If you divide what she spent (2.65) buy the price per ounce (0.25) , you should come up with 10.6 ounces, which is the amount she bought.
Hope this helps :)
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)
Step-by-step explanation:
The x-intercept is the point where the graph touches the x-axis, which means y=0. So let's set y=0 in your equation, and we receive
(x-5)^2 + (0+12)^ = 169
which means
(x-5)^2 = 25
Solve this, and get x=10 or x=0.
This means the x-intercepts are (10,0) and (0,0).
Try doing the same for y.
