Hello there. =)
<span>Ann is grouping 38 rocks .she can put them into groups of 10 rocks or as single rocks. what are the different way Ann can group the rocks?
</span><span>2 groups of 19</span>
we need the equation or graph to figure that out
The equation of a parabola that opens up and has the following x intercepts (-3,0) and (4,0) is 
<h3><u>Solution:</u></h3>
We have to find the equation of a parabola that opens up and has the following x intercepts (-3, 0) and (4, 0)
x-intercepts of the parabola are (−3, 0) and (4, 0)
So, we can form an equation:
Also x = 4
x – 4 = 0
x – 4 = 0 is another factor of quadratic equation.
The quadratic function is:

Hence, the equation of the parabola is 
7 is the independent variable in this equation because it is a constant, it does not change in any case.
It is money nickels are 5 , dimes are are 10, pennies are 1, and quateres are 25 just add them up
