Answer:

x-int: (2, 0)

y-int: (0,8)

(8-0)/(0-2)= 8/-2= -4

y - 0 = -4(x - 2)

y = -4x + 8

The Pine Apple Store found that 18% of their weekly customers would purchase a new R-phone before leaving the store. If this was

Ahat [919]

Answer:

350 customers

Step-by-step explanation:

Since this is a ratio question and we only have variable that we need to solve (total people that entered last week), Then we can use the Rule of Three to solve this problem. We do this by multiplying the diagonal values of the following model and dividing by the third value in order to find the variable, like so...

18% of customers <====> 63 customers

100% of customers <====> x customers

(100 * 63) / 18 = x

6,300 / 18 = x

350 = x

Finally, we can see that a total of 350 customers entered the store last week.

Find an expression for the function whose graph is the line segment joining the points (1, -1) and (5, 5). (Assume that these po

bagirrra123 [75]

Namely, what's the equation of a line that passes through (1,-1) and (5,5)

well, first off let's find its slope, and the plug all those values in the point-slope form.

$\bf \begin{array}{lllll}
&x_1&y_1&x_2&y_2\\
% (a,b)
&({{ 1}}\quad ,&{{ -1}})\quad 
% (c,d)
&({{ 5}}\quad ,&{{ 5}})
\end{array}
\\\\\\
% slope = m
slope = {{ m}}= \cfrac{rise}{run} \implies 
\cfrac{{{ y_2}}-{{ y_1}}}{{{ x_2}}-{{ x_1}}}\implies \cfrac{5-(-1)}{5-1}\implies \cfrac{5+1}{5-1}
\\\\\\
\cfrac{6}{4}\implies \cfrac{3}{2}$

$\bf \stackrel{\textit{point-slope form}}{y-{{ y_1}}={{ m}}(x-{{ x_1}})}\implies y-(-1)=\cfrac{3}{2}(x-1)
\\\\\\
y+1=\cfrac{3}{2}x-\cfrac{3}{2}\implies y=\cfrac{3}{2}x-\cfrac{3}{2}-1\implies y=\cfrac{3}{2}x-\cfrac{5}{2}$
