Part (a)
Since point E is on segment AD, this means the slope of ED is the exact same as the slope of AD.
Use the slope formula to calculate the slope of AD.
m = (y2-y1)/(x2-x1)
m = (7-2)/(4-0)
m = 5/4
<h3>Answer: 5/4</h3>
====================================================
Part (b)
The same idea and steps apply as part (a)
<h3>Answer: 5/4</h3>
====================================================
Part (c)
The x coordinates are the same, so we subtract the y coordinates to find the distance between C and D, which is the length of segment DC.
7-2 = 5
<h3>Answer: 5 units</h3>
====================================================
Part (d)
This time, the y coordinates are the same. We'll subtract the x values
4-2 = 2
<h3>Answer: 2 units</h3>
====================================================
Part (e)
Same idea as part (d), just different numbers this time.
2-0 = 2
<h3>Answer: 2 units</h3>
45 x 73/
100 = 32.85
The answer is 32.85. 32.85 is the price of the item bought after the discount of 45%.
The answer is $10.50 is what he would spend on 2 bags of dog food. Your supposed to divide $15.75 by 3 to find the price of one bag and with the answer you get from that which should be $5.25 you multiply it by 2 so, 5.25x2= 10.50

Step-by-step explanation:
Each point moves to 3 times its original distance from the blue dot. Each length is 3 times as long as the original.
The statement " the measure of angle ABD is 50 degrees, and it is
given that angles ABD and DBC are complementary " justifies why
∠DBC measures 40° ⇒ last answer
Step-by-step explanation:
Let us revise some fact s about angles
1. If two angles are supplementary then the sum of their
measures is 180°
2. If two angles are complementary then the sum of their
measures is 90°
∵ ∠ABD and ∠DBC are complementary ⇒ given
∴ m∠ABD + m∠DBC = 90°
∵ m∠ABD = 50°
∴ 50 + m∠DBC = 90°
- Subtract 50 from both sides
∴ m∠DBC = 40°
The statement " the measure of angle ABD is 50 degrees, and it is
given that angles ABD and DBC are complementary " justifies why
∠DBC measures 40°
