Slope of the equation is -9/2
Step-by-step explanation:
- Step 1: Write the equation in slope-intercept form y = mx + b
9x + 2y = 9
2y = -9x + 9
y = -9/2 x + 9/2
⇒ Slope, m = -9/2
According to the question, the equation
is the algebraic equation as well as polynomial equation. Using square root principles, the equation can be re-write.
The factors of the denominator term is not possible and it cannot be simplified. And the simplification is possible with the concept of complex number.
What is polynomial expression?

To find how much each percentage is you need to make each one a fraction so 3/100 x 26000/1 your answer is 780 for 3 percent so her first raise makes it 26780 and 26000 plus 26780 is 52780 then keep adding 780 to 26000. So your answer would be A i think
A) 0.9803; 0.4803
B) 32
We calculate the z-score for this problem by using the formula:

Using our formula, we have:

Using a z-table (http://www.z-table.com) we see that the area to the left of, less than, this score is 0.9803.
To find the probability it is between the mean and this, we subtract the probability associated with the mean (0.5) from this:
0.9803 - 0.5 = 0.4803.
To find B, we first find the z-score for this. Using a z-table (http://www.z-table.com) we see that the closest z-score would be 2.33. We then set up our equation as

Multiplying both sides by 0.85 we have
2.33(0.85) = 0.35√n
1.9805 = 0.35√n
Divide both sides by 0.35:
1.9805/0.35 = √n
Square both sides:
(1.9805/0.35)² = n
32 ≈ n

526 + x = 650
x = 650 - 526
x = 124
