Answer:
Step-by-step explanation:
Number 5 is L because you have 18 coins but you only want to find the probability of the pennies. So take 3/18 and simplify to 1/6 by dividing both the numerator and the denominator by 3.
Number 6 can be (-6x - 3), just use the distributive property on the original expression.
Correct answer in this scenario would be D
Answer:
v =-28
Step-by-step explanation:
-18 - 3 /4 v = 3
Add 18 to each side
-18+18 - 3 /4 v = 3+18
-3/4 v = 21
Multiply each side by -4/3 to isolate v
-4/3 *-3/4v = 21*-4/3
v =-28
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
