Standard form: ax^2 + bx + c = y
Steps to simplify:
2x^2 - 1 = 3x + 4
~Subtract (3x + 4) to both sides
2x^2 - 1 - 3x + 4 = 3x + 4 - 3x + 4
~Simplify
2x^2 - 3x - 5 = 0
(a = 2, b = -3, c = -5)
Now that we know what these values are, we can use the quadratic formula to solve.

Answer: x = 5/2 or x = -1
Best of Luck!
Although A is correct, C is the correct answer. If you don't get a problem like this, try to draw some of the shapes out and then draw a symmetrical line down the middle to find out if it is symmetrical.
Answer:
True?
Step-by-step explanation:
I think its true but I'm not 100% sure so I would go with true. Try thinking of your past problems that you used and think about that maybe? But in then mean time, I would go with True
Answer:
Check Explanation and the attached image.
Step-by-step explanation:
The histogram of the set of data presented is presented in the attached image to.this solution
The histogram represents data by indicating the frequency of distribution on the y-axis and the sets of variables indicated on the x-axis.
With the constellations named numbers 0 to 6, the frequency of each constellation, that is, the number of stars in each constellation corresponds to the height of the bar representing each constellation.
Hope this Helps!!!
Answer:
Positive 3
Step-by-step explanation:
you have to add 4 and -9 first and you get -5 then you add that to positive 8 and get 3
