. Part A: Under a dilation of scale factor 3 centered at the origin, AB becomes A'B'. Determine the coordinates of A'B' and sketch A'B' on the graph. 1 Part B: Under a dilation of scale factor - centered at the origin, AB becomes DC. Determine the coordinates of DC and sketch DC on the graph.
Answer:
Step-by-step explanation:
Part A.
Coordinates of A and B are,
A(-2, 2) and B(3, 2)
Rule for dilation of a point (x, y) by a scale factor k about the origin,
(x, y) → (kx, ky)
If the points A and B are dilated by a scale factor 3, image points will be,
A(-2, 2) → A'(-6, 6)
B(3, 2) → B'(9, 6)
Part B.
Following the same rule of dilation about the origin by a scale factor of [tex]\frac{1}{2}[/tex] about the origin,
A(-2, 2) → D(-1, 1)
B(3, 2) → [tex]C(\frac{3}{2},1)[/tex]
Write the equation of the green line.
Answer:
y = -1/2x + 2
Step-by-step explanation:
Let the equation of the green line be y = mx + c
From the graph, (-6, 5) and (0, 2) are 2 points on the green line.
m = (2-5)/(0-(-6)) = -1/2 (using gradient/slope formula)
sub (0, 2) and m = -1/2:
2 = -1/2(0) + c
2 = c
therefore,
equation of the line: y = -1/2x + 2

Sarah has saved 254 pound coins. She puts the pound coins into bags.
There are 20 pound coins in each full bag of coins. Sarah is going to take all her full bags of coins to the bank.
She can only take up to 5 full bags of coins to the bank each day.
Sarah wants to go to the bank on as few days as possible.
On how many days will Sarah need to go to the bank?
Answer:
Step-by-step explanation:
So for the fewest days it would be 3 days. The reason for that is because she has 254 pound coins. And she can inly take 5 bags to the bank a day, all of those 5 bags have 100 pound coins in them. If she take 2 days and get 200 pound coins to the bank. Then on the third day she would only have to bring three bags. So your answer for the fewest days possible is three days!

A system of equations has no solution. If y = 8x + 7 is one of the equations, which could be the other equation?
O 2y = 16x +14
O y = 8x - 7
O y = -8x + 7
O 2y = -16x - 14
The other equation could be y = 8x - 7
How to determine the other equation?The first equation is given as:
y = 8x + 7
For the system of equation to have no solution, then the equations in the system would have different constant values.
Take for instance:
y = 8x + b
Where:
b is a constant not equal to 7
From the options, we have:
y = 8x - 7
Notice that -7 and 7 are not the same
Hence, the other equation could be y = 8x - 7

Garret bought 7 bags of apples. The red Apple came in bags of 5 and green came in bags of 2. Garret bought a total of 17 apples. How many of each type of apple did he buy.
Answer:
6 green apple bags and 1 red apple bags
Step-by-step explanation:
6 green apple bags = 12 apples
1 red apple bag= 5 apples
12+5 =17 apples
6+1= 7 bags
Answer:
1 bag of red and 6 bags of green apples.
Step-by-step explanation:
We need to pick 7 bags of apples of different sizes so that the total number of apples = 17.
If Garret bought 1 bag of 5 then the other 12 apples would have to come in 6 bags.
That is 6 bags of 2 apples.

question: Your mass on earth is 50 kilograms. What is your mass on the moon?
Answer:
No matter if you are on Earth, the moon or just chilling in space, your mass does not change. But your weight depends on the gravity force; you would weigh less on the moon than on Earth, and in space you would weigh almost nothing at all. Where ever you are, your mass will always stay the same.
Answer:
50 kilograms
Step-by-step explanation:
Mass never changes, and is constant everywhere. The weight is what changes. If you weigh 50 kg on Earth, you'll weigh 50 kg everywhere else in the universe. That's because the amount of matter in you cannot change.
