Answer:
Quadratic trinomial
Step-by-step explanation:
(8x^2 + 3x) - (12x^2 - 1)
= 8x^2 + 3x - 12x^2 + 1
= 8x^2 - 12x^2 + 3x + 1
= -4x^2 + 3x + 1
^ ^ ^
1 2 3
So the answer is Quadratic trinomial

Plot a graph
First, we need to determine the minimum and maximum values of x and y
For x:
Minimum = 0
For maximum; Let y = 0
Solve for x
For y:
Minimum = 0
For maximum; Let x = 0
Solve for y

Answer:
Step-by-step explanation:
One solution: when two lines intersect in exactly one point.
Infinitely many solutions: When one of two lines can be shown algebraically to be exactly the same as the other. The two lines coincide.
No solution: The two lines have the same slope but different y -intercepts. They can't and don't intersect.
Answer:
-2
Just put the point to -2.
