The entire family (5 people) save 120 gallons per day.

Subtraction:

Subtraction means we have to find the difference of the numbers.

Given,

A family of five recently replaced its 5-gallon-per-minute showerheads with water-saving 2-gallon per minute showerheads.

Each member of the family averages 8 minutes in the shower per day.

Here we need to find the entire family savings per day.

According to the question,

The total bath time for the whole family is,

=> 8 x 5 = 40

So for one day,

If the showerheads cost 5 gallon per minute, then the cost for the family is,

=> 40 x 5 = 200

If the showerheads cost 2 gallon per minute, then the cost for the family is,

=> 40 x 2 = 80

So, the savings is,

=> 200 - 80

=> 120

So, they save 120 gallons per day.

To find the x-intercept of any equation, set the y-value to 0.

Step-by-step explanation:

Example:

y=1x+4

To find x-intercept:

0=1x+4

1. Subtract 4 from both sides

2. Divide both sides by 1

The x-intercept is -4

Answer:

837x4=3348

Step-by-step explanation:

First multiply 7 by 4 which is 28. You keep the 8 as part of your answer, and put 2 above 3 in other words regroup.

Next multiply 3 by 4 which is 12 and add 2 which equals 14. Again, leave the 4 as part of your answer and put the 1 over the 3 in other words regroup.

Then multiply 8 by 3 and add 1 which equals 33.

Step-by-step explanation:

Your hourly wage is divided by the number of hours worked in a week to determine straight-time pay. :- False

The entire set amount of money provided to an employee over a specific time period—typically a year—is referred to as a salary. The amount paid to an employee for each hour of work is known as their hourly wage in comparison.

Let's assume the straight time pay to be x.

Let the hourly pay rate be y

If a person has worked N no. of hours in a week.

Then the straight-time pay will be the product of the hourly pay rate and the number of hours the person worked.

Therefore,

The straight time pay, x = N × y = Ny

Hence, the statement " the formula for figuring straight time pay is your hourly rate divided by the number of hours worked in a week" is false.

The type of function of the given graph is polynomial in nature.

Each element of X receives exactly one element of Y when a function from one set to the other is used.

A)  The given function is a polynomial of the third degree.

B)  The factored form of the polynomial is: [tex]-\frac{1}{1500} (x+20)(x+5)(x-15)[/tex]

The standard form is: [tex]p(x)=-\frac{x^3}{1500} -\frac{x^2}{150} +\frac{11x}{60} +1[/tex]

C)  The zeroes of the polynomial function are -20, -5 and 15

D)  The linear factors are (x+20)(x+5) and (x-15)

E)   The equation of the function is  [tex]y=-\frac{1}{1500} (x+20)(x+5)(x-15)[/tex]

F)   From the graph it is seen that the factors of the polynomial function are (x+20)(x+5) and (x-15).

Now at x=0, y=1.

Substituting these values we get:

1=a(0+20)(0+5)(0-15)

or, a =  [tex]-\frac{1}{1500}[/tex]

So the value of a for the equation is [tex]-\frac{1}{1500}[/tex] .

G)   The equation for the function in the graph is

[tex]y=-\frac{1}{1500} (x+20)(x+5)(x-15)[/tex]
