Answer:
21x - 42, see below :)
Step-by-step explanation:
Hello!
We know that f(x) is equal to 3x - 6
We want to know what 7 * f(x) is so we should first substitute f(x) for 3x - 6
7 * f(x)
7(3x-6)
We use distributive property to open the parenthesis:
7 * 3x + 7 * -6
21x - 42
Answer:
The slope of the equation is -3.
Step-by-step explanation:
Given : Mr. Mole's burrow lies 5 meters below the ground. He started digging his way deeper into the ground, descending 3 meters each minute.
To find : What is the slope ?
Solution :
Let x be the number of minutes taken to dig the ground.
He started digging his way deeper into the ground, descending 3 meters each minute i.e. '-3x'
Let y is the total distance travel to dig the ground.
Mr. Mole's burrow lies 5 meters below the ground.
The equation form is 
Comparing with general slope form i.e.
where m is the slope.
The slope of the equation is -3.
Answer:
12 feet
Step-by-step explanation:
Given: length = 15 feet, width = L x 80%
Unknown: width = ?
width = L x 80%
w = (15ft) x 80% or (15ft) x .80
w = 12 ft
