When x = 1:
1³ + 1 - 3 = -1
When x = 2:
2³ + 2 - 3 = 7
Since f(x) = x³ + x - 3 is continuous, it follows from the intermediate value theorem that for some c in the interval (1, 2), we have f(c) = 0, since f(1) < 0 < f(2).
Answer : The value of x and y is 8 and 10 respectively.
Step-by-step explanation :
As we known that if two parallel lines are cut by a transversal line then consecutive interior angles are supplementary.
From the given figure we conclude that:
...........(1)

............(2)
...........(3)

...........(4)
Now we adding equation 2 and 4, we get the value of x.



Now we are putting the value of x in 4, we get the value of y.




Therefore, the value of x and y is 8 and 10 respectively.

ANSWER: [F] 36 Only 1 Answer!!!
No Explanation Provided!!!
We have the following data:
Under 3 years = 0 $
3 to 12 years = $ 34
Over 12 years = $ 45
103 people
There were 64 children aged 12 and under, of which some children were under 3 years
If x represents the number of children under 3 years
We have then that the equation is
34 * (64-x) + 45 (103-64) = C
answer
C = 34 * (64-x) + 45 (103-64)
Answer:

multiply x through out:

factorise out x²:

take square root on both sides:
