A line passes through the points 3,10 and 6, 16 write the equation of this line in slope-intercept form
cluponka [151]

(\stackrel{x_1}{3}~,~\stackrel{y_1}{10})\qquad (\stackrel{x_2}{6}~,~\stackrel{y_2}{16}) ~\hfill \stackrel{slope}{m}\implies \cfrac{\stackrel{rise} {\stackrel{y_2}{16}-\stackrel{y1}{10}}}{\underset{run} {\underset{x_2}{6}-\underset{x_1}{3}}} \implies \cfrac{ 6 }{ 3 } \implies 2

\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}{10}=\stackrel{m}{ 2}(x-\stackrel{x_1}{3}) \\\\\\ y-10=2x-6\implies {\Large \begin{array}{llll} y=2x+4 \end{array}}

Seventy-five percent of the apple pies were sold on Tuesday, and the remainder were thrown out. If 12 apple ples were sold Tuesd
LUCKY_DIMON [66]

Answer:

4 pies

Step-by-step explanation:

Hello!

We know that 12 apple pies are 75 percent of the total apple pies.

Let x = # of pies total.

This means that 75% of x, or 0.75x is 12

Solve:

  • 75% of x = 12
  • 0.75x = 12
  • x = 16

Now, 16 is the total number of pies. To find the number thrown out, we subtract 12.

16 - 12 = 4

4 pies were thrown out
