The domain of 0 ≤ x ≤ 6 is x ∈ [0, 1, 2, 3, 4, 5, 6], and the range of the 0 ≤ y ≤ 6 is y ∈ [0, 1, 2, 3, 4, 5, 6].
What is a function?It is defined as a special type of relationship, and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.
The question is incomplete.
The complete question is in the picture, please refer to the attached picture.
0 ≤ y ≤ 72
The range will be y ∈ [0, 72]
0 ≤ x ≤ 72
The domain will be x ∈ [0, 72]
0 ≤ x ≤ 6
The domain will be x ∈ [0, 1, 2, 3, 4, 5, 6]
0 ≤ y ≤ 6
The range will be y ∈ [0, 1, 2, 3, 4, 5, 6]
Thus, the domain of 0 ≤ x ≤ 6 is x ∈ [0, 1, 2, 3, 4, 5, 6], and the range of the 0 ≤ y ≤ 6 is y ∈ [0, 1, 2, 3, 4, 5, 6].

Nicholas has 22 nickels, dimes, and quarters. There are 3
less dimes than quarters and 2 more dimes than nickels.
How much money does he have?
Answers
Nickels: 22
Dimes: 24
Quarters: 27
2 more dimes than nickels, we already know that there are 22 nickles so...
Dimes= 24
3 less dimes that quarters ^(we already know how many dimes).
All we have to do is add 3 to the amount of dimes!
Quarters 27
____________________________________________________________
Now to find the amount of money you have to find out what each coin equals and multiply the number of coins by the cost of each coin, and then by 100 because there are 100 cents in 1 dollar.
22 nickels*5/100= $1.10
24 dimes*10/100= $2.40
27 quarters*25/100= $6.75
1.10+2.40+6.75= $10.25
The amount of money he has in $10.25
4x – 2y = 2
x = y + 4
Answers
Answer:
y = -7 and x = -3
Step-by-step explanation:
Substitute x for y + 4 in the first equation and solve for y
4(y+4) - 2y = 2
4y + 16 - 2y = 2
16 + 2y = 2
2y = -14
y = -7
Then in order to find x, substitute y for -7 in the second equation
x = -7 + 4
x = -3
Answer:
x= -3, y= -7
Step-by-step explanation:
substitute x=y+4 in the first equation
4 (y+4) -2y =2 distribute
4y+16-2y=2 subtract both sides by 16
4y-2y=2-16 combine like terms
2y= -14 divide both sides by 2
y=-7
x=y+4 substitute y=-7
x= -7+4
x= -3

If the sides to a triangle are 20, 40, and 80 cem, is it Right triangle?
Answers
Answer: no
because using Pytago theorem, we have:
20² + 40² ≠ 80²
80² + 20² ≠ 40²
80² + 40 ² ≠ 20²
Step-by-step explanation:
Answer:
No, it does not follow the Pythagorean Theorem.
Step-by-step explanation:
A right triangle must follow the equation a^2 + b^2 = c^2 for its sides to be true. 20^2 + 40^2 = 2000.
the square root of 2000 equals about 44.7213595.
Thus, a triangle with sides 20, 40, and 80 is not a right triangle.
