Answer:

AB is 15

Step-by-step explanation:

AB and BC are equal because the line that goes through the triangle is going through at a 90 degree angle, u can see that by the small square, and u know it's in the middle bc of the short lines on AD and DC, the short lines means that they are congruent, so:

5x = 4x + 3

subtract 4x from both sides

x = 3

Now u have x, put it in the equation

5x = 5(3) = 15

The set of points P(0, 3), Q(2, 0), R(4, -3) are collinear and the line has a slope of _____.
Anon25 [30]

If the points P, Q and R are collinear, then a slope of line PQ and a slope of line QR are equal.

The formula of a slope:

m=\dfrac{y_2-y_1}{x_2-x_1}

PQ → (0, 3), (2, 0).

Substitute:

m=\dfrac{0-3}{2-0}=\dfrac{-3}{2}=-1.5

QR → (2, 0), (4, -3).

Substitute:

m=\dfrac{-3-0}{4-2}=\dfrac{-3}{2}=-1.5

CORRECT :)

<h3>Answer: m = -1.5.</h3>
