Answer:
Option D.
Step-by-step explanation:
The given quadratic equation is

We need to draw the graph of given equation by using graphing calculator as shown below.
From the graph it is clear that the parabola intersect the x-axis at points (-2,0) and (-5,0). So, the x-intercepts are (-2,0) and (-5,0).
Therefore, the correct option is D.
The answer you are looking for is 2 4/5. Hope this helps.
we know that
the formula to calculate the slope between two points is equal to

in this problem we have

substitute the values in the formula



therefore

Answer:
b
Step-by-step explanation:
If there are 40 children aged twelve and under and x of them are under three years old, 40 - x aged three twelve years old. From the 92 people that where taken by the company on whale watching trips, 52 are over twelve years old. The equation that best show the total cost, C is
(40 - x)(36) + (52)(48) = C
Rearranging the equation gives,
x = 40 - ((C - 2496)/ 36)
