write and solve an equation to find the difference between the location of point a and point b on the ruler.

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.

If two shapes can be mapped onto one another using rigid transformations, then yes, they can be said to be congruent.The preimage of right angle triangle and a right angle triangle are the example of congruent shapes.

Two shapes are considered to be congruent if they can be mapped onto one another using rigid transformations (a sequence of one or more rotations, translations, and reflections). A congruent triangle is produced by any series of rigid transformations applied to a triangle.

Now, let's learn about Rigid transformation

A rigid transformation of the plane, also known as an isometry, keeps length intact. "Rigid transformations" include reflections, translations, rotations, and combinations of these three transformations.

Step-by-step explanation:

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

Step-by-step explanation:

You already know that TS = AB and TU = BC because it shows that in the images using the tick marks. 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. The only two side lengths not equal to each other yet are US and CA so if those were to be equal to each other, all corresponding side lengths would be equal to each other.

Answer:

Step-by-step explanation:

yes proper subset  is different from a regular subset. The empty set is a proper subset of every set except for the empty set

A proper subset of a set A is a subset of A that cannot be equal to A. In other words, if B is a proper subset of A, then all elements of B are in A but A contains at least one element that is not in B.

Subset: If A and B are sets and every element of A is also an element of B, then:

A is a subset of B, denoted by A ⊆ B.

or equivalently, B is a superset of A, denoted by B ⊇ A.

Any set is considered to be a subset of itself. No set is a proper subset of itself. The empty set is a subset of every set. The empty set is a proper subset of every set except for the empty set.

For example, A = {1, 2, 3, 4, 5} and B = {1, 2, 3, 4, 5, 6, 7, 8, 9, 10}.

A = {1, 2, 3} and B = {1, 2, 3}

Here, A is a subset of B, or we can say that B is the superset of A.

Proper Subset: If A is a subset of B, but A is not equal to B (that is, there exists at least one element of B which is not an element of A), then

A is also a proper (or strict) subset of B; this is written as A ⊊ B.

For example A = {1, 2, 3} and B = {1, 2, 3, 4}.

Clearly, A is not equal to B and element {4} belongs to set B but is absent in set A, so we have one element in set B which is not an element of set A. Thus, A can be called a proper subset of B.

Hence, a proper subset of a set A is a subset of A that is not equal to A. In other words, if B is a proper subset of A, then all elements of B are in A but A contains at least one element that is not in B, thus the proper subset may or may not be the same.

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.

Using proportions, it is found that they traveled a total of 3066 miles around the lake.

A proportion is a fraction of a total amount, and equations can be built to find the desired measures in the problem using a rule of three, that can be either direct(cross multiplication) or inverse(line multiplication), deriving from proportional relationships.

One example of application of proportions is for unit rate problems, in which we find the unit rate for a single person, and then the total amount for a number n of people is given by n multiplied by the unit rate.

For this problem, we have that:

Hence the total distance traveled by all these people is given as follows:

The expression [tex]-2\vec C+6\vec D[/tex] in the ordered pair notation is (16,-16).

The vector components of a vector are represented as the ordered pair of its x and y components.

For example, if a vector has x - component 'a' and y- component 'b' , then the ordered pair notation for the vector is (a, b), where the vector is [tex]a \vec i+b \vec j[/tex].

Now the vector C has its x- component = -2

y- component of C = -1

Therefore, ordered pair notation of C = (-2, -1)

x- component of D = 2

y-component of D = -3

Therefore, ordered pair notation of D = (2,-3)

So the expression  [tex]-2\vec C+6\vec D[/tex] = -2 (-2,-1) +6 (2,-3) = (4,2) + (12, -18)

= (16, -16)  in the ordered pair notation.

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.
