Ed and Adam take long walks every evening. Ed walks at a constant speed of 2 miles per hour, and Adam walks at a constant speed

Softa [21]

<u>Answer:</u>

Both will be at equal distance at 8 miles in 2 hours.

<u>Step-by-step explanation:</u>

<u>We know that:</u>

Ed = 2 miles/hour
Adam = 4 miles/hour

<u>Work:</u>

Ed => 4 miles

Adam => 0 miles

Ed => 6 miles => 1 hour

Adam => 4 miles => 1 hour

Ed => 8 miles => 2 hour

Adam => 8 miles => 2 hour

Hence, <u>both will be at equal distance at 8 miles in 2 hours.</u>

Hoped this helped.

Line AB and CD have the following points: A(2, 4), B(9, 8), C(-1, 2), and D(3, -5). Are the lines parallel, perpendicular, or ne

inysia [295]

We are given coordinates of A, B, C and D :

A(2, 4), B(9, 8), C(-1, 2), and D(3, -5).

Now, we need to find the slopes of AB and CD.

Slope of AB is :

$\mathrm{Slope\:between\:two\:points}:\quad \mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}$

$\left(x_1,\:y_1\right)=\left(2,\:4\right),\:\left(x_2,\:y_2\right)=\left(9,\:8\right)$

$m=\frac{8-4}{9-2}$

$m=\frac{4}{7}$ .

Slope of CD is:

$m=\frac{-5-2}{3-\left(-1\right)}$

$m=-\frac{7}{4}$ .

<em>Slope of CD is negative reciprocal of slope of slope of AB. </em>

<h3>Therefore, lines AB are CD are perpendicular.</h3>
