The total number of hours taken by n students is modeled by .
<u>Step-by-step explanation:</u>
Here we have , Suppose the number of hours boys B and the number of hours girls G take to complete their homework is modeled by B=2n+5 and G=3n-1, where n is the number of students. We need to write a function that models the total number T of hours it takes boys and girls to complete their homework for n students .
- The number of hours boys take to complete their homework, B=2n + 5
- The number of hours girls take to complete their homework, G = 3n – 1
We are to derive the total number T of hours taken by n students.
Total number of Hours
T=Number of hours taken by boys+Number of hours taken by Girls
T=B+G
⇒
Next, we simplify by collecting like terms
⇒
⇒
⇒
The total number of hours taken by n students is modeled by .
If your trying to find x, distribute 2(x+6), which is by multiplying 2 times x, which is 2x and 2 times 6, which is 12. So your left off with 4x+2=2x+12. In order to find x, we have to move the 2 to the right, which will give us 2x+10 and then move 2x to the left to give us 2x=10. Divide both sides by 2, and x= 5.

Answer:
The y-intercept is 0
Step-by-step explanation:
Here, we want to get the y-intercept value of y = sin x
From the plot of the graph, we can see that the graph of sin x touches the y-axis at the point y = 0
So therefore, the y-intercept of y = sin x is 0
