Answer:Test one is 84% correct
Test two has a total of 20 questions
Test three he has 28 answers right
Step-by-step explanation:
The answer is B
I know this because 8 divided by -4 =-2
Therefore the answer is: B
The answer might be 45 x 1, because 45 is the greatest factor of 45.
If you want to know why tell me
Answer: 7.5 minutes
Step-by-step explanation: divide 30 by 4.
I'm not sure what method you are supposed to use to graph this. I would do it the following way although you can also change it to vertex form of the equation and graph it using (h,k) and "a".
The way I'd do it..
vertex (-b/2a , y)
-b/2a = -2
plug in this value for x to find the y coordinate.
-4 +8 -3 = 1
vertex (-2, 1)
the negative in front of the x^2 flips the parabola upside down
So you graph an upside down parabola at (-2,1). It's symmetrical, input easy to do points if needed like x=0 , x=-4
