What are the coordinates of D’ when the quadrilateral is reflected across the line y = x?
On a coordinate plane, quadrilateral A B C D has points (1, 2), (2, 4), (4, 3), (3, 1).
(1, 3)
(2, 4)
(3, 4)
(1, 1)
Answer:
(1, 3)
Step-by-step explanation:
If quadrilateral ABCD is reflected across the line y = x, then the x- and y-coordinates get reversed. Since the coordinates of point D are (3, 1), then the coordinates of point D' are (1, 3).

Step-by-step explanation:
Víctor claims that when 1/6 is divided by a fraction the result will always be greater than 1/6 find an example of a fraction that supports victors claim and an example of a fraction that contradicts victors claim
Answer:
Step-by-step explanation:
Choose a random fraction less than 1. I will choose 1/4.
1/6 ÷ 1/4 = 1/6 × 4/1 = 4/6 = 2/3
2/3 > 1/6 so this example supports his claim.
Now chose a fraction greater than 1. I will choose 4/3
1/6 ÷ 4/3 = 1/6 * 3/4 = 3/24
3/24 < 1/6 so this contradicts his claim
Simplify: x^2y-5 * x^y+8
what is 60 /−3 and how do you solve
Answer:-20
Step-by-step explanation:
First divide 60 by 3 as you would regularly.
Your answer should be 20
Make sure to remember when multiplying with integers:
negative x negative = positive
positive x positive = positive
negative x positive = negative
positive x negative = negative
Make sure to remember when dividing with integers:
positive / positive = positive
negative / negative = positive
positive / negative = negative
negative / positive = negative
Because this question is a "positive / negative" your answer would be negative. Therefore your answer is -20
I hope this helps! :)

Answer:
B. 4/3
Step-by-step explanation:
[tex] \frac{ {4}^{ - 3} . {3}^{4} . {4}^{2} }{ {3}^{5} . {4}^{ - 2} } \\ \\ = \frac{ {4}^{ - 3} . {4}^{2 + 2} }{ {3}^{5 - 4}} \\ \\ = \frac{ {4}^{ - 3} . {4}^{4} }{ {3}^{1}} \\ \\ = \frac{ {4}^{4 - 3} }{ {3}^{1}} \\ \\ = \frac{ {4}^{1} }{ {3}^{1}} \\ \\ = \frac{4}{3} [/tex]
Answer:
B. 4/3

A students cost for last semester at her community college was 2100 she spent 231 of that on books what percent of last semesters college costs was spent on books
Work Shown:
Divide the two amounts, smaller over bigger, to get
231/2100 = 0.11
Then move the decimal point over two spots to the right to get to 11%
Note how 11% of 2100 = 0.11*2100 = 231.

Combine like terms (t): 14t + 5.1There are 874 pieces of candy in the piñata. There are 23 children at the party, and they all agreed to split the candy equally. How many pieces of candy will each child receive?
Answer:
38 candies.
Step-by-step explanation:
Given the following data;
Total number of candy = 874
Total number of children = 23
Since we know that they are all sharing it equally, each child would get;
Each child = 874/23
Each child = 38 candies.

what value is equivalent to 108-8x(5-2)-60
Answer:
-28 + -1 = -29
-14 + -2 = -16
-7 + -4 = -11
-4 + -7 = -11
-2 + -14 = -16
-1 + -28 = -29
1 + 28 = 29
2 + 14 = 16
4 + 7 = 11
7 + 4 = 11
14 + 2 = 16
28 + 1 = 29
Step-by-step explanation:
Answer:
6/7
Step-by-step explanation:

Answer:
1) 4
2) 2
3) 5
4) 8
Step-by-step explanation:
All you have to do in this question is to substitute what they are telling you.
First blank:
They told us that m is 0 so if we plug that into the equation we can get s.
[tex]2m+4s=16\\2(0)+4s=16\\4s=16\\s=4[/tex]
In this one if m is 0, s will have to be 4.
Second blank:
They told us that s is 3 so if we plug in that into the equation we can get m.
[tex]2m+4s=16\\2m+4(3)=16\\2m+12=16\\2m=4\\m=2[/tex]
In this one if s is 3, m will have to be 2.
Third blank:
They told us that m is -2 so if we plug that into the equation we can get s.
[tex]2m+4s=16\\2(-2)+4s=16\\-4+4s=16\\4s=20\\s=5[/tex]
In this one if m is -2, s will be 5.
Fourth blank:
They told us that s is 0 so if we plug into the equation we can get m.
[tex]2m+4s=16\\2m+4(0)=16\\2m=16\\m=8[/tex]
In this one if s is 0, then m will be 8.

one number is three times another, and four times the smaller added to five times the greater amounts to 133; find them
Step-by-step explanation:
S=smaller number; L=larger number=3S
.
4S+5L=133
4S+5(3S)=133
4S+15S=133
19S=133
S=7 ANSWER 1: The smaller number is 7.
.
L=3S=3(7)=21 ANSWER 2: The larger number is 21.
.
CHECK:
4S+5L=133
4(7)+5(21)=133
28+105=133
133=133
The diagonals of a quadrilateral QRST intersect at P(2,3). QRST has vertices at Q(3,6) and R(-3,5). What must be the coordinates of S and T to ensure that QRST is a parallelogram?
Answer:
S (1 , 0)
T (7 , 1)
Step-by-step explanation:
If QRST is a parallelogram, P is the mid point of segment QS and segment RT.
Basic formula for mid-point of segment: ((x1+x2)/2 , (y1+y2)/2)
T (x₁ , y₁) S (x₂ , y₂) P (2 , 3) Q (3 , 6) R (-3 , 5)
2 = (x₁ + (-3))/2 x₁ = 7
3 = (y₁ + 5)/2 y₁ = 1
T (7 , 1)
2 = (x₂ + 3))/2 x₂ = 1
3 = (y₂ + 6)/2 y₂ = 0
S (1 , 0)

Melanie has a ribbon that is 18 inches long. She cut the ribbon into 3 equal pieces. Then she cut each of those pieces in half. How many small pieces of ribbon are there? how long is each pieces
Answer:
I guess there are 6 small pieces but dont know how long they are sry
Answer:
12 small piece of ribbon, each 3/2 inches long
Step-by-step explanation:
one 18" long ribbon divided into 3 equal pieces will produce three 6 inch ribbons
three 6" ribbons, each one cut in half (or divided by 2), equals 12 pieces
each one being 18/12 inches long; which reduces to 3/2

the graph shows the cost of some taxi journeys. work out a formula for C in terms of n.
Given:
The graph of cost of taxi with respect to number of miles.
To find:
The formula for C in terms of n.
Solution:
In the given graph x axis represents the number of miles (n) and y-axis represents the cost of taxi (C).
From the given graph it is clear that, the line passes through the points (0,3) and (5,6). So, the equation of line is
[tex]y-y_1=\dfrac{y_2-y_1}{x_2-x_1}(x-x_1)[/tex]
[tex]y-3=\dfrac{6-3}{5-0}(x-0)[/tex]
[tex]y-3=\dfrac{3}{5}(x)[/tex]
Adding 3 on both sides, we get
[tex]y=\dfrac{3}{5}x+3[/tex]
Putting y=C and x=n, we get
[tex]C=\dfrac{3}{5}n+3[/tex]
Therefore, the required formula is [tex]C=\dfrac{3}{5}n+3[/tex].
