You need to combine like terms. So it would be 14x.

Mike had 280 dollars to spend on 8 books.After buying them he had 16 dollars. How much did each book cost?

adell [148]

Well, you can't really determine the price of 1 book, but you can find out the average cost.

280 - 16 = 8x (x = cost of 1 book)
264 = 8x
264/8 = 8x/8
33 = x

So the average cost of one book is 33$( A little expensive if I do say so myself)
Hope this helped!

Find the slope of the line that contains the points named a (o,d),b (d,o)

V125BC [204]

$\bf \begin{array}{lllll}
&x_1&y_1&x_2&y_2\\
% (a,b)
&({{ 0}}\quad ,&{{ d}})\quad 
% (c,d)
&({{ d}}\quad ,&{{ 0}})
\end{array}
\\\\\\
% slope = m
slope = {{ m}}= \cfrac{rise}{run} \implies 
\cfrac{{{ y_2}}-{{ y_1}}}{{{ x_2}}-{{ x_1}}}\implies \cfrac{0-d}{d-0}\implies \cfrac{-d}{d}\implies -1$
