Answer:
(5,-2)
Step-by-step explanation:
Here, we want to find the coordinates of point after reflection on both x and y axes
After reflection given that the line is y = x
The new points become (y,x)
And as such in this case, we have (5,-2)
sum n=3 ^ infty (2n+5)
find the series shown
=====================================================
Explanation:
We're adding terms in the form (2n+5)
The first term is when n = 3, so
2n+5 = 2*3+5 = 6+5 = 11
The next term is when n = 4, so
2n+5 = 2*4+5 = 8+5 = 13
The next term is when n = 5, so
2n+5 = 2*5+5 = 10+5 = 15
And so on
This means,
[tex]\displaystyle \sum_{n=3}^{\infty} (2n+5) = 11+13+15+17+\ldots[/tex]
which matches with choice C. The three dots indicates the pattern goes on forever.
-------------------
Choice B does not have these dots, so that's why choice B is not the answer. If we replaced the infinity symbol with 7, then choice B would be the answer.
I.e,
[tex]\displaystyle \sum_{n=3}^{7} (2n+5) = 11+13+15+17+19[/tex]

Alisa bought 3 shirts for $29 each and then spent $15 on lunch. She has $31 left. How much money did she have before?
Answer:
$133
Step-by-step explanation:
Let x = amount of money she had before she spent any money.
x - 29 - 29 - 29 - 15 = 31
x - 102 = 31
x = 133
Answer: She had $133.
Answer:
she had 133$
Step-by-step explanation:
Multiply 29$ by the amount of shirts and get 87$
then add 31$, the 15$ she spent on lunch, and add the 87$ and get 133$.

Use the distance formula to find the distance, to the nearest tenth, from S(5, −4) to W(−3, 7).
Answer:
185
Step-by-step explanation:
distance formula is d=√((x_2-x_1)²+(y_2-y_1)²
so it would be d=[tex]\sqrt{(-3-5)^{2} + (7-(-4))^{2} }[/tex]
where we see [tex](7-(-4))^{2}[/tex] will turn into [tex](7+4)^{2}[/tex]
[tex](-3-5)^{2} =64[/tex]
[tex](7+4)^{2} =121[/tex]
64+121= 185
Hope this helps...sorry if i'm wrong.
PROBLEM 1
Peter has many socks, all the same except that they are in three different colours. He is leaving to catch an early train to go on a business trip, and he does not want to wake his wife, so he packs in the
dark. He needs eleven pairs of socks, each sock in each pair the same colour. How many socks must he take from his drawer to be sure of achieving this?
Answer:
24 socks
Step-by-step explanation:
The given parameters are;
The number of different colors of socks = 3
Therefore, we have the worst case, the first three socks are different colors, since there are three different colors, the fourth socks is first pair in the worst case scenario
After which, every other two socks makes a pair in the worst case process, the number of socks he must take to make sure he has eleven pairs are given by the pairing table
Number of socks 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24
Number of pairs 0 0 0 1 1 2 2 3 3 4 4 5 5 6 6 7 7 8 8 9 9 10 10 11
Therefore, he must take 24 socks to make sue he has 11 pairs of the same color.

Tyler and Ilan scored 48% of their team’s points in the math
competition. If they scored 84 points, what was the team’s total score?
Answer:
Tyler and llan scored 24 points.
Explanation:
Another way to state this problem is what is 48% of 50.
"Percent" or "%" means "out of 100" or "per 100", Therefore 48% can be written as
48
100
.
When dealing with percents the word "of" means "times" or "to multiply".
Finally, lets call the number we are looking for "n".
Putting this altogether we can write this equation and solve for n
while keeping the equation balanced:
n=48,100 × 50
n = 24,001,00
n= 24

a mercury thermometer records a temperature of 8 degrees fahrenheit at 10 a.m. if the temperature drops by 3 degrees fahrenheit every hour what will be the temperature by 2 p.m. of the same day
Answer:
-4 Degrees Fahrenheit
Step-by-step explanation:
Given
[tex]Initial\ Temperature = 8[/tex] ---- at 10am
[tex]Difference = -3[/tex]
Required
Determine the final temperature at 2pm
First, we need to determine the hour from 10am to 2pm (Both inclusive)
[tex]Interval = 2pm - 10am + 1hr[/tex]
[tex]Interval = 4hr + 1hr[/tex]
[tex]Interval = 5hr[/tex]
To solve further, we make use of the following Arithmetic Progression formula:
[tex]T_n = a + (n - 1)d[/tex]
Where
[tex]a = 8[/tex] --- Initial
[tex]d = -3[/tex] --- difference
[tex]n = 5[/tex] -- 5th term
[tex]T_n[/tex] --- Final temperature at 2pm
So: we have:
[tex]T_n = 8 + (5 - 1) * -3[/tex]
[tex]T_n = 8 + (4) * -3[/tex]
[tex]T_n = 8 + 4 * -3[/tex]
[tex]T_n = 8 -12[/tex]
[tex]T_n = -4[/tex]
Hence:
The temperature is -4 Degrees Fahrenheit

Triangle X Y Z is shown. The length of side X Y is (9 n + 12) feet and the length of side X Z is (15 n minus 6) feet. Angles X Y Z and Y Z X are congruent. Consider isosceles ΔXYZ. What is the value of n? What is the measure of leg XY? ft What is the measure of leg XZ? ft
Answer:
[tex]n = 3[/tex]
[tex]XY = 39[/tex]
[tex]XZ = 39[/tex]
Step-by-step explanation:
Given
[tex]XY = 9n + 12[/tex]
[tex]XZ = 15n - 6[/tex]
[tex]<XYZ = <YZX[/tex]
Solving (a): n
To solve for n;
We make use of
[tex]XY = XZ[/tex]
Substitute values for XY and XZ
[tex]9n + 12 = 15n - 6[/tex]
[tex]9n - 15n = -12 - 6[/tex]
[tex]-6n = -18[/tex]
Divide through by -6
[tex]n = 3[/tex]
Solving (b) XY
[tex]XY = 9n + 12[/tex]
Substitute 3 for n
[tex]XY = 9 * 3 + 12[/tex]
[tex]XY = 27 + 12[/tex]
[tex]XY = 39[/tex]
Solving (c): XZ
[tex]XZ = XY[/tex]
[tex]XZ = 39[/tex]
The value of n is 3, the measure of leg XY is 39 ft, and the measure of XZ is 39 ft and this can be determined by using the properties of an isosceles triangle.
Given :
Triangle X Y Z is shown. The length of side X Y is (9 n + 12) feet and the length of side X Z is (15 n minus 6) feet. Angles X Y Z and Y Z X are congruent. Consider isosceles ΔXYZ.Given that the angle XYZ and angle YZX are congruent to each other and triangle XYZ is an isosceles triangle.
From the above statement, it can be concluded that the side length of XY and the side length of XZ is also congruent to each other, that is:
XY = XZ
9n + 12 = 15n - 6
Simplify the above expression in order to determine the value of 'n'.
18 = 6n
n = 3 ft
The measure of leg XY is given by:
XY = 9(3) + 12 = 39 ft
The measure of leg XZ is given by:
XZ = 15(3) - 6 = 39 ft
