22. Mona is in her garden jumping on stones (as shown below).

iris [78.8K]

$\large\green{\sf\boxed{Given:-}}$

<u>Mona starts from 68th stone</u>

<u>She jumps</u><u> </u><u>23</u><u> </u><u>stones</u><u> </u><u>ahead</u><u> </u>

<u>Then</u><u> </u><u>she</u><u> </u><u>jumps</u><u> </u><u>28</u><u> </u><u>stones</u><u> </u><u>back</u>

$\large\red{\sf\boxed{To \:find:-}}$

<em>Her final position=?</em>

$\large{|\underline{\mathtt{\red{S}\blue{o}\orange{l}\pink{u}\blue{t}\purple{i}\green{o}\red{n}\blue{:}\orange{-}}}}$

Add 23 in 68 [Given]

$\begin{gathered}\\ \sf\longmapsto 68+23=91\end{gathered}$

Subtract 28 from 91

$\begin{gathered}\\ \sf\longmapsto 91-28=Her\:final\:position\end{gathered}$

$\begin{gathered}\\ \sf\longmapsto =63\end{gathered}$

To find how much stones she is ahead or back we will Subtract 63 from 68 which was her initial position.

$\begin{gathered}\\ \sf\longmapsto 68-63=5\end{gathered}$

So, Mona will be <em><u>5</u></em><em><u> </u></em><em><u>stones</u></em><em><u> </u></em><em><u>behind</u></em><em><u> </u></em><em><u>from</u></em><em><u> </u></em><em><u>the</u></em><em><u> </u></em><em><u>starting</u></em><em><u> </u></em><em><u>stone</u></em><em><u>.</u></em>

☯️Hence, Option C is correct

Colin loves to play the piano but doesn't like practicing the exercises his piano teacher assigns. Colin

kati45 [8]

The linear equation for the number of cookies he receives, for x hours practicing the piano, is:

$y = x + 10$

A <u>linear function</u> has the format given by:

$y = mx + b$

In which:

m is the slope, which is the rate of change.
b is the y-intercept, which is the value of y when x = 0.

In this problem:

We have two points: (5,15) and (10,20).
The slope is given by <u>change in y divided by change in x</u>, then:

$m = \frac{20 - 15}{10 - 5} = \frac{5}{5} = 1$

Then

$y = x + b$

Point (5,15) means that when $x = 5, y = 15$ , which is used to find b.

$15 = 5 + b$

$b = 10$

The, the function is:

$y = x + 10$
