The graph below represents the price of sending text messages using the services of a phone company. What is the constant of pro
portionality? A. 12 B. 24 C. 46. D. 48
1 answer:
Ah, direct variation/proportion.
That is simply a linear equation with a y-intercept of 0.
So... let's solve this.
Simply put, a direct variation multiplies the x-value by a constant to get the y-value.
Let's take the point
on this graph and solve for the constant of proportionality:
We easily solve that and get our answer of

Answer: 100 square units.
Step-by-step explanation:
Given: Jernel has to figure out the area of her square garage.
She knows that one side of the garage is equal to the length of her rabbit pen.
Now, the length of the rabbit pen = 10 units
Then , the length of the garage will be 10 units
Now, Area of square =
Hence, the area of the garage = 100 square units.
Answer:
Step-by-step explanation:
Given:
Required:
LCM of the polynomials
SOLUTION:
Step 1: Factorise each polynomial
Step 2: find the product of each factor that is common in both polynomials.
We have the following,
The common factors would be: =>
(this is common in both polynomials, so we would take just one of them as a factor.
and,
Their product =
