The point of C is, (- 7, - 5).
What is mean by Triangle?A triangle is a three sided polygon, which has three vertices and three angles which has the sum 180 degrees.
Given that;
Triangle ABC with points A (9,1) B (2,7) C(-2,-5) was translated 3 units left, 2 units down and then was reflected across the line y = x.
Now, Triangle ABC with points A (9,1) B (2,7) C(-2,-5) was translated 3 units left, 2 units down.
Hence, The point of C is,
⇒ C = (- 2, -5) + (- 3, - 2)
⇒ C = (- 5, - 7)
Since, It was reflected across the line y = x.
Hence, The point of C is,
⇒ C = (- 7, - 5)

Amit drives a car daily to his office from his home. The distance is 24 km. On a particular day, he left
his home at 8:15 AM, drove for 5 km at a speed of 60 kmph. After that he was stuck in a traffic jam of 1
km during this stretch he could drive only at a speed of 15 kmph.
(Figure shown above is upto scale) Which of these is the closest to the MINIMUM speed at which he
should drive after the traffic jam to ensure that he reaches the office by 8:45 AM?
(Assuming that he can drive the way he wants to, without any traffic jams.
According to the information, it can be inferred that Amit has to drive at a speed of at least 60 km/h to get to work on time.
How to calculate the speed that Amit must have after the traffic jam to get to work on time?To calculate the speed that Amit must have after the traffic jam to arrive at work on time we must perform the following mathematical operation:
speed = 60 * 5 / 18 m/s = 50 / 3 m/s
distance = 5000m
time = 300 seconds = 5 minutes
According to the above he traveled 5 km distance in 5 minutes. On the other hand to calculate the speed that the rest of the journey must have we must:
speed = 15 * 5 /18 = 25/6 m/s
distance = 1000m
time = 240 seconds = 4 minutes
Distance left = (24km -6km = 18km= 18000m
Time left = 21 minutes = 1260 seconds
Speed = 14.28m/s
Speed = 14.28 × 18/5 kmph

Divide the following fractions!
Answer: a - a / (7a/3 - 21b)
Step-by-step explanation:
First, let's simplify the numerator:
(a^2 - 3ab) / 3b = a^2/3b - 3ab/3b = a^2/3b - a
Next, we'll simplify the denominator:
7a - 21b = 7a/3 - 7b
Now, we can simplify the entire expression:
(a^2/3b - a) / (7a/3 - 7b) = (3b * a^2/3b - 3b * a) / (7a - 21b * 3) = a - a / (7a/3 - 21b)
suppose that 17 boys and 22 girls are randomly lined up. what is the probability that the 27th person is a boy?
Using probability we know that there is a 43% chance that the 27th person in the line would be a boy.
What is probability?Probability is simply the possibility that something will happen. When we don't know how something will turn out, we can talk about the possibility of one outcome or the likelihood of several.
The study of events that fit into a probability distribution is known as statistics.
So, we know that:
The boys are 17.
The girls are 22.
Probability formula: P(E) = Favourable events/Total events
Then, the probability that the 27th person is a boy:
P(E) = Favourable events/Total events
P(E) = 17/39
P(E) = 0.43
P(E) = 43%
Therefore, using probability we know that there is a 43% chance that the 27th person in the line would be a boy.

Eight bands are to perform at a weekend festival. How many different ways are there to schedule their appearances?
By using the permutation formula, it can be concluded that there are 40320 ways to schedule the bands' appearances.
Permutations are different arrangements of elements formed from n elements, taken from n or some elements. In permutation, arrangement, or order matter.
P(n,r) = n! / (n-r)! where:
n = number of objects
r = number of objects selected
If we want to know the ways to schedule the bands' appearances, it means that the arrangement matter. Thus we have to use the permutation formula:

Write an equation of the line that passes through (-4,-1) and is perpendicular to the line y=x+6
Answer:
y = -x + 5
Step-by-step explanation:
To find the equation of the line that is perpendicular to the line y = x + 6 and passes through the point (-4, -1), we'll use the slope-point form of the equation of a line. The slope of a line perpendicular to y = x + 6 is -1, which we can find using the negative reciprocal of the slope of y = x + 6. The slope of y = x + 6 is 1. The negative reciprocal of 1 is -1.
So the equation of the line perpendicular to y = x + 6 that passes through the point (-4, -1) is given by:
y - (-1) = -1(x - (-4))
Expanding and simplifying the right-hand side, we get:
y + 1 = -x + 4
y = -x + 5
Write an indirect proof for the following statement:
A triangle can have at most 1 obtuse angle.
We can prove that the statement is false by contradiction, as if a triangle had two obtuse angles, the sum of the measures of the internal angles of the triangle would be greater than 180º.
What is proof by contradiction?To prove an statement by contradiction, we must simply take an statement that either accepts the statement (true) or rejects (false).
An angle is classified as obtuse if it has a measure that is greater than 90º.
The sum of the measures of the internal angles of a triangle is of 180º, hence if the triangle had two obtuse angles, then the sum of the measures of the internal angles of the triangle would be greater than 180º.

you set up a colorful candy bag for your friend with 4 cherry, 8 orange, 2 lemon, 8 grape, and 6 sour raspberry, hard candies. when they pull out two of them, one for each of you, what is the probability they draw 1 cherry and 1 sour raspberry in either order?
Answer:
Step-by-step explanation:
The total number of candies in the bag is 4 cherry + 8 orange + 2 lemon + 8 grape + 6 sour raspberry = 28 candies.
The probability of drawing a cherry on the first draw is 4/28, and the probability of drawing a sour raspberry on the second draw given that a cherry was drawn first is 6/27 (since there are 27 candies left in the bag after the first draw).
The probability of drawing a sour raspberry on the first draw is 6/28, and the probability of drawing a cherry on the second draw given that a sour raspberry was drawn first is 4/27.
Therefore, the probability of drawing one cherry and one sour raspberry in either order is:
(4/28) * (6/27) + (6/28) * (4/27) = 24/756 + 24/756 = 48/756
So the probability of drawing one cherry and one sour raspberry in either order is 48/756.

Answer:
£1 = €1.21875
Step-by-step explanation:
We have the following exchange rates
$1 = £0.64
and
$1 = €0.78
Equating the two values on the right side since they both convert to $1 gives us
£0.64 = €0.78

0.64/0.64 = 0.78/0.64
£1 = €1.21875
