so we have a table of values, with x,y coordinates, so let's use any two of those points to get the slope of the table and use the point-slope form to get its equation

~\hspace{2.7em}\stackrel{\textit{let's use}}{\downarrow }\qquad \stackrel{\textit{and this}}{\downarrow }\\\begin{array}{|lr|r|r|r|r|}\cline{1-6}x&0&1&2&3&4\\y&-1&3&7&11&15\\\cline{1-6}\end{array}\\\\[-0.35em]\rule{34em}{0.25pt}\\\\(\stackrel{x_1}{1}~,~\stackrel{y_1}{3})\qquad(\stackrel{x_2}{4}~,~\stackrel{y_2}{15})

\stackrel{slope}{m}\implies\cfrac{\stackrel{rise}{\stackrel{y_2}{15}-\stackrel{y1}{3}}}{\underset{run}{\underset{x_2}{4}-\underset{x_1}{1}}}\implies \cfrac{12}{3}\implies 4\\\\\\% point-slope intercept\begin{array}{|c|ll}\cline{1-1}\textit{point-slope form}\\\cline{1-1}\\y-y_1=m(x-x_1)\\\\\cline{1-1}\end{array}\implies y-\stackrel{y_1}{3}=\stackrel{m}{4}(x-\stackrel{x_1}{1})\\\\\\y-3=4x-4\implies y = 4x-1\implies \blacktriangleright  y = 4x+(-1)\blacktriangleleft

Kimane and a friend picked apples. Kimane picked 4 2/3 and his friend picked 5 5/6 pounds. About how many pound of apples do the
Gala2k [10]

Answer:

9\dfrac{1}{2}

Step-by-step explanation:

To find many more pounds of apples Kimane and his friend needs to get, we first need to find out how many pounds of apples they picked together.

Kimane = 4\dfrac{2}{3}

Friend = 5\dfrac{5}{6}

We add them together to find out how many pounds of apples they currently have.

Total Pounds = 4\dfrac{2}{3}+5\dfrac{5}{6}

Just to make the equation clearer, we separate the whole numbers from the fractions.

=4+5+\dfrac{2}{3}+\dfrac{5}{6}

=9+\dfrac{2}{3}+\dfrac{5}{6}

Now since we cannot add the 2 fractions directly since they have different denominators, we need to convert the /dfrac{2}{3} into a fraction with the same denominator.

We multiply both the numerator and denominator by 2 to have the same denominator.

\dfrac{2*2}{3*2}=\dfrac{4}{6}

So now we have:

=9+\dfrac{4}{6}+\dfrac{5}{6}

=9+\dfrac{9}{6}or1\dfrac{1}{2}

Total Pounds = 10\dfrac{1}{2}

Now that we know how many pounds Kimane and his friend collected, we simply subtract 20 and the total amount Kimane and his friend had already collected.

20-10\dfrac{1}{2}

=9\dfrac{1}{2}

So Kimane and his friend still need to get 9\dfrac{1}{2} more pounds of apples to get 20 pounds of apples.

David's total income is ($8/hr)x + ($11/hr)y.

This problem requires us to write and solve an inequality:

8x + 11(15)<$200

Solving for x:     8x < $200-$165, or 8x < $35.  Strictly speaking, x = 4.375 hrs, but if we assume that David must work an integer # of hours, then x=5 full hours.
