The set does not represent a function, option (D) the set is a not function since each element in the range has a different element in the domain is correct.
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.
We have a set of ordered pairs:
{(0,1.2),(3,2),(-1.2,3), (4, -2),(1,-1.2),(1,2,4)}
We know there are four main types of mapping that are:
One to one, one to many, many to one, and many to many.
In the case of one to one, and many to one. the relation is a function but in the case of one to many and many to many relations is not a function.
As we can see in the set of ordered pairs the x values are repeated which is also not a property of a function hence it is not representing the function.
Thus, the set does not represent a function, option (D) the set is a not function since each element in the range has a different element in the domain is correct.

The sum of three consecutive odd integers is fifty-one. Find the integers. (Enter your answers as a comma-separated list.)
Answer:
15, 17, 19
Step-by-step explanation:
let the first odd number be n then the next 2 are n + 2 and n + 4 , then
n + n + 2 + n + 4 = 51
3n + 6 = 51 ( subtract 6 from both sides )
3n = 45 ( divide both sides by 3 )
n = 15
Then
n + 2 = 17 and n + 4 = 19
The 3 consecutive odd numbers are 15, 17, 19
f(x)= 2x +6 , vertical shrink by a factor of 1/2
Answer:
g(x) = x+3.
Step-by-step explanation:
i hope this helps :D
When a function is shrunk vertically, the function has undergone a form of transformation.
The resulting function when [tex]f(x) = 2x + 6[/tex] vertically shrink by 1/2 is [tex]f'(x) = x + 3[/tex]
Given that:
[tex]f(x) = 2x + 6[/tex]
[tex]k = \frac 12[/tex] --- shrink factor
When a function is shrunk vertically, the rule of transformation is:
[tex](x,y) \to (x,ky)[/tex]
So, we have:
[tex]f'(x) = k f(x)[/tex]
The new function becomes
[tex]f'(x) = \frac 12 \times (2x + 6)[/tex]
[tex]f'(x) = x + 3[/tex]
Hence, when [tex]f(x) = 2x + 6[/tex] is vertically shrunk by 1/2, the new function is [tex]f'(x) = x + 3[/tex]

Given:
The table of values.
v and x are in direct proportion.
To find:
The formula connecting v and x.
Solution:
(a)
v and x are in direct proportion.
[tex]v\propto x[/tex]
[tex]v=kx[/tex] ...(i)
Where, k is the constant of proportionality.
Putting v=13.6 and x=32.64, we get
[tex]13.6=k(32.64)[/tex]
[tex]\dfrac{13.6}{32.64}=k[/tex]
[tex]\dfrac{5}{12}=k[/tex]
Putting the value of k in (i), we get
[tex]v=\dfrac{5}{12}x[/tex]
Therefore, the required formula that connecting v and x is [tex]v=\dfrac{5}{12}x[/tex].
(b)
Putting v=n and x=8.16, we get
[tex]n=\dfrac{5}{12}(8.16)[/tex]
[tex]n=3.4[/tex]
Therefore, the value of n is 3.4.

In one day, Ricardo hiked 2_ 2 3 times as far as Bernie and Chloe hiked before they ate lunch. How far did he hike?
Complete question :
Bernie and Chloe hiked the Tremont Trail to the end and back. Then they hiked the Wildflower trail to the end before stopping to eat lunch. Before Ricardo ate his lunch, he hiked 2 2/3 times as far as Bernie and Chloe. How far did he hike?
Required diagram is attached below
Answer:
25 miles
Step-by-step explanation:
Tremont Trail = 3 1/2 miles
Wildflower trail = 2 3/8 miles
Distance covered ; Tremont Trail and back : (3 1/2 * 2). = 7/2 * 2 = 14 /2 = 7 miles
Total distance covered by Bernie and Chloe before stopping for lunch /
(7 miles + 2 3/8 Miles) = 9 3/8 miles = 75/8 miles
Ricardo's distance = 2 2/3 * Bernie and Chloe's total distance
Ricardo's distance = 8/3 * 75/8 = 600 /24 = 25 miles

Divide both sides by -2
x + 5 = -10
x = -15
Answer: x = -15
Step-by-step explanation:
-2(x + 5) = 20
-2x - 10 = 20
Add 10 to both sides
-2x = 30
Divide both sides by -2
x = -15

Solve 2x + 20 = 6x – 12*
Answer:
x = 8
Step-by-step explanation:
Given
2x + 20 = 6x - 12 ( subtract 2x from both sides )
20 = 4x - 12 ( add 12 to both sides )
32 = 4x ( divide both sides by 4 )
8 = x
=> 2x + 20 = 6x - 12
=> 20 + 12 = 6x - 2x
=> 32 = 4x
=> x =32/4
=> x = 8need help asap..really need ur help
