find the value of k if: (2x − y) 2 − (2x + y) 2 = 4xyk
(2x−y)(2)−(2x+y)(2)=4xyk
4kxy = -4y
4kxy/4xy = -4/4xy
k = -1/x

Which of the following relations are not functions? Select all that apply. {(1, 3), (3, 7), (5, 11), (7, 15), (9, 19)} {(1, 3), (1, 7), (5, 11), (5, 15), (9, 19)} {(−2, 4), (−1, 1), (0, 0), (1, 1), (2, 4)} {(2, 4), (1, 1), (0, 0), (1,−1), (2, −4)} {(6, 3), (4, 1), (2, 1), (0,−1), (−2,−3)} {(1, 3), (3, 7), (3, 11), (7, 15), (9, 19)} {(1, 3), (3, 7), (5, 11), (9, 15), (9, 19)}
Given:
7 relations are given.
To find:
The relation which is not a function.
Step-by-step explanation:
A relation is called function if there exist unique output for each input.
It means, each x-value has only one y-value.
{(1, 3), (3, 7), (5, 11), (7, 15), (9, 19)}, it is a function.
{(1, 3), (1, 7), (5, 11), (5, 15), (9, 19)}, it is not a function because there exist two y-values y=3 and y=7 at x=1.
{(−2, 4), (−1, 1), (0, 0), (1, 1), (2, 4)}, it is a function.
{(2, 4), (1, 1), (0, 0), (1,−1), (2, −4)},it is not a function because there exist two y-values y=4 and y=-4 at x=2.
{(6, 3), (4, 1), (2, 1), (0,−1), (−2,−3)}, it is a function.
{(1, 3), (3, 7), (3, 11), (7, 15), (9, 19)}, it is not a function because there exist two y-values y=7 and y=11 at x=3.
{(1, 3), (3, 7), (5, 11), (9, 15), (9, 19)}, it is not a function because there exist two y-values y=15 and y=19 at x=9.
Therefore, the correct options are 2, 4, 6 and 7.
please help me with this question
Step-by-step explanation:
The river is 1000 m wide, and the boat moves at 3 m/s, so the time it takes to cross the river is:
t = (1000 m) / (3 m/s)
t = 333.3 s
The river flows at 2 m/s, so by the time he reaches the other bank, he drifts downstream a distance of:
d = (2 m/s) (333.3 s)
d = 666.7 m

Simplify this expression 4x^2y^3 x 2x^3y^4
Answer:
8 x^5 y^7
Step-by-step explanation:
Simplify the following:
4×2 x^2 y^3 x^3 y^4
Hint: | Combine products of like terms.
4 x^2 y^3×2 x^3 y^4 = 4 x^(2 + 3) y^(3 + 4)×2:
4×2 x^(2 + 3) y^(3 + 4)
Hint: | Evaluate 3 + 4.
3 + 4 = 7:
4×2 x^(2 + 3) y^7
Hint: | Evaluate 2 + 3.
2 + 3 = 5:
4×2 x^5 y^7
Hint: | Multiply 4 and 2 together.

Answer:
[tex]\angle {1} = 90\\\angle {2} = 45\\\angle {3} =55[/tex]
Step-by-step explanation:
1 is 90 because it's placed onto a straight line the equals 180 degrees, therefore it's 90 because the other 2 angles with it are the same, meaning that they had to be 45. 3 is 55 because 90+35=125, and the sum of all 3 angles in a triangle must equal 180, therefore 180-125=55.

A man is walking at the speed of 34km/hr.In 30 min he will walk :
a) 1/4km b)1/3km c1/2km d)1.5km
Answer:
All choices are incorrect
30 min= 1/2
34x1/2
17
Answer=17 km in 30 min
Answer:
See below.
Step-by-step explanation:
This problem and the answers don't work.
The way the problem is written, the answer is 17 km.
There is no such answer.
There is a mistake somewhere.
If the man is walking at the speed of 3/4 km/h, then in 30 minutes, which is half of 1 hour, he walk 3/8 km. There is no answer of 3/8 km in the choices.
Please check on the problem and post it correctly.
If ST=w–47 and RU=w–63, what is the value of w?
Answer:
w = 79
Step-by-step explanation:
We know that RU us a midsegment so it must be 1/2 of ST.
So ST = 2RU.
w-47 = 2(w-63)
w-47 = 2w-126
-w = -79
w = 79

Answer:
option A is correct
75 − s = c
20s + 30c = 1,870
Step-by-step explanation:
The question is not complete.
Here is a complete form
"A software company is selling a new game in a standard edition and a collector's edition the box of the standard edition has a volume of 20 cubic inches and the box for the collector's edition has a volume of 50 cubic inches 30 cubic inches the company received an order for 75 copies of the game, and the total volume of the order to be shipped is 1,870 cubic inches. Which of the following systems of equations can be used to determine the number of standard edition games, s, and collector’s edition games, c, that were ordered?"
s+c=75
75 − s = c
20s + 30c = 1,870
the options are
A. 75 − s = c
20s + 30c = 1,870
B. 75 − s = c
30s + 20c = 1,870
C. s − c = 75
25(s + c) = 1,870
D. s − c = 75
30s + 20c = 1,870

Step-by-step explanation:
Kiran ate breakfast in a café. His total check was $15.
a. What’s a 20% tip?
b. How much money did Kiran spend altogether for breakfast?
Answer:
A 20 percent tip is basically multiplying the price by 0.2
Percent means out of a hundred.
20/100 is 0.2
We have to find 0.2 of 15.
We can multiply 15 by 0.2 to find 20 percent of 15 and you would get 3.
20 percent of 15 is 3 dollars thats your answer to A
Now the total price would just be the percentage you found in A and add it to the total breakfast.
3 + 15 = 18
Kieran spend 18 dollars for brekfast.
A recipe says to use 3.5 cups of flour to make 48 cookies. What is the constant of proportionality that relates the number of cookies made, y, to the number of cups of flour used, x. Round your answer to the nearest tenth.
Answer: 0.07 cups/cookie
Step-by-step explanation:
The Constant of proportionality is the measure by which the number of cookies made, y increases to the number of cups of flour used, x.
If 3.5 cups of flour makes 48 cookies then how many cookies does 1 cup make;
= 3.5/48
= 0.07 cups/cookie
