So we know that an ordered pair looks like (x,y), right? For this inequality, we're supposed to plug in the values of x and y. If it isn't true, then the inequality does not represent the ordered pair.

First option: (0,1)

2x + 3y \geq -1 --> 2(0) + 3(1) \geq -1 --> 5 \geq -1

So this option is correct.

Second option: (-2,1)

2x + 3y \geq -1 --> 2(-2) + 3(1) \geq -1

--> -4 + 3 \geq -1 --> -1 \geq -1

This is also correct.

Third option: (-6,0)

2(-6) + 3(0) \geq -1 --> -12 \geq -1

This is not true, so this option is not correct.

Fourth option: (0,-1)

2(0) + 3(-1) \geq -1 --> -3 \geq -1

This is not correct.

Fifth option: (2,-1)

2(2) + 3(-1) \geq -1 --> 4 - 3 \geq -1

This is correct.

okay so you just plug in the x and ys. x is the first number, y is the second. then you just do them all out

Ms. Pearson kept track of student absences versus final average grades in her math dass for one semester, The
sammy [17]

The correct statement about the data collected by Ms. Pearson is that there is no association between a student's absences and the final average grades.

<h3>When do variables have a linear relationship?</h3>

The equation that represents a linear relationship is: a + bx

Where x represents the rate of increase. Thus, for linear equations, the functiion increases by a constant term.

Looking at the table, the average final grade does not increase by a constant term.

A system of two linear equations with two variables is shown below.
Orlov [11]
{ 3-y=2x
{ x+1/2y=3/2

{ -y=2x-3
{ 1/2y=3/2-x

{ y=-2x+3
{ y=3-2x

-2x+3=3-2x

(x,y) = (x,-2x+3)

HELP!!<br>Find the third term of (x^2+3y)^3
lana66690 [7]

Answer:

T_{3}=27{x}^{2}y^2

Step-by-step explanation:

The given binomial expression is:

( {x}^{2} + 3y)^{3}

When we compare to:

{(a +b)}^{n}

We have

a =  {x}^{2}

b = 3y \\ n = 3

The nth term is given by;

T_{r+1}=^nC_ra^{n-r}b^r

To find the 3rd term, we put:

r + 1 = 3 \\ r = 2

We substitute into the formula to get:

T_{3}=^3C_2( {x}^{2} )^{3-2}(3y)^2

We simply:

T_{3}=3( {x}^{2} )^{1} \times 9y^2

T_{3}=27{x}^{2}y^2
