Answer:

\frac{4}{9} y - 7 =  - 3

• Add 7 to all sides:

( \frac{4}{9} y - 7) + 7 =  - 3 + 7 \\  \\  \frac{4}{9} y = 4

• multiply either sides by 9:

( \frac{4}{9} y) \times 9 = 4 \times 9 \\  \\ 4y = 36

• divide either sides by 4:

\frac{4y}{4}  =  \frac{36}{4}  \\  \\ { \underline{ \underline{ \:  \: y = 9 \:  \: }}}

Graph the solution set of this inequality: 5x − 4y > 20.
Yanka [14]

Answer:

Step-by-step explanation:

Solve the inequality 5x − 4y > 20 for y, as follows:  Subtract 5x from both sides, obtaining:

-4y > 20 - 5x;

Then divide all terms by -4:

y    < -5 +(5/4)x, where the direction of the inequality sign has been reversed because of division by a negative quantity.

Temporarily replace the < symbol with =     obtaining    y = -5 +(5/4)x.  Now choose at least three x values and find the corresponding y values.  For example:

 x      y = -5 +(5/4)x  

 0          -5

 4            0

 -8         -15

Now plot these three points (0, -5), (4, 0) and (-8, -15).  Draw a dashed line through them.  Because of the < symbol in y    < -5 +(5/4)x, shade the area underneath the dashed line.

The parabola y=x^2 is reflected across the x axis and then scaled vertically by a factor of 1/8.
tekilochka [14]

ANSWER

The new equation is:

y =  -  \frac{1}{8}  {x}^{2}

EXPLANATION

The given parabola has equation,

y =  {x}^{2}

This is the parent function.

When we reflect this parabola in the x-axis and then scaled vertically by a factor of 1/8.

The new equation becomes:

y =  -  \frac{1}{8}  {x}^{2}

Explain when the median of a data set is a better measure of center than the mean.
shusha [124]
With data, you can have outliers. Outliers are values that do not follow what the range or majority of the data you collected so a value of 45, 42, 45, 48, 42, 44, 88, the mean will obviously be different because the 88 is going to change the whole data. But, if you put it from least to greatest, you can see what the majority of data is, (what the middle value is) to see what is in the middle range of what you have collect- the outliers don't affect what you have. Hence, 42, 42, 44, 45, 45, 88 (it's not much data) but it can show what the majority of data is. Hope this helps :> :)
