How many ways can Hannah give three of her eight T-shirts to her younger sister?
prisoha [69]
If Hannah gives her younger sister 3 shirts, it does not matter what order she hands them to her. No matter the order, it will still be the same group of 3 shirt. Since order is not important this problem can be solved using a combination.

Specifically we are asked to find 8C3 (sometimes called "8 choose 3"). This is a fraction. In the numerator we start with 8 and count down 3 numbers. In the denominator we start with 3 and count all the way down to 1. Thus we obtain,

\frac{(8)(7)(6)}{(3)(2)(1)}=(8)(7)=56

What is the equation of a line that passes theough the points (-3,4) and (2,8)?​
Salsk061 [2.6K]
<h3><u>Explanation</u></h3>
  • Find the slope by using rise over run with two given coordinate points.

\begin{cases} (x_1,y_1)=(-3,4) \\ (x_2,y_2)=(2,8) \end{cases} \\ m =  \frac{y_2 - y_1}{x_2 - x_1}

  • Substitute the coordinate values in.

m =  \frac{8 - 4}{2 - ( - 3)}  \\ m =  \frac{4}{2 + 3}  \Longrightarrow \frac{4}{5}

We have got the value of slope. Substitute in the slope-intercept form.

  • Slope-Intercept

y = mx + b \\  \sf{m = slope}\\  \sf{b = y - intercept}

Substitute and Rewrite the equation.

y =  \frac{4}{5} x + b

  • Find the y-intercept or the value of b by substituting any given coordinate points.

I will substitute (2,8) in.

y =  \frac{4}{5} x + b \Longrightarrow \sf \small{Substitute \: \: the \:  \: coordinate \:  \: points \:  \: in \:  \: the \:  \: equation}

8 =  \frac{4}{5} (2) + b \\ 8 =  \frac{8}{5} + b \\ 40 = 8 + 5b \\ 40 - 8 = 5b \\ 32 = 5b \\  \frac{32}{5}  = b

Rewrite the equation by substituting the value of b.

y =  \frac{4}{5} x +  \frac{32}{5}

<h3><u>Answer</u></h3>

<u>\large \boxed{y =  \frac{4}{5} x +  \frac{32}{5} }</u>
