Okay, so -
We have one very important thing here. This little part <em>6 - (-3). </em>
Now, it's essential to remember that when we have two negatives like this, we simply draw a line straight down. It becomes a positive!
So, our question is essentially <em>5 + 6 + 3 - 8 + 4 - 3 = ?</em> instead of <em>5 + 6 - (-3) - 8 + 4 - 3!</em> =)
With that in mind, we simply solve left to right.
<em>11 + 3 - 8 + 4 - 3 = ?</em>
<em>14 - 8 + 4 - 3 = ?</em>
<em>6 + 4 - 3 = ?</em>
<em>10 - 3 = ?</em>
<em>7</em> is our final answer! =)
Answer:
first you'd need to divide 7.50 by 6 which will get you (7.50÷6=1.25) then you would need to multiply 1.25 by 50 which will get you $62.50 (1.25×50=62.5).
Using Descartes' Rule of Signs:
The signs are: - + - + - +
There are 5 signs changes in this sequence, so there could be either 5, 3, or 1 positive roots.
If we negate the terms with odd numbers (x^5, x^3), we end up with the signs: - - - - - +
Since there is 1 sign change, there can be only 1 negative root.
This means the positive and negative roots can either be 6, 4, or 2.
Since the total number of roots cannot exceed 6, there are either 0, 2, or 4 complex roots.
Answer:
B.2
Step-by-step explanation:
g(1) if g(x) =x^2+1
= x^2 + 1 = (1)^2 + 1 = 1 + 1 = 2
The commutative property is a property of <em>addition</em>, not of <em>subtraction</em>. It can work in a subtraction problem if you keep the sign with the number, so you're adding positive and negative numbers.
3 - 6 + 5
= (3) + (-6) + (5)
= (3) + (5) + (-6)
= 3 + 5 - 6
