Answer: 15x-30
Step-by-step explanation:
This is a composite function, which means you are combining two functions together. This can seem tricky, but once you understand how to break these problems into pieces it becomes much easier.
g(f(x)) can be read as g of f of x. Which means we are plugging the function f(x) into the function g(x). Think of it like this, if I were to ask you to find g(3) you would need to plug the value 3 into the function g(x). This would look like this: g(3) = 5(3) So g(3)= 15
However, when we are working with a composite function instead of a whole number we want to first look at the second function, so that we can rewrite the problem. In this problem f(x) = 3x -6
So, I can rewrite this as g(3x -6)
- Now, all you have to do is plug this function into g (x) just like I plugged in the value of 3 above. This will look like this:
g(3x-6) = 5(3x-6)
- Then, you just need to multiply each term by 5, following the distributive property:
g(3x-6) = 15x - 30
Answer:
Area = 40x + 15 squared units.
Step-by-step explanation:
Area of a rectangle = Length × width
The original 15 people are 10% of the total number of people who received the mail.
Step-by-step explanation:
Given,
Number of people who received mail = 15
Mail further sent to 3 more friends;
Number of people who received mail from 15 people = 15*3 = 45 people
Number of people who received mail from 45 people = 45*2 = 90 people
Total number of people = 15+45+90 = 150 people
Now,
Percent of original people = 
Percent of original people = 
The original 15 people are 10% of the total number of people who received the mail.

45 - 7 = 38
unknown quantity is the miles already traveled.
The formula for the slope of a line between two points is m=y2-y1/x2-x1. Substitute the given coordinates into this equation and solve:
m=(48-12)/(32-34)=36/-2= -18
The slope is -18
