Any fraction that does not equal 1/2.
Answer:
This quadratic equation has 2 solutions.
Step-by-step explanation:
I assume the '?' in your question is meant to be power 2 (²), or else it would not be a quadratic equation. You could write it using the superscript version of 2.
We can solve this equation by expressing it in the form: ax² + bx + c
x² + 9x= -8
x² + 9x + 8 = 0
Now if you know the discriminant, you can simply plug in your values of a, b, and c to see how many solutions there are.
In this case, you would not need the discriminant as there are whole-number factors and hence this can simply be factorised.
x² + 9x + 8 = 0
(x + 8)(x + 1) = 0
For this equation to be true (= 0), x can equal -8 OR -1.
Hence, this quadratic equation has 2 solutions.
Answer:
Slope of line 1 = 3
Slope of line 2 = -3

You know the following information:
1. The amount of money (in dollars) earned last year was:

2. The amount of money (in dollars) earned this year, is:

Then, to estimate the sum (the total amount of money the Software Company earned in those two years, you can round the numbers to the nearest billion.
Having:

You need to look at the digit located in the Hundred millions place. Notice that this is:

Then, since:

You need can't round up. Then:

Now, having:

You can identify that the digit in the Hundred millions place is

Therefore:

Now you can add the numbers rounded:

Hence, the answer is: Option B.
