$100\%-20\%=80\%\\\\\begin{array}{ccc}80\%&-&\£1200\\\\100\%&-&\£x\end{array}\\\\\\cross\ multiply\\\\80x=1200\times100\\\\80x=120,000\ \ \ \ |divide\ both\ sides\ by\ 80\\\\x=1500\ (\£)\\\\Answer:The\ computer's\ original\ price\ was\ \£1500.$

Find an equation perpendicular to x=1 and passing through (8,-9)

valina [46]

Answer:

$y=-9$

Step-by-step explanation:

We want to find an equation of a line that's perpendicular to x=1 that also passes through the point (8,-9).

Note that x=1 is a vertical line since x is 1 no matter what y is.

This means that if our new line is perpendicular to the old, then it must be a horizontal line.

So, since we have a horizontal line, then our equation must be our y-value of our point.

Our y-coordinate of our point (8,-9) is -9.

Therefore, our equation is:

$y=-9$

And this is in standard form.

And we're done!

JK is formed by J(-12,3) and K(8,-5). If line r is the perpendicular bisector of JK, write an equation for r in slope-intercept

dem82 [27]

Answer:

y = 5/2x + 4

Step-by-step explanation:

Midpoint of JK:

x = (-12 + 8)/2 = -4/2 = -2
y = (3 - 5)/2 = -2/2 = -1

Slope of the line JK:

m = (-5 - 3)/(8 - (-12)) = -8/20 = -2/5

Perpendicular lines have negative reciprocal slopes.

So the line r has a slope 5/2 and passes through the point (-2, -1)

Equation of r:

y = 5/2x + b
-1 = 5/2(-2) + b
-1 = -5 + b
b = 5 - 1
b = 4

So the equation is:

y = 5/2x + 4
