Answer:
Slope: -5
y-Intercept: -1
Step-by-step explanation:
In the equation y = mx + b (its the form of a linear equation) the slope is m and the y-intercept is b. Comparing that to the problem, we can see that m = -5 and b = -1. So, the slope is -5 and the y-intercept is -1.
1 nanometer = 1 * 10^9 meters
so 1 nanometer = 1 * 10^7 centimeters
375 nanometers = 3,75 * 10^5 centimeters
Answer: The selling price was $195,200
Step-by-step explanation:
Given:
Tax paid = $488
Rate = $1 per $400 = 1/400
Using the formula;
Tax = rate × selling price
Selling price = tax /rate
Selling price = $488/(1/400) = $488×400 = $195200
Answer:
<em>The width is 4 cm</em>
<em>The length is 12 cm.</em>
Step-by-step explanation:
<u>Area of a rectangle</u>
Given a rectangle of width W and length L, its area is calculated as follows:

The area of the given rectangle is 48 cm^2, and the length is three times the width, thus:
L = 3W
Substituting into the formula of the area:


Simplifying:

Solving:


The width is 4 cm. Find the length:
L=3W=3*4= 12
The length is 12 cm.
The image attached shows the rectangle on the centimeter grid
(3^2)3=27
27/3^x=3
3(3^x)=27
3^x=9
x=2
