Answer:

x = 58, y = 61

Step-by-step explanation:

We can use two properties of a parallelogram to solve this

1. The opposite angles of a parallelogram are equal

2. The sum of the 4 interior angles of a parallelogram equal 360

Using property 1,

Using property 2
(2x - 3) + y + (y + x) + y = 360

3x + 3y + 3 = 360

3x + 3y = 360 - 3 = 357

Divide both sides by 3 to get
x + y = 357/3
x + y = 119  [2]

Add [1] and [2] together to eliminate y and get

x - y + x + y = -3 + 119

2x = 116

x = 116/2 = 58

Use equation [2]

x + y = 119
58 + y = 119

y = 119 - 58

y = 61

Answer: D; 360

Step-by-step explanation: To find percentages, I like to set up proportional relationships to find the amount. It would look like this:

[tex]\frac{90}{100}[/tex] = [tex]\frac{?}{400}[/tex]

90=  part %

100= whole %

?= amount of the %

400= all of the item(s)

So, we would cross multiply the 90 and the 400, then divide it by 100. That would be 36,000. So, that divided by 100 leaves us with 360. I hope this helped!

Observing the provided equation, We can't solve these equations using substitution method or any other methods because these lines are parallel and never intersect each other.

The definition of an equation in algebra is a mathematical statement that demonstrates the equality of two mathematical expressions.

The algebraic approach to solving simultaneous linear equations is known as substitution method. The value of one variable from one equation is substituted in the second equation in this procedure, as the name implies.

x=4-8y

3x+24=12

Taking first equation and rearranging it we get,

Answer:

  a. 31 months

  b. $818.32

  c. $168.32 interest

Step-by-step explanation:

Given that Joe makes a minimum payment of $21.45 on his credit card purchase of $650 with an APR of 19.85%, you want to know ...

If the balance is reduced by $21.45 per month, it will take ...

  $650/($21.45/mo) ≈ 30.3 months

to pay off the balance.

Joe will be making payments for 31 months.

The total amount Joe pays for his sound system is the sum of its initial cost and the total of interest payments. That sum is ...

  cost + interest = total paid

  $650 +168.32 = $818.32

Joe will pay a total of $818.32.

The total amount of interest Joe pays is $168.32.

__

Additional comment

If the total payment each month is $21.45, then it will take 43 months to pay off the system, for a total cost of $909.61, of which $259.61 is the cost of the credit. (The finance charge is paid first from this payment amount, so the amount that goes to reduce the balance is less.)

The average grade received on two tests and the final exam is 78.67%

What is average?

The ratio of the sum of the values in a particular set to all the values in the set is the mean value, which is the definition of the average.

The average formula has numerous practical uses. If we were asked to determine the average male height in India or the average age of the men and women in a group, we would add up all the data and divide it by the total number of data points.

Given, the grades in tests are 74% and 82%. Also, the grade on final exam is 80%.

Now, considering that we have to find the average grade in tests and final exams combined, we put the average formula.

Average grade = Sum of percentages of each exam/Total exams

Thus, average is

The supplement of BIE equals the supplement of GMD is a false assertion if lines BG and CF are parallel.

Angles with a supplementary sum are those whose sum is 180 degrees. For instance, the total of angle 130° and angle 50° is 180°, hence they are supplementary angles.

Lines BG and CF are parallel, as shown in the figure.

If BIE = X, then its supplement of BIE will be 180 - X;

similarly, if GMD = Y, then its supplement of GMD will be 180 - Y.

Since BG and CF are parallel, the supplements of BIE and GMD are interior angles on the same side ( as shown in figure)

and for parallel line the interior angle on the same side is 180

The correct option that describes the vertical asymptote is; B: There is a vertical asymptote at x = 4 because Limit of g (x) as x approaches 4 minus = infinity and limit of g (x) as x approaches 4 plus = infinity

A vertical asymptote of a graph is defined as a vertical line x = a where the graph tends toward positive or negative infinity as the inputs approach a.

A vertical asymptote is a value of x for which the function is not defined, that is, it is a point which is outside the domain of a function;

In a graph, these vertical asymptotes are given by dashed vertical lines.

An example is a value of x for which the denominator of the function is 0, and the function approaches infinity for these values of x.

We are given the function;

g(x) = 2(x + 4)²/(x² - 16)

Simplifying the denominator gives;

(x² - 16) = (x + 4)(x - 4)

Thus, our function is;

g(x) = 2(x + 4)²/[(x + 4)(x - 4)]

(x + 4 ) will cancel out to give;

g(x) = 2(x + 4)/(x - 4)

Answer:

I was willing to pay $20 more for the toy than I actually paid.

Step-by-step explanation:

Let us take the maximum bid be y

So,

(y × 60) ÷ 100 = 30

60y/100 = 30

60y/100 × 100 = 30 × 100

60y = 3000

60y/60 = 3000/60

y = 50

60% of $50 is $30

The matrix equation Ax=b with one unique solution says that column A is linearly independent.

Two vectors are linearly dependent if at least one of them can be expressed as a linear combination of the others. If no vector can be expressed as a linear combination of the others, then two or more vectors are said to be linearly independent.

Given the matrix equation is Ax=b. And this equation has one unique solution. Then, let us assume this unique solution is x₁.  Let the column values of A be A₁, A₂, A₃, .... Aₙ.

If there is only one solution to the equation Ax = b for all b, then assume b = 0 and come to the conclusion that there is only one solution to the equation Ax = 0 as well. Consequently, the only solution is straightforward, and the columns of A are linearly independent.

For instance, a matrix contains two rows and three columns. a group of integers organized in a rectangular array in rows and columns. Matrix elements or entries refer to numbers. In several disciplines of engineering, physics, economics, statistics, and mathematics, matrices have a wide range of applications.

The eigenvalues and eigenvectors of the sum of two matrices are typically not the same as the sums of the eigenvalues and eigenvectors of the individual matrices. In actuality, there is no way to separate the eigenvalues of A and B from one another.

When a vector v is an eigenvector of both A and B, it is also an eigenvector of A+B, with an eigenvalue equal to the sum of its eigenvalues for A and B, respectively. There is, however, no reason to anticipate that two matrices will share an eigenvector in general. There is no method to create an eigenvector of A+B from two random eigenvectors of A and B alone.

When the matrices A and B commute, or when they fulfill AB=BA, this is a significant exception. In this situation, their invariant spaces coincide, and if both of them are diagonalizable, they are concurrently diagonalizable, which means that their eigenvectors do as well. As was already noted, in this specific instance, the eigenvectors of A+B are likewise the same.
