1/4(24x+12)=6(x+1/2)
forsale [732]

Answer:

The final answer cannot be decided

Step-by-step explanation:

Since 1/4(24x+12)=6(x+1/2)

This can also be written as

24x+12/4=6(x+1/2)

So let's open the bracket from the right side and also solving using the LCM

24x+12/4=6(2x+1/2)

Open the bracket

24x+12/4=3(2x+1)

24x+12/4=6x+3

Cross multiply

24x+12=4(6x+3)

24x+12=24x+12

Collect like terms

24x-24x=12-12

0=0

Therefore the final answer cannot be decided

Does this set of ordered pairs represent a function? Why or why not?
belka [17]

Answer:

A

Step-by-step explanation:

Recall that for a function to be valid, each input value of x must give us one and only one unique output  value for y.

in this case we can see that one of the data sets is (3,-1)

which means that an input of 3 gave an output of -1

but we also see that another data set (3,1)

in this case an input of 3 gave an output of 1.

Because the same x input gives 2 different y outputs, this is not a function.

the answer is A
