The correct answer is ( -2.2, -3).

We occasionally discover the value of an unknown variable while solving the system of equations. We can display the graph using the equation, but if the graph and the equation are parallel, we will not be able to solve the system of equations.

We have a condition that, if applied, allows us to determine how many solutions this equation has: if it has one solution, no solutions, or infinitely many solutions.

y = -3 _____(1)

y = x-0.8 _____(2)

to substitute the value of y in the equation in 2

-3 = x - 0.8

-3 + 0.8 =x

-2.2 = x

Thus the correct answer is  ( -2.2, -3).

The simplified form of 1 and 3 over 4 times, 2 and 2 over 3 is 4/3.

Given,

1 and 3 over 4 times

2 and 2 over 3 times

We can convert this to mathematical form:

That is,

1 and 3 over 4 times = (1 + 3) / 4

2 and 2 over 3 times = (2 + 2) / 3

Now, equate the above terms:

We get,

(1 + 3) / 4 x (2 + 2) / 3

= (4 / 4) x (4 / 3)

= 1 x (4 / 3)

= 4 / 3

Making t the subject of formula gives the following expression: t = (2 - 3q)/(q + 4).

An expression can be defined as a mathematical equation which is used to show the relationship existing between two or more variables and numerical quantities.

In this exercise, you're required to describe the steps that should be taken to make t the subject of formula. Therefore, the appropriate and required steps are listed as follows:

q = (2 - 4t)/(t + 3)

Cross-multiplying, we have:

q(t + 3) = (2 - 4t)

qt + 3q = 2 - 4t

Collecting like terms, we have:

qt + 4t = 2 - 3q

Factorizing t, we have:

t(q + 4) = 2 - 3q

Dividing by (q + 4), we have:

t = (2 - 3q)/(q + 4)

The answer to the question is c 47,625

The concept used is geometric progression.

A geometric progression is a sequence in which any element after the first is obtained by multiplying the preceding element by a constant called the common ratio which is denoted by r.

Here we can see that shares are being halved per week

we can say that the value of r is 1/2

so we can use the formula of sum of geometric progression to calculate the total number of shares.

sum of geometric progression formula =a(1-r∧n)/1-r

Here we can see that the value of n is 7

On putting the values in the formula we get

sum=24,000(1-1/128)/(1/2)

On further solving we get-

24000×127×2/128 which is equal to 47,625

Hence the total no of shares  of the company he bought are 47,625

Answer:

Step-by-step explanation:

In this problem, we need to arrange 150 chairs in rows for a school play. You want each row to have the same number of chairs.

We can find the prime factorization of 150 as follows :

150 = 2, 3, 5, 5

150 is not a perfect square. 144 is a perfect square and 12² = 144. So, there are 12 possible arrangements.

After solving the given equation 25²x=144, the value of x = 144/625.

So,

Then,

Therefore, after solving the given equation 25²x=144, the value of x = 144/625.

The solutions to the proportional equation are given as follows:

x = -4 and x = 5.

A proportion is a fraction of a total amount, and equations can be built to find the desired measures in the context of the problem using operations such as multiplication or division.

One example of application of proportions is for the solution of equations when two sides are proportional, meaning that multiplication operations are applied between the opposite sides to find the unknown variable.

For this problem, we already are given the following proportional equation:

3x/5 = 12/(x + 1).

Due to the equality sign, we can apply cross multiplication, hence:

3x(x + 1) = 60

3x² + 3x = 60

3x² - 3x - 60 = 0

x² - x - 20 = 0

(x - 5)(x + 4) = 0.

Hence the solutions are found as follows:

Answer:

(-4, 0) U (1, ∞)

Step-by-step explanation:

Set each factor EQUAL to zero to find the zeroes (since it is not actually equal to zero, you will use an open circle when graphing and an open bracket when writing in interval notation).

x = 0           x-1 = 0             x + 4 = 0

                  x = 1                x = -4

Next, choose a value to the far left, between each of the zeroes, and to the far right to evaluate if it makes a true statement when input into the given inequality.

far left (I choose -5): -5(-5 - 1)(-5 + 4) > 0   →  (-)(-)(-) > 0  →   negative > 0  FALSE

- 4 to 0 (I choose -2): -2(-2 - 1)(-2 + 4) > 0   →  (-)(-)(+) > 0  →   positive > 0  TRUE

0 to 1 (I choose 0.5): .5(.5 - 1)(.5 + 4) > 0   →  (+)(-)(+) > 0  →   negative > 0  FALSE

far right (I choose 2): 2(2 - 1)(2 + 4) > 0   →  (+)(+)(+) > 0  →   positive > 0  TRUE

Point A' after the dilation of the scale factor by 1/3 is (-1,2) is the correct option.

The given point is;

Point A = (3, -6), scale factor = 1/3

Fortunately, because the dilation is centered at the origin (0,0), we can multiply the scale factor by the x and y-coordinates to acquire the image point coordinates.

Point A' = (3×1/3, -6×1/3)

Point A' = (1, - 2)

As a result, if it grows larger, it should start moving away from the origin, while if it grows smaller (as it does here), this should move closer to a origin.
