C(x) = 4x³+7x²-14x-6
Step-by-step explanation:
Given that the amount of water used in normal days is given by the equation;
W(x) = 5x³ +9x²-14x +9 -----(i)
The amount of decrease in water used is modeled by the equation;
D(x)= x³+2x² +15--------(ii)
To get the function C(x) that models the water used by the car wash on shorter day you subtract equation (ii) from equation(i)
5x³ +9x²-14x +9
- x³+2x² +15
-------------------------
4x³+7x²-14x-6

Answer:
option F
Step-by-step explanation:
The line that slopes backwards, has an x-intercept at 9 and y-intercept at 4.
The equation is given by:
This implies that:
The line that slopes forward has a y-intercept of -2 and a slope of 3
The equation is given by:
or in standard form:
The correct choice is F
Answer:
8
Step-by-step explanation:
You have to list the numbers in the correct order then fond the one that falls in the middle, if there are 2 numbers that fall in the middle, then you add those 2 then divide by 2.

Answer:
To find the volume of this cube, you would have to multiply 1.08 by 5.25 by 3.3 feet. If you did this, you would get: 18.711 feet^3. This is the volume of the rectangular prism.
Hope this helped!
It is -8y+12
You have to multiply 4 by -2 which equals -8
Then you do 4x3 which equals 12
