Which table represents a function?

Mathematics
1 answer:
aleksley [76]3 years ago
8 0

Answer:

The first table. (By that, I am referring to the table directly under the question)

Step-by-step explanation:

A function has only one y value for every x value. Thus, for example the coordinates (-5, -5) and (-5, 5) could not be a function.

Likurg_2 [28]

Answer:

  208 1/8 hours

The amount of time saved on each trip is ...

  (3/4 h) - (1/4)(3/4 h) = (3/4)(3/4 h) = 9/16 h

Suppose y varies directly with x. Write a direct variation equation that relates x and y. y=7 1/2 when x=3
kolbaska11 [484]

Answer:

y/x = 2.5

Step-by-step explanation:

y ∝ x

change ∝ to = by adding constant k or c

y = kx

Divide both sides by x

y/x = k, also k = y/x

Input the values

k = (7 1/2)/3.  Change 7 1/2 to improper fraction to give 15/2

k = (15/2)/3

k = \frac{15}{2} ÷ 3  

Change the division sign to multiplication which will change 3 to its inverse(1/3)

k = \frac{15}{2} × \frac{1}{3}

k = \frac{15}{6}

Divide the numerator and denominator by 3 to get 5/2

k = 5/2

From y/x = k,input k into the eqn

y/x = 5/2

y/x = 2.5

I<br> 8. Classify 8 as a perfect square, a perfect cube, both, or neither.
Murljashka [212]

Answer:

It's a perfect cube, but not a perfect square.

Step-by-step explanation:

2^3 = 8, meaning 8 is a perfect cube. But since 2^2 = 4 and 3^2 = 9, and 8 is in between, 8 is not a perfect square.

I hope this helped.
