<u>Answer:</u>
1/4
<u>Step-by-step explanation:</u>
We are to find the scale factor of the dilation that maps the pre-image of triangle ABC with vertices A(2, 5), B(6, 10) and C(9, −1) to the image triangle A'B'C' with vertices A' (0.5, 1.25), B' (1.5, 2.5), C' (2.25, −0.25).
Center of dilation is at the origin.
To find the scale factor, we will divide the corresponding vertices of the image and pre-image.
A(2, 5) ---> A' (0.5, 1.25) =
B(6, 10) ---> B' (1.5, 2.5) =
C(9, −1) ---> C' (2.25, −0.25) =
Therefore, the scale factor of the dilation is 1/4.
Answer:
First one A and D
Second A and C
Third A and D
Fourth 20 / 4 = X
X = 5
Step-by-step explanation:
Answer:1500
Step-by-step explanation: You divide 750 billion by 500 million
Answer:
B-Tickets
B-15x-500≥1000
C-x≥100
Step-by-step explanation:
X is the variable because you need to find how many tickets need to be sold
The answer is B because they need to raise $1000 or more
15x-500≥1000 (add 500 to both sides)
15x≥1500
x≥100
