Aleks [24]

Answer:

$y =1 -x$

Step-by-step explanation:

Given

$A = (4,2)$

$B = (4,5)$

$C = (1,2)$

$D = (2,-4)$

$E = (5,-4)$

$F = (2,-1)$

Required

Determine the equation of line EF perpendicular to BC at intersect 0,1

The question has missing attachment but it can still be solved;

First, we need to determine the slope of BC using

$m = \frac{y_2 - y_1}{x_2 - x_1}$

Where

$(x_1,y_1) = (4,5)$ Point B

$(x_2,y_2) = (1,2)$ Point C

Substitute these values in the above formula

$m_1 = \frac{2 - 5}{1 - 4}$

$m_1 = \frac{- 3}{- 3}$

$m_1 = 1$

Next is to determine the slope of EF;

Since, there are perpendicular: we have

$m_1 * m_2 = -1$

Substitute -1 for m1

$1 * m_2 = -1$

$m_2 = -1$

Next, is to determine the slope of EF at intersect (0,1).

The formula to use is:

$y - y_1 = m_2(x - x_1)$

In this case;

$(x_1,y_1) = (0,1)$

Substitute values for m2, x1 and y1

$y - 1 = -1(x - 0)$

$y - 1 = -1(x)$

Open the bracket

$y - 1 = -x$

Add 1 to both sides

$y - 1 +1 =1 -x$

$y =1 -x$

Hence;

The equation is $y =1 -x$

The distance between the cities is 280 miles. The rule is y = 40x, where x is the distance in inches on the map and y is the distance in miles.

Step-by-step explanation:

Step 1:

The map's key shows that 5 inches on the map equal 200 miles of actual distance.

5 inches on the map = 200 miles of actual distance,

if we divide both sides by 5, we get;

1 inch on the map = 40 miles of actual distance.

Step 2:

If x is the distance on the map in inches and y is the actual distance in miles,

y = 40x.

If the map distance 7 inches, x = 7.

Substituting, x =7 in the equation, $y = 40(7) = 280$ .

So the actual distance between the cities is 280 miles.
