Answer:

Step-by-step explanation:

Mistakes: The student did not distribute the 3 into 2, and the student did not distribute the 6 into negative 2. The student also left out the negative 2x in the first half of the equation.

segment CD has endpoints at C(0, 3) and D(0, 8). If the segment is dilated by a factor of 2 about point C, what is the length of

MatroZZZ [7]

The length of the image of the segment CD is 10 units if the segment CD has endpoints at C(0, 3) and D(0, 8).

<h3>What is a distance formula?</h3>

It is defined as the formula for finding the distance between two points. It has given the shortest path distance between two points.

The distance formula can be given as:

$\rm d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

We have two points C(0, 3) and D(0, 8)

The distance between these two points:

d = √(8-3)²

d = 5 units

The length of the image of segments CD = dilation factor×length of CD

= 2×5

= 10 units

Thus, the length of the image of the segment CD is 10 units if the segment CD has endpoints at C(0, 3) and D(0, 8).

Coordinates (x, y)
Slope Formula: $\displaystyle m = \frac{y_2 - y_1}{x_2 - x_1}$

Step-by-step explanation:

Step 1: Define

Identify points from graph.

Point (20, 0)

Point (100, 40)

Step 2: Find slope m

Simply plug in the 2 coordinates into the slope formula to find slope m

Substitute in points [Slope Formula]: $\displaystyle m = \frac{40 - 0}{100 - 20}$
[Order of Operations] Simplify: $\displaystyle m = \frac{40}{80}$
Simplify: $\displaystyle m = \frac{1}{2}$

hammer [34]

A) 500(.12)= 60 ants per week. Therefore, (10 weeks)(60 ants) = 600ants + 500 ants = 1,100 ants
B) (20 weeks)(60 ants)= 1,200 ants + 500 ants = 1,700 ants
