Answer:
Step-by-step explanation:
25
We know that Heidi has x donations. We also know that Granpa has 2 fewer donations than Heildi, which means to subtract so x - 2. We also know that there are 7 donations in all. This tells use donations = 7 in all. So
Heidi donations = x
Grandpa = x - 2
Heidi + Grandpa = Total donations
x + (x-2) = 7
50 x 100 = 5000 so there for 5000 is 100x bigger
A quadratic function would fit this data.
The data does not increase at the same rate each time, so it is not linear. It comes to a maximum at (8, 150) and decreases. It decreases the same way it increased. This would lead to a U-shaped graph, which indicates a quadratic function.
SO, when a question says is it means equals. When it says of what it means multiply (usually). So, the beginning equation of this would be...
24.5/100 (x) = 15 (< also instead of putting (24.5/100) you could put .245)
to get rid of the (24.5/100) on the left side we multiply both sides by the reciprocal. So....
x = 15 (100/24.5)
x = 61.2244
Hope this helps!
