Answer:
Who?
Step-by-step explanation:
The equation in the function form is f(x) = -3x + 15 and the tub started with 15 gallons of water.
<h3>What is a function?</h3>
It is defined as a special type of relationship, and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.
We have an equation:
y –12 = –3(x – 1)
We can write the above equation as follows:
y = 12 - 3(x - 1)
y = 12 - 3x + 3
y = -3x + 15
or
f(x) = -3x + 15
Plug x = 0
f(0) = 15
The tub started with 15 gallons of water.
Thus, the equation in the function form is f(x) = -3x + 15 and the tub started with 15 gallons of water.

Answer:
x < -4
Step-by-step explanation:
Hello!
I don't see the drop-down menus, but I will try to help as best as I can...
Like any other equation, you are trying to get x by itself.
Our first step will be to subtract 13 from both sides.
-7x + 13 > 41
-7x > 28
Now, we will need to divide -7 from both sides. But, remember, dividing or multiplying a negative number will switch, or flip, the sign.
-7x/-7 > 28/-7
Doing the above equation will provide us with x all alone on one side:
x < -4
Hope I helped!

Answer:
36 feet
Step-by-step explanation:
3ft is 1 yard so you would multiply the 12 yards by 3 making 36.
Answer:
$2942.27
Step-by-step explanation:
Given the circumference of a circle, we can get the radius which will then help us get the area and finally estimate the cost of tiling.
C=2πr
Where C is circumference and r is radius
Making r the subject of the formula then
r=C/2π
Substituting 157 ft for C then
r=157/2π=24.9873260654276 ft
Area, A is given by A=πr²
A=π*(24.9873260654276)²=1961.50509613606
Rounded off, the area is 1961.51 ft²
Given the cost per unit square foot as $1.5 then the overall cost will be
$1.5*1961.51=$2,942.265
Rounded off as $2942.27
