Choose the best description of the relation shown below:
Gre4nikov [31]

There is a rule:

One input(x-value) can only have one output(y-value) in order to be a function.

If one input has more than one output, it is not a function.

(This doesn't apply to outputs, one output can have more than one input and still be a function)

(2,10),(4,15),(6,20),(8,25)

This is a function because each input only has one output.

Your answer is A

Find the value of the variable and YZ if Y is between X and Z. <br><br> XY=4n+3, YZ=2n-7,XZ=22
ruslelena [56]

Answer:

\large \boxed{n = \dfrac{13}{3}; YZ = \dfrac{5}{3}}}

Step-by-step explanation:

I think you have the situation shown in the diagram below.

1. Calculate the value of n

\begin{array}{rcl}XY + YZ & = & XZ\\4n+ 3 + 2n - 7 & = & 22\\6n - 4 & = & 22\\6n & = & 26\\n & = & \dfrac{26}{6}\\\\& = & \mathbf{\dfrac{13}{3}}\\\end{array}\\\large \boxed{\mathbf{n = \dfrac{13}{3}}}

2. Calculate the value of YZ

\begin{array}{rcl}YZ & = & 2n - 7\\& = & 2\left (\dfrac{13}{3}\right ) - 7 \\\\& = & \dfrac{26}{3} - 7\\\\& = & \dfrac{26}{3} - \dfrac{21}{3}\\\\& = & \dfrac{5}{3} \\\\\end{array}\\\large \boxed{YZ = \mathbf{ \dfrac{5}{3}}}

A restaurant sold 35 burgers with cheese if the ratio of the burgers sold with cheese compared to without cheese was 7 : 3 how m
Montano1993 [528]

We need to write a proportion to solve this

7/3=35/x

105=7x

divide each side by 7

15=x so, there were 15 burgers without cheese.

We could add the cheese burgers 35 to burgers without cheese 15

35+15=50 burgers were sold.
