Usimov [2.4K]

Distribute:
-4x+28=36

Subtract 28 from both sides:
-4x=8

Divide both sides by -4;
x=-2

The answer is x=-2

Diane averages 10 mph riding her

aksik [14]

Answer:

20 miles

Step-by-step explanation:

d miles × (1 h)/(10 miles) = d/10 hours

d miles × (1 h)/(40 miles) = d/40 hours

d/40 = d/10 - 3/2

d = 4d - 60

d = 20 miles

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>
