Answer:
<h3>
R(-1, -9)</h3>
Step-by-step explanation:
When we reflect over x-axis then the x-coordinate doesn't change and the y-coordinate changes its sign
in means if R = (x, y) then R' = (x, -y)
so we have:
x = -1 and -y = 9
y = -9
which gives R = (-1, -9)
Before Brian starts messing with them, there are 24 balls in the bag.
9 of them are white.
-- The probability that Brian draws a white ball from the bag is (9/24) .
If he has already drawn one white ball and put it aside, then there are
23 balls left in the bag, and 8 of them are white.
-- The probability that Brian draws a white ball from the bag this time
is (8/23) .
So the probability of white balls on both draws is
(9/24) x (8/23) =
(72/552) =
3 / 23 = about <em>13% </em>(rounded)
Base in your question the coordinate is P is 2, PQ has a coordinate of 8 while PR has a coordinate of 12. To find the mid point of each segment you must first find the coordinate of QR which is from 8-12. So the answer will be
PQ = 5, PR = 6, and QR= 10
Answer:
Step-by-step explanation: The order of operations is a rule that tells the correct sequence of steps for evaluating a math expression. We can remember the order using PEMDAS: Parentheses, Exponents, Multiplication and Division (from left to right), Addition and Subtraction (from left to right).
