Answer:

Option (c) is correct.

Add a constant to a row does not involves while solving a system of equations using matrix.

Step-by-step explanation:

Given : solving a system of equations.

W have to choose from given options that can not be used on a matrix when solving a system of equations.

Since solving the system using matrix method involve

1) adding of rows,

2) multiplying a row by a constant.

3) interchange rows

But add a constant to a row does not involves while solving a system of equations using matrix.

Thus, Option (c) is correct.

If f(x) = 7x- 6, which of the following is the inverse of kx)?

Yanka [14]

Step-by-step explanation:

$f(x) = 7x - 6$

$\:$

<u>Inverse</u>

$y = 7x - 6$

$x = 7y - 6$

$x + 6 = 7y$

$y = \frac{x + 6}{7}$

${f}^{ - 1} (x) = \frac{x + 6}{7}$

Please Find the value of x and y

Free_Kalibri [48]

Answer: x=40° and y=140°

Step-by-step explanation:

From the figure, we know that x and 40 are vertical angles. Therefore, they are equal to each other.

x=40°

With the value of x, we know that x and y are supplementary angles. That means they are equal to 180°.

40+y=180 [subtract both sides by 40]

y=140°

Now we know x=40° and y=140°.

Forty-two of the students in band own their instrument.

goldfiish [28.3K]

Answer:

112 students

Step-by-step explanation:

Let T be the total number of students in the band.

From the question,

We were told that 37.5% of the total owns their individual instruments and this amount to 42 students

The total number of students can calculated for as follows:

37.5% x T = 42

37.5/100 x T = 42

Cross multiply to express in linear form

37.5 x T = 100 x 42

Divide both side by 37.5

T = (100 x 42) /37.5

T = 112

Therefore, there are 112 students in the band
