Answer:

$\bf (\stackrel{x_1}{-13}~,~\stackrel{y_1}{10})\qquad (\stackrel{x_2}{16}~,~\stackrel{y_2}{15}) \n\n\n slope = m\implies \cfrac{\stackrel{rise}{ y_2- y_1}}{\stackrel{run}{ x_2- x_1}}\implies \cfrac{15-10}{16-(-13)}\implies \cfrac{5}{16+13}\implies \cfrac{5}{29}$

$\bf \begin{array}{|c|ll} \cline{1-1} \textit{point-slope form}\n \cline{1-1} \n y-y_1=m(x-x_1) \n\n \cline{1-1} \end{array}\implies y-10=\cfrac{5}{29}[x-(-13)] \n\n\n y-10=\cfrac{5}{29}(x+13)\implies y-10=\cfrac{5}{29}x+\cfrac{65}{29}\implies y=\cfrac{5}{29}x+\cfrac{65}{29}+10 \n\n[-0.35em] \rule{34em}{0.25pt}\n\n ~\hfill y=\cfrac{5}{29}+\cfrac{355}{29}~\hfill$

On a trip, you had to change your money from dollars to British pounds. You got 560 pounds for 800 dollars. How many pounds will you get for 300 dollars?

Answers

Answer

210 pounds

Explanation

First, we are going to find the exchange rate from dollars to pounds.

We know form our problem that 800 dollars are 560 pounds. so:

$(560pounds)/(800dollars) =0.7$ pounds per dollar.

Next, we are going to multiply our exchange rate by the number of dollars we want to change, 300:

$300dollars*(0.7pounds)/(dollar) =210pounds$

We will get 210 pounds for 300 dollars

carter drank 15.75 gallons of water in 4 weeks.he drank the same amount of water each day.about how many days altogether will it take him to drink 20 gallons?

Answers

To answer this first lets see how many gallons of water he drinks per week.

15.75 ÷ 4 = 3.9375

Now lets divide to see how much he drinks each day.

3.9375 ÷ 7 = 0.5625

20 ÷ 0.5625 = 35.5555...

So, it will take Carter about 35 and a half days to finish 20 gallons.
