Answer:
9 points
Step-by-step explanation:
took the quiz edge2020
First find the slope of the line:-
= (0- - 9) / (3 - 0) = 9/3 = 3
Now use the point slope form of the equation to plug in the point (3,0):-
y - y1 = 3(x - x1)
y1 = 0 and x1 = 3:-
y - 0 = 3(x - 3)
y = 3x - 9 is the answer Its D.
Looking at each x and y in the graph, you can tell the graph is nonlinear.
If you plotted it, you would get a parabola.
In a linear function, the change in the variables would be constant.
For example, (-1, 5), (0, 3), (1, 1), etc.
Answer:
B -8
Step-by-step explanation:
The discriminant is b^2-4ac when the equation is in the form ax^2+bx+c
a=-3 b=-2 c=-1
b^2-4ac
(-2)^2 -4(-3)(-1)
4 -12
-8
Answer:
A right triangle
Step-by-step explanation:
A right triangle would meet these characteristics. A triangle's inner angles always add up to be 180 degrees. A right triangle has one angle at 90 degrees meaning the other two angles need to be less than 90 degrees and sum up to be 90 degrees. This would indicate that both of these angles' exterior angles would be obtuse because they would be wider than 90 degrees.
