How do I do this ? & how do I solve it for X&Y

soldier1979 [14.2K]

Simple....

you have:

4x+3y≤-12

To solve for X or Y just isolate the variable....

4x+3y≤-12
-3y -3y

4x≤-3y-12

Now divide by 4....

$\frac{4x}{4} \leq \frac{-3y-12}{4}$

$x \leq -\frac{3y}{4} -3$

Now for y:

4x+3y≤-12

4x+3y≤-12
-4x -4x

3y≤-4x-12

Divide by 3...

$\frac{3y}{3} \leq \frac{-4x-12}{3}$

$y \leq -\frac{4x}{3} -4$

This is the way to solve it.

Thus, your answer.

Answer the following 13,10,7,4,...what is its explicit equation

Studentka2010 [4]

This is an arithmetic sequence.

The numbers differ by a constant.

The general form of an arithmetic sequence is:

$a_n=a+(n-1)d$

Where

a is first term

n is nth term

d is the common difference

Looking at the sequence, we can say the common difference is -3 [since 3 is subtracted from a term to get the next term]

Also, first term is 13

Now, we plug into formula:

$\begin{gathered} a_n=a+(n-1)d \\ a_n=13+(n-1)(-3) \\ a_n=13-3n+3_{} \\ a_n=16-3n \end{gathered}$
