Please help me with these two questions.
Answers
The first one, you take (x,y) both times 3
A(1,1) to A(3,3)
B(-1,1) to B(-3,3)
C(1,-1) to C(3,-3)
D(-1,-1) to D(-3,-3)
The second one, you take (x,y) both times 2
A(4,1) to A(8,2)
B(4,3) to B(8,6)
C(1,2) to C(2,4)
That is how I think you do it. I hope that I helped you.
Find the length of the side of the smaller square. So subtract the x-values from each other.
1-(-1)=2
The length of the square is 2.
Now find the length of the bigger square.
3-(-3)=6 (You can also just count the units between the two points.)
Now divide the length of the bigger triangle by the length of the smaller triangle to find the scale factor used to dilate the object.
The scale factor is 3.
18)
Find the base of the larger triangle.
The y-value for point B is 6 and the y-value for point A is 2. Just subtract to find the length of BA.
6-2=4
Now find the base of the smaller triangle.
The y-value for point B is 3 and the y-value for point A is 1. Just subtract to find the length of B'A'.
3-1=2
Divide the base of the smaller triangle by that of the larger triangle.
The scale factor is 1/2.

Now you might be wondering why I divided the smaller triangle by the larger one but I didn't follow the same procedure for the squares. If you look closely, the smaller triangle is the new figure after the scale factor dilation while the larger square is the new figure after the scale factor dilation. Just look at the coordinates. The coordinates for a changed figure always has an apostrophe at the end of it. The bigger square in question 17 has the apostrophes so I knew that the larger square was the new figure after the dilation. And the smaller triangle in question 18 has the apostrophes so I knew that the smaller triangle was the new figure after the dilation.

Left chain = 3 5/12 - 2 1/3
L.C. = 41/12 - 7/3
L.C.= 41-28 / 12
L.C. = 13/12
In short, Your Answer would be 13/12 feet or 1 1/12 feet

Final answer:
The Yankees won approximately 55.56% of their games last season. We calculated this by dividing the number of games they won (90) by the total number of games played (162) and then multiplying the result by 100.
Explanation:
To calculate the percentage of games won by the Yankees, we divide the number of games they won by the total number of games played, and then multiply the result by 100. This can be represented mathematically by the formula: (Number of wins / Total number of games)*100.
So in this case, they won 90 games out of a total of 162. Plugging those figures into our formula gives us: (90/162)*100 which is approximately 55.56%. Therefore, the Yankees won approximately 55.56% of their games last season.

Answer:
Step-by-step explanation:
f(x) = ax+b
passing through the point (6,-1) : when x = 6 f(x) = -1
means : -1 = a (6)+b
passing through the point (-3,-2) : when x = -3 f(x) = -2
means : --2 = a (-3)+b
you have the system :: 6a +b = - 1......(1)
-3a +b = -2........(2)
by (1) : b = -1 - 6a
by (2) : b = -2+3a
so : -2+3a = -1 - 6a
3a+6a =2 -1
9a =1 a =1/9 put the value of a in (1) or (2) : -3(1/9)+b = - 2
-1/3 +b = - 2
b = -2+1/3
b = -5/3
f(x) = 1/9 x - 5/3

Answer: 55/17
Step-by-step explanation: To write a mixed number as an improper fraction, first multiply the denominator by the whole number, then add the numerator.
So here we multiply the denominator (17) by the whole number (3), then we add the numerator which is 4.
Finally, we put our new number over our old denominator and we have our answer 55/17.
Therefore, 3 and 4/17 can be rewritten as the improper fraction 55/17.

Step-by-step explanation: The commutative property of multiplication states that changing the order of the factors does not change the product.
Example:
4 × 10 ≈ 10 × 4
If we multiply both these numbers together, we will get the same answer which is 40. This means that 4 × 10 must be equal to 10 × 4.
Example:
3 × 2 ≈ 2 × 3
Both of the answers will equal 6 which means that they are equal to each other.
Example: 4x3x9=108
Just like: 4x9x3=108
Or: 9x3x4=108
Another example: 10x5x2=100
Just like: 5x2x10=100
Or: 2x10x5=100
