Answer:

-78x² - 4x^-7 + 7

Step-by-step explanation:

we compute using mathematical rules

-2x^2- 2x^-7 -2x^2-2x^-7 - (2x^2 +72x^2+7)

-4x^2-4x^-7-2x^2-72x^2-7

= -78x² - 4x^-7 + 7

The subtraction of the polynomial - 2x² - 2x - 7 from 2x² + 7 will be 4x² + 2x + 14.

Algebra is the study of abstract symbols, while logic is the manipulation of all those ideas.

The definition of simplicity is making something simpler to achieve or grasp while also making it a little less difficult.

The expressions are given below.

- 2x² - 2x - 7 and 2x² + 7

Subtract - 2x² - 2x - 7 from 2x² + 7, then we have

⇒ (2x² + 7) - (- 2x² - 2x - 7)

⇒ 2x² + 7 + 2x² + 2x + 7

⇒ 4x² + 2x + 14

The subtraction of the polynomial - 2x² - 2x - 7 from 2x² + 7 will be 4x² + 2x + 14.

First, you should list all the factors of 44 and 22. For 44, the factors are: 1, 2, 4, 11, 22 and 44

For 22, the factors are: 1, 2, 11 and 22

The greatest common factor is 22.

Answer: 22

Step-by-step explanation:

In order to find GCF of 44 and 22, take the prime factorization of the two numbers

22: 11*2

44: 11*4=11*2*2

Notice they both have 11*2 in their prime factorization.

11*2=22

GCF of 44 and 22 is 22

The rational number equivalent to 1.28 bar over 28 is 1and 28 over 99 that is option 2) is correct

The number that we have been given is  1.28 bar over 28 that is 28 is repeating.

Now we have to convert it into simple fraction.

For we will first denote,

                  X = 1.28 bar over 28

Multiplying both side by 100 as two digits are being repeated we get,

                   100X = 128.2828…

               Now subtracting it from X on both side s and putting the value of X we get

        100X – X = 128.28… - 1.2828….

           99X = 127

              X =127/99

              X = 1 28/99

Hence the rational number equivalent to 1.28 bar over 28 is 1and 28 over 99 that is option 2) is correct

Using the addition of all the exercise, Javier runs on the treadmill on Monday is 0.40 hours.

Addition is one of the mathematical operations. The addition of two numbers results in the total amount of the combined value.

Given that Javier completed 3 repetitions of each exercise. thus by multiplication time taken by Javier to complete each exercise is as follows;

Squats = 0.8 x 3= 0.24 hour

Crunches = 0.03 x 3 = 0.09 hour

Lunges = 0.04 x 3 = 0.12 hour

curls = 0.05 x 3 = 0.15 hour

we can calculate the total time taken to complete all exercises as;

0.24 + 0.09 + 0.12 + 0.15

= 0.60 hour

Now the time took on treadmill by Javier;

1 hour - 0.60 hour

0.40 hour

Hence,  If he completed 3 repetitions of each exercise, then he run 0.40 hours on the treadmill on Monday.

The y-intercept is a value that represents the point on a chart where the line intersects with the y-axis. In the above chart, the y-intercept is 5 dollars.

The purpose of the y-intercept is to tell us the initial cost of renting the boat in this instance, before the boat has been used for any number of hours. This is because at the y-intercept, x would be 0 which means that the number of hours would be zero.

SSS Triangle Congruence Postulate is when two triangles are congruent to each other because all the corresponding side lengths are equal to each other. So we already have two side lengths that are equal to each other, and, in order for SSS to be true, we need all 3 side lengths to be equal to each other.

It is given that there are 8 fluid ounces in 1 cup.

We have to check does the amount of cups gets doubled  , if we double the amount of fluid ounces.

What do you mean by unitary methods ?

The unitary method is a method for solving a problem by the first value of a single unit and then finding the value by multiplying the single value.

As per the question ;

In 1 cup , no. of fluid ounces = 8

So ;

If we double , the no. of fluid ounces , i.e.,

Answer:

I would say it would be a translation transformation.

Step-by-step explanation:

Why would I say it would translation? Well, for starters; translation is the only one that would make sense (though, reflection could be the second best answer; but not the correct answer [explanation later]). Dilation doesn't make sense because it's not scaling from either bigger to smaller; from the picture. Translation makes sense because it goes from a different location, keeping its original state. As I said at the beginning, reflection could be the second best answer if it weren't for its mirroring action (it's reversed); making it not an available option for this question. Lastly, rotation definitely could not be correct because it's not rotating at all.

Therefore, translation would be the most viable option in this question.

B 55x + 65 = 296; x = 4.2 hours

Step-by-step explanation:

The equation to determine the number of hours worked by the plumber is 65 + 55x = 296.

The number of hours worked by the plumber is 4.2

Option B is the correct answer.

An equation is a mathematical statement that is made up of two expressions connected by an equal sign.

We have,

Charges for home visit = $65

Charges for each hour = $55

Let the number of hours = x

Total charges = $296

We can make an equation:

65 + 55x = 296

The number of hours can be calculated.

65 + 55x = 296

Subtracting 65 on both sides.

65 + 55x - 65 = 296 - 65

55x = 231

Dividing both sides by 55.

x = 231 / 55

x = 4.2

Thus,

The equation to determine the number of hours worked by the plumber is 65 + 55x = 296.

The number of hours worked by the plumber is 4.2

Option B is the correct answer.
