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:
One person is pushing the car in the net force of 200N
Step-by-step explanation:
600 divided by 3 (600 N in total, and 3 person pushing.)
The answer is -1 because when cross simplifying you get 0/2-2/0 which =-2/2 and that simplified is -1
The answer is -1
do order of operations:
60 / 5*(7-5)=
do parenthesis first: 7-5=2
60 / 5*2 =
now do division: 60/5 =12
12*2 =
now multiply: 12 *2 = 24
answer is 24
