Answer:
Option C. x + 12 ≤ 2(x – 3)
Step-by-step explanation:
From the question, we obtained the following information:
x + 12 ≤ 5 – y .......(1)
5 – y ≤ 2(x – 3) ....... (2)
To know which option is correct, do the following:
From equation 2,
5 – y ≤ 2(x – 3)
Thus, we can say
5 – y = 2(x – 3)
Now, we shall substitute the value of 5 – y into equation 1 as shown below:
x + 12 ≤ 5 – y
5 – y = 2(x – 3)
x + 12 ≤ 2(x – 3)
From the above illustration, we can see that if x + 12 ≤ 5 – y and 5 – y ≤ 2(x – 3), then x + 12 ≤ 2(x – 3) must be true.
Option C gives the correct answer.
Answer:
Step-by-step explanation:
Given
Required
Determine the equation
First, we calculate the intercepts using:
Where
b = Intercept on y axis.
a = Intercept on x axis.
From the question:
The equation becomes:
Multiply through by 3b
We have:
So:
Make b the subject
Substitute in to get the equation
Make 3y the subject
Make y the subject
