Answer:

Step-by-step explanation:

A function cannot have multiple y values for one x value.

Option A lists the y values of -8 and 10 for the x value of -4. Therefore this is not a function.

Option B lists 0, 5, 10, AND 15 all for -1. This can't be a function either.

Option C does not have two of the same x values for different results. Although both 0 and 9 give you the answer of 1 for the y value, this is perfectly okay in a function. This is your answer.

Jayanta is raising money for the? homeless, and discovers each church group requires 2 hr of letter writing and 1 hr of? follow-

boyakko [2]

Answer:

Jayanta needs 2 labor union groups and 8 church groups.

Step-by-step explanation:

Let c denotes churches .

Let l denotes labor unions.

We know that Jayanta can only spend 20 hours letter writing and 14 hour of follow-up.

So, equations becomes:

$2c+2l=20$

$c+3l=14$

And total money raised can be shown by = $150c+175l$

We have to maximize $150c+175l$ keeping in mind that $2c+2l \leq 20$ and $c+3l \leq 14$

We will solve the two equations: $2c+2l=20$ and $c+3l=14$

We get l = 2 and c = 8

And total money raised is $150\times8 + 175\times2$ = $1200+350=1550$ dollars.

Hence, Jayanta needs 2 labor union groups and 8 church groups.
