Answer: A) Reflection along the line y = -1
===========================================================
Explanation:
Point A is at (1,5). Point A' is at (1,-7).
Apply the midpoint formula to find the center of these two points.
You should get (1,-1) as that midpoint.
Follow these steps for B(-1,3) and B'(-1,-5) to get the midpoint (-1,-1)
Those midpoints we found are located on the mirror line. We only need two such points to plot it. Drawing a line through (1,-1) and (-1,-1) graphs the equation y = -1. This is the horizontal line through -1 on the y axis.
Step-by-step explanation:
<h2>What is the rate of change of the line through (3, -5) and (-5, 3)?..........</h2>
Answer:
3 7/18
Step-by-step explanation:
2 1/6 + 1 2/9 (- cancels with the - to give us +)
Convert to simple fraction: 13/6 +11/9
Find the common denominator: 13x 3/6x3 + 11 x 2/9 x 2
39/18 + 22/18
Now that the denominators are same, conduct the given operation.
39 + 22/ 18
61/18
Convert into mixed fraction: 3 7/18
Final answer: 3 7/18

Answer:
9/23
Step-by-step explanation:
Of the 23 students, 9 play both baseball and basketball. The probability of choosing one of those is 9/23.
___
Let A represent basketball, and B represent baseball. Then ...
P(A or B) = P(A) +P(B) -P(A and B)
Since 8 students play neither sport, we have ...
1 -8/23 = 11/23 +13/23 -P(A and B)
15/23 = 24/23 -P(A and B)
P(A and B) = (24 -15)/23
P(A and B) = 9/23
