There is no restriction upon x for that function therefore the domain is all real numbers. x=(-oo, +oo)
Answer:
c
Step-by-step explanation:
The median is half the sum of the parallel bases, that is
UV =
3 + 20x = ( multiply both sides by 2 to clear the fraction )
6 + 40x = 15 + 31x ( subtract 31x from both sides )
6 + 9x = 15 ( subtract 6 from both sides )
9x = 9 ( divide both sides by 9 )
x = 1
Then
UV = 3 + 20x = 3 + 20(1) = 3 + 20 = 23 → c
3/5 - 1/6
18/30 - 5/30 = 13/30
There is 13/30 of milk remaining

Answer:
Option (C)
Step-by-step explanation:
Given expression is 4(x + x + 7) - 2x + 8 - 4
When x = 1,
Value of the expression will be,
= 4(1 + 1 + 7) - 2(1) + 8 - 4
= 4(9) - 2 + 8 - 4
= 36 - 2 + 8 - 4
= 38
For x = 2,
= 4(2 + 2 + 7) -2(2) + 8 - 4
= 44 - 4 + 8 - 4
= 44
Now we will check the same for the given options.
Option (A). For x = 1,
6x + 11 = 6(1) + 11
= 17
For x = 2,
6x + 11 = 6(2) + 11
= 23
Option (B). For x = 1,
3(x + 7) = 3(1 + 7)
= 24
For x = 2,
3(x + 7) = 2(2 + 7)
= 18
Option (C), x = 1
2(3x + 16) = 2[3(1) + 16]
= 38
For x = 2,
2(3x + 16) = 2[3(2) + 16]
= 44
Option (D), For x = 1,
= 19
For x = 2,
2(3x + 16) = 2[3(2) + 16]
= 44
Since value of the expression for x = 1 and 2 matches with the value in option (C)
Therefore, Option (C) will be the answer.
