Answer:
Therefore, the solutions of the quadratic equations are:

The graph is also attached.
Step-by-step explanation:
The solution of the graph could be obtained by finding the x-intercept.

Finding the x-intercept by substituting the value y = 0
so

∵ y = 0












So, when y = 0, then x values are 3, and 5.
Therefore, the solutions of the quadratic equations are:

The graph is also attached. As the graph is a Parabola. It is visible from the graph that the values of y = 0 at x = 5 and x = 3. As the graph is a Parabola.

Answer:
11.59x² -7.66x + 9.85
Step-by-step explanation:
3.63x² - 4.54x + 7.96x² +9.85 -3.12x
11.59x² -7.66x + 9.85
Answer:
5 drinks
Step-by-step explanation:
If the drinks cost $2.32 and you have $13 you can divide 13 by 2.32
13/2.32+ 5.6034...
You cannot buy a partal drink so you look at only the whole number which is 5.
