Answer:

± 3

Step-by-step explanation:

let n be the number then the number squared is n² , so

6n² = 54 ( divide both sides by 6 )

n² = 9 ( take the square root of both sides )

n = ± $\sqrt{9}$ = ± 3

That is the number is 3 or - 3

9) Solve by the elimination method.<br><br> x + y = -5<br> x - y = 11

vlabodo [156]

<h2><u>Answer:</u></h2>

x = 3

y = -8

<h2><u>Step-by-step explanation:</u></h2>

x + y = -5

x - y = 11

Since the y's will cancel out, we don't need to modify the two equations in any way.

Now, just add the two equations.

x + x = 2x

y + (-y) = 0

-5 + 11 = 6

2x = 6

Divide by 2.

x = 3

To find y, plug 3 in as "x" in one of the two equations.

3 + y = -5

y = -8

Write the equation below in slope-intercept form. <br><br> x - y = 2

Arte-miy333 [17]

slope intercept form

y=mx+b

x-y =2

we need to subtract x from each side

x-y-x = -x +2

-y = -x+2

multiply each side by -1

-1*-y = -1(-x+2)

y = x -2

the slope intercept form is

y = x-2

The function will be a (linear function) linear equation in two variable and the equation of the function is y = 87x - 783

<h3>What is a linear equation?</h3>

It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.

If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.

We have given data:

Game(x): 13 14 15 16 17 18

Attendance(y): 348 435 552 609 696 783

If plot these points on a coordinate plane, we will see these points will align in a straight line.

We know we can find a line equation with two points:

(13, 348) and (14, 435)

$\rm (y - 435) = \dfrac{435-348}{14-13}(x-14)$

y - 435 =87(x-14)

y = 87x - 783

Thus, the function will be a (linear function) linear equation in two variable and the equation of the function is y = 87x - 783
