What is the equation of the perpendicular to y=2/3x+1 that passes through the point (12,-6)

postnew [5]

Well, first off let's check what is the slope of y = 2/3x+1.... .hmmmmm, notice $\bf y=\stackrel{slope}{\cfrac{2}{3}}x+1$ , since the equation is already in slope-intercept form, we can see it has a slope of 2/3.

well then, a line perpendicular to that one, will have a negative reciprocal to it.

$\bf \textit{perpendicular, negative-reciprocal slope for slope}\quad \cfrac{2}{3}\\\\
slope=\cfrac{2}{{{ 3}}}\qquad negative\implies -\cfrac{2}{{{ 3}}}\qquad reciprocal\implies - \cfrac{{{ 3}}}{2}$

so, we're really looking for the equation of a line whose slope is -3/2 and goes through 12, -6.

$\bf \begin{array}{lllll}
&x_1&y_1\\
% (a,b)
&({{ 12}}\quad ,&{{ -6}})
\end{array}
\\\\\\
% slope = m
slope = {{ m}}= \cfrac{rise}{run} \implies -\cfrac{3}{2}
\\\\\\
% point-slope intercept
\stackrel{\textit{point-slope form}}{y-{{ y_1}}={{ m}}(x-{{ x_1}})}\implies y-(-6)=-\cfrac{3}{2}(x-12)
\\\\\\
y+6=-\cfrac{3}{2}x+18\implies y=-\cfrac{3}{2}x+12$

Callie is comparing the costs of two options for her college education.

Ainat [17]

Answer:

Callie's comparison of two options for college education

The true statement is:

She would save $11,300 by choosing option A.

Step-by-step explanation:

Cost Analyses:

Option A: Community College + University Total Expenses

Tuition & Fees $5,800 ($2,900 x 2) + $19,000 ($9,500 x 2) = $24,800

Scholarships ($1,600) ($800 x 2) + ($20,000) ($10,000 x 2)=($21,600)

Room & Board $2,500 ($1,250 x 2) + $23,000 ($11,500 x 2) = $25,500

Work-Study + ($4,000) ($2,000 x 2) = ($4,000)

Total Cost $6,700 + $18,000 = $24,700

Option B: 4 years' University

Tuition & Fees $38,000 ($9,500 x 4)

Scholarships ($40,000) ($10,000 x 4)

Room & Board $46,000 ($11,500 x 4)

Work-Study ($8,000) ($2,000 x 4)

Total Cost $36,000

Difference between the two options = $11,300 ($36,000 - $24,700
