Mrs. Rodger got a weekly raise of ₫145. If she gets paid every other week, write an integer describing how the raise will affect her paycheck.
Let the 1st paycheck be x (integer).
Mrs. Rodger got a weekly raise of ₫ 145.
So after completing the 1st week she will get ₫ (x+145).
Similarly after completing the 2nd week she will get ₫ (x + 145) + ₫ 145.
=\( ₫ (x + 145 + 145)\)
= \(₫ (x + 290)\)
So in this way end of every week her salary will increase by ₫ 145.
if a is an n × n matrix, how are the determinants det a and det(5a) related? Remark: det(5A) = 5 det A only in the trivial case of 1 Times 1 matrices How are the determinants det A and det B related if A = a1 a2 a3
b1 b2 b3 c1 c2 c3), B = 2a1 3a2 5a3 2b1 3b2 5b3 2c1 3c2 5c3;
The determinants det a and det(5a) are related by a scalar multiplication of 5^n, where n is the dimension of the matrix a. In other words, det(5a) = (5^n) det a. This is because multiplying a matrix by a scalar multiplies its determinant by the same scalar raised to the power of the matrix's dimension.
For the second part of the question, the determinants det A and det B are related by det B = (2*3*5) det A = 30 det A. This is because multiplying a row of a matrix by a scalar multiplies its determinant by the same scalar, and multiplying a matrix by a scalar multiplies its determinant by the same scalar raised to the power of the matrix's dimension.
The determinant of a matrix represents the scaling factor of the matrix's transformation on the area or volume of the space it is operating on. Scalar multiplication of a matrix by a scalar s multiplies its determinant by s^n, where n is the dimension of the matrix. This is because the determinant is a linear function of its rows (or columns), and multiplying a row (or column) by a scalar multiplies the determinant by the same scalar.
For the second part of the question, we can use the fact that the determinant of a matrix is unchanged under elementary row operations, and that multiplying a row of a matrix by a scalar multiplies its determinant by the same scalar. We can therefore multiply the first row of A by 2, the second row by 3, and the third row by 5 to obtain B. This multiplies the determinant of A by the product of the three scalars, which is 2*3*5 = 30.
In summary, the determinants of a matrix and its scalar multiple are related by a power of the scalar equal to the dimension of the matrix. Additionally, the determinant of a matrix is multiplied by the product of the scalars used to multiply each row (or column) of the matrix when performing elementary row operations.

How would I solve the equation below:
\(f(x)=2x-7\)
\(Solve: f(x^{2})=x-1\)
Answer:
x = -1.5, +2.0
Step-by-step explanation:
You want to solve the equation f(x²) = x-1, given that f(x) = 2x -7.
SolutionFirst, we find the meaning of f(x²) by putting x² into the function definition where x is:
f(x²) = 2(x²) -7
Then, we set that equal to x-1 and solve the resulting quadratic.
2x² -7 = x -1
2x² -x -6 = 0 . . . . . . . subtract (x-1)
(2x +3)(x -2) = 0 . . . . factor
The solutions to this are the x-values that make the factors zero:
2x +3 = 0 ⇒ x = -3/2
x -2 = 0 ⇒ x = 2
The solutions are x = -3/2 and x = 2.
__
Additional comment
The attached graph solves the equation we get when we subtract (x-1) from both sides of what you're trying to solve. The solutions are the x-intercepts of the graph.
The factoring can be done by splitting the x-term into two parts. Their product is the product of the first and last terms.
2x² -x -6 = 0
2x² -4x +3x -6 = 0 . . . . . 2·(-6) = -12 = (-4)(3) and -4+3=-1, the x-coefficient
2x(x -2) +3(x -2) = 0 . . . . factor each pair of terms

The circle x^2+y^2-2x-8y+17=0 has translated 5 units to the leftand 2units down.
Step-by-step explanation:
If we translate this circle to the left 5 units, and 2 units down,
we will subtract 5 from the center x coordinate and 2 for the center y coordinate
The center is (1,-4)
So the new center prime is (-4,-6)
Since a translation keep angles and measures,
Our radius will remain untouched so our new equation is

does a Powerade cost?
The cost of a Powerade is $0.75 if 2 bags of chips and 2 Powerades cost $3.50 and one bag of chips and 3 Powerades cost $3.75.
Let the cost of one Powerade be x
The cost of one bag of chips be y
Cost of 2 bags of chips and 2 Powerades = $3.50
Cost of 2 bags of chips = 2y
Cost of 2 Powerades = 2x
2x + 2y = 3.50 ----(i)
Cost of one bag of chips and 3 Powerades= $3.75
Cost of 1 bag of chips = y
Cost of 3 Powerades = 3x
x + 3y = 3.75
Multiply the above equation by 2
2x + 6y = 7.50 -----(ii)
Subtract (ii) and (i)

Find an expression to present the perimeter of the rectangle below
An expression to represent the perimeter of the rectangle with 10/(x² + 11x +24) and (x+1)/(x+3) would be (x+12)(x+6)//(x+8)/(x+3).
What is the perimeter?
A closed path that covers, encircles, or outlines a one-dimensional length or a two-dimensional shape is called a perimeter. A circle's or an ellipse's circumference is referred to as its perimeter. There are numerous uses in real life for perimeter calculations.
Here, we have
Given: Sides = 10/(x² + 11x +24) and (x+1)/(x+3)
The perimeter is when you add all the sides of a shape.
In a rectangle, two sides are the same, and so are the other two. therefore, if the two sides are 10/(x² + 11x +24) and (x+1)/(x+3) the expression will be:
= 2(10/(x² + 11x +24)) + 2(x+1)/(x+3)
= 20/(x² + 11x +24) + 2(x+1)/(x+3)
= 20/(x+8)/(x+3) + 2(x+1)/(x+3)
= {20 + 2(x+1)(x+8)}/(x+8)/(x+3)
= {20 + 2(x² + 9x + 8)}/(x+8)/(x+3)
= { 20 + 2x² + 18x + 16}/(x+8)/(x+3)
= {2x² + 18x + 36}/(x+8)/(x+3)
= (x+12)(x+6)//(x+8)/(x+3)
Hence, an expression to represent the perimeter of the rectangle with 10/(x² + 11x +24) and (x+1)/(x+3) would be (x+12)(x+6)//(x+8)/(x+3).

Have an amazing day!!
Please rate and mark brainliest!!
Answer:
\(7x^{25}\)
Step-by-step explanation:
Given sequence: \(7x, -7x^5, 7x^9\)
General form of a geometric sequence: \(a_n=ar^{n-1}\)
(where a is the first term and r is the common ratio)
\(a_1=7x\)
\(a_2=-7x^5\)
\(a_3=7x^9\)
To find the common ratio, divide one term by the previous term:
\(r=\dfrac{a_2}{a_1}=\dfrac{-7x^5}{7x}=-x^4\)
Therefore, substituting the found values of a and r into the formula:
\(\implies a_n=(7x)(-x^4)^{n-1}\)
To find the 7th term, substitute n = 7 into the formula:
\(\begin{aligned}\implies a_7 & =(7x)(-x^4)^{7-1}\\ & = (7x)(-x^4)^6\\ & = (7x)(x^{24})\\ & = 7x^{25}\end{aligned}\)
Consider the system of equations y + 2kz = 0 x + 2y + 6z = 2 kx + 2z = 1 where k is an arbitrary constant. (a) For which values of the constant k does this system have a unique solution? (b) For which values of the constant k does this system have no solution?
The system of equations has a unique solution when the determinant of the coefficient matrix is non-zero.
In this case, the coefficient matrix is:
| 0 1 2k |
| 1 2 6 |
| k 0 2 |
The determinant of this matrix is given by:
D = 0(2(2) - 0(6)) - 1(1(2) - 6(k)) + 2k(1(0) - 2(2))
= -12k + 12k
= 0
When the determinant is zero, the system may have infinitely many solutions or no solution. Therefore, we need to investigate further to determine the values of k for which the system has a unique solution.
(b) To determine the values of k for which the system has no solution, we can check if the rank of the coefficient matrix is less than the rank of the augmented matrix. If the ranks are equal, the system has a unique solution. If the ranks differ, the system has no solution.
By performing row reduction on the augmented matrix, we find that the ranks of both the coefficient matrix and the augmented matrix are equal to 2. Therefore, for any value of k, the system has a unique solution.
In summary, for all values of the constant k, the given system of equations has a unique solution and does not have any solution.

a regular heptagon has an apothem that is 3 inches in length. one of the sides has a length of 7 inches. what is the area of the heptagon?
The area of the Heptagon is 32.6
What is Heptagon?
A polygon having 7 sides and 7 angles are called a heptagon. The term "septagon" may also be used to refer to the heptagon. A heptagon is formed when all of its sides come together end to end. Therefore,
The heptagon's sides total seven.
What Is Meant by Apothem?
Apothem is a line traced from any polygon's center to one of its sides' midpoints.
The apothem formula, when the side length is given is:
\(a=\frac{S}{2 \tan \left(\frac{180}{n}\right)}\)
Where,
a = apothem length
s = side length
n = number of sides of a polygon.
In the given question,
we have;
s = 7 inches;
a = 3 inches;
n = 7;
So,
The apothem, when the side length is given is:
\(a=\frac{S}{2 \tan \left(\frac{180}{n}\right)}\)
\(a=\frac{3}{2 \tan \left(\frac{180}{7}\right)}\)

Combine like terms.
2x + 188 = 180
2x = 180 - 188
2x = - 8
x = -8/2
x = -4
x + 64 = -4 + 64 = 60
x + 45 = -4 + 45 = 41
Step-by-step explanation:
We know that the sum of all angles of a triangle is 180 °.
x + 45 + x + 64 + 79 ° = 180 °.
combine like terms
x + x + 64 + 45 + 79 ° = 180 °
2 x + 188 ° = 180 °
Subtract
2 x = 180 ° - 188 °
2 x = - 8 °
Divide
x = -8 ° / 2
x = - 4 °
x + 45 = - 4° + 45 ° = 41°
x + 64 = - 4° + 64 ° = 60 °
