How do you solve for y in the equation:

="\frac{x}{y} =y-6" alt="\frac{x}{y} =y-6" align="absmiddle" class="latex-formula"> and is it a function?

No it isn't.

Explanation:

x/y * y = (y-6) * y

x = y^2 - 6y

A function gives just one y for every x

In this case there will always be 2 y's for every x

Example:

y can be

y = 6

or

y =−6

(0,-6) & (0,6)

What is the slope of 7x+3y<-26

pogonyaev

Answer:

-7/3.

Step-by-step explanation:

Convert to the form y < mx + c where m is the slope:

7x + 3y < -26 Subtract 7x from both sides:

3y < -7x - 26 Divide through by 3:

y < (-7/3)x - 26/3

So the slope is -7/3.

(05.05) On a coordinate plane the coordinates of vertices R and T for a polygon are R(-7, 3) and T(3,3). What is the length of S

Talja [164]

Answer:

c) 10 units

The length of side RT of the polygon RT = 10

Step-by-step explanation:

<u><em>Step(i):-</em></u>

Given the coordinates of vertices R and T

R( -7 ,3) and T (3 ,3)

we have to find the length of side RT

We will use distance formula

RT = $\sqrt{(x_{2} -x_{1})^{2} +(y_{2} -y_{1} )^{2} }$

<u><em>Step(ii):-</em></u>

RT $= \sqrt{(3-3)^{2} +(3-(-7))^{2} }$

$RT = \sqrt{0+(10)^{2} }$

RT = √100

RT = 10

The length of side RT of the polygon RT = 10

Marc decided to buy a set of 6 leather chairs for his dining room. He has decided to spend no more than $360. He receives coupon

Nookie1986 [14]

6(c-20)≤360 divide both sides by 6

c-20≤60 add 20 to both sides...

c≤80

So the original cost of chairs must be $80.00 or less.
