Answer:
29) discriminant is positive
30) discriminant is 0
31) discriminant is negative
Step-by-step explanation:
the graph of a quadratic function y=ax^2 + bx + c is shown. Tell whether the discriminant of ax^2 + bx + c = 0 is positive, negative, or zero.
In the graph of question number 29 we can see that the graph intersects the x axis at two points
so the equation has 2 solutions.
When the equation has two solution then the discriminant is positive
In the graph of question number 30 we can see that the graph intersects the x axis at only one point
so the equation has only 1 solution.
When the equation has only one solution then the discriminant is equal to 0
In the graph of question number 30 we can see that the graph does not intersects the x axis
so the equation has 2 imaginary solutions.
When the equation has two imaginary solutions then the discriminant is negative

Answer:
They have 62 cookies left
Step-by-step explanation:
6 X 15 = 90
90 - 28 = 62
LCM for 15 and 20 is 60.
Here, let's use 20. Add it by 20 and you'll get 40. 15 is not a multiple of 40, so we add 20 to 40 again. 60 is a multiple of 15.
15 x 4
