Answer:

Step-by-step explanation:

Reduce the exponent of x.

Use the negative exponent rule: 

Use the rational exponent rule: ![a^\frac{m}{n} = \sqrt[n]{a^m}](https://tex.z-dn.net/?f=%20a%5E%5Cfrac%7Bm%7D%7Bn%7D%20%3D%20%5Csqrt%5Bn%5D%7Ba%5Em%7D%20)

You would have to change that 5% into 0.05 and multiple it by 2 you get 0.1.Now,multiple 0.1 by 20000 and you get 2000.
Answer:
Slope = -2
Step-by-step explanation:
Given the two points, (-4, 10) and (0, 2), the error in the given problem is the incorrect substitution of values into the formula. It should have been formatted as follows:
Let (x₁, y₁) = (-4, 10)
(x₂, y₂) = (0, 2)
The formula for solving for the slope of the line is:
m = (y₂ - y₁)/(x₂ - x₁)
where <em>m</em><em> </em>represents the <u>slope</u> of the line.
Substitute the given values into the formula to solve for the slope:
m = (y₂ - y₁)/(x₂ - x₁)


m = -8/4
m = -2
Therefore, the slope of the line is -2.
The discount was
15%×$275 = $41.25
so the price at which the system was sold was
$275.00 - 41.25 = $233.75
The sales person receives 2% of this, or
2%×$233.75 ≈ $4.68
Y varies with x² times a constant. We will call the constant a
144=ax²
144 = a(4²)
144 = 16a
a = 9
Apply our equation y = 9x²
y = 9(-5)²
y = 9* 25
y=225
Answer is B
