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.

Answer:

He did an error because he multiplied equation 2 wrongly.

The correct multiplication should have been:

-6x + 9y = 6        Multiply equation by 2 by 3

Step-by-step explanation:

Given the system of equations

3x-5y=4

-2x+3y=2

This is what student solved

6x - 10y = 8        Multiply equation 1 by 2

-6x + 3y = 6        Multiply equation by 2 by 3

_________

       -7y = 14

          y = -2

He did an error because he multiplied the equation 2 wrongly.

The correct multiplication should have been:

-6x + 9y = 6        Multiply equation by 2 by 3

NOW, HERE IS THE CORRECT VERSION

6x - 10y = 8        Multiply equation 1 by 2

-6x + 6y = 6        Multiply equation by 2 by 3

_________

       -4y = 14

          y = -2/7

Answer:

Step-by-step explanation:

x²-9x -36 =(x+3) (x -12)

because

x² -12x +3x -36 =

x( x-12) +3( x-12)=

(x-12) (x+3)

Answer:

12x=50×50−38×38

12x=50²−38²

20x=(50+38)(50-38)

12x=88*12

x=88

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.

We will need to use the substitution method to solve the question. The difference between the two numbers is 11.5

Substitution method is used to solve a system of equations. First the equation is solved for one variable and then the value is used in the other equation to solve for the other unknown variable. In this question we have been told the sum of two numbers is 32. Let us take the two numbers as x and y. Then we can say that

x+y=32 ...(i)

Next we know that when 5 is subtracted from 4 times one number the result is 8 times the other number, we can write it as

4x-5=8y

4x-8y=5....(ii)

So we have two equations

x+y=32

4x-8y=5

We will multiply equation (i) by 4 to cancel out x and solve for y

4x+4y=128

4x-8y=5

(-)  (+)   (-)

-----------------

    12y=123

y=10.25

We substitute the value of y in equation (i)

x+y=32

x+10.25=32

x=32-10.25=21.75

We need to find the difference between two number which is x-y=21.75-10.25=11.5

Therefore we found out by substitution method that the difference between the two numbers is 11.5

Answer:

x=17

Step-by-step explanation:

1: Simplify both sides of the equation.

8x−9+53=180

8x+−9+53=180

(8x)+(−9+53)=180(Combine Like Terms)

8x+44=180

8x+44=180

2: Subtract 44 from both sides.

8x+44−44=180−44

8x=136

3: Divide both sides by 8.

(8x=136 )/8

x=17

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]
