is a function. If the same number shows up more than once as an x-coordinate, it is not a function.
Here are the x-coordinates for each choice:
a. 0, 1, 2, 3 All are different. This is a function.
b. 0, 0, 2, 2 There are two zeros and two twos. Not a function.
c. 0, 1, 2, 3 All are different. This is a function.
d. 0, -1, -2, -3 All are different. This is a function.

5. The rate of change is the slope.
a. slope is -3
b. slope = (9 - 7)/(0 - (-1)) = 2
c. 3y + 9x = 10
3y = -9x + 10
y = -3x + 10/3
slope = -3
d. slope = (14 - 10)/(10 - 6) = 4/4 = 1

The greatest slope is 2 in option b.

A T-shirt costs 4 times as much as a pair of socks. a T-shirt costs $16.
alukav5142 [94]
Answer:
D. 4s = 16

Explanation:
We are given that a T-shirt is 4 times the price of the sock.
This means that if we multiply the price of sock by 4, we will get the price of the T-shirt.
In equation form:
price of T-shirt = 4*price of sock

We are given that:
cost of the pair of socks is "s".
cost of T-shirt = 16

Substitute in the above equation, we get:
16 = 4s

Hope this helps :)

Please help me under stand this question.
Oliga [24]

Answer:

It is 3⁸.

Step-by-step explanation:

xᵃ . xᵇ = x⁽ᵃ ⁺ ᵇ⁾

(xᵃ)ᵇ = xᵃᵇ

Using these two conditions we get:

$ 3^{-4} . (3^2)^6 = 3^{-4} . 3^{12} $

$ = 3^{-4 + 12} = 3^8 $

Hence, the answer is 3⁸.
