Answer:
Step-by-step explanation:
Given that,
Center = (2,-9)
Radius of the circle, r = 7
We need to find the equation of a circle with a center at (2, -9) and a radius of 7. It can be given by :
Put h = 2, k = -9 and r = 7 So,
Hence, this is the required solution.
Answer:
x=-5
Step-by-step explanation
The first box has eight x's and six 1's which means that it would be written as 8x+6
The second box has four x's and fourteen -1's which means that it would be written as 4x-14
You set them equal to one another
8x+6=4x-14
You subtract 4x from both sides
4x+6=-14
Subtract 6 on both sides
4x=-20
Divide 4 on both sides
x=-5

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)
