How do I do this? I need help really bad. Can someone help me with this question?

Answer: C

Step-by-step explanation:

3x-3 ≥ 0 ==> x ≥ 1

3x+6 ≥ 0 ==> x ≥ -2

So: condition x ≥ 1

[tex]\sqrt{3x-3} +1=\sqrt{3x+6} \\\\\sqrt{3x+6} -\sqrt{3x-3} =1 \ squaring\\\\3x+6+3x-3-2\sqrt{(3x+6)(3x-3)} =1\\\\6x+2=2\sqrt{(3x+6)(3x-3)}\\\\\sqrt{(3x+6)(3x-3)}=3x+1\ squaring \\\\(3x+6)(3x-3)=(3x+1)^2\\\\9x^2+18x-9x-18=9x^2+6x-1\\\\3x=19\\\\x=\dfrac{19}{3} \\\\sol=\{\dfrac{19}{3}\}\\\\Answer\ C\\[/tex]

Matrix operations includes the addition, multiplication and subtraction of matrices

The correct option for the matrix that can be used to represent B is option D)

[tex]D) = \left[\begin{array}{rrr}6&-3&-6\\5&9&5\end{array}\right][/tex]

The reason the above option is correct is as follows:

From the graph, we have that the coordinates of the preimage are;

(-6, 5), (-3, 9), and (6, 5)

The coordinates of the preimage in matrix form is given as follows;

[tex]\left[\begin{array}{rrr}6&-3&-6\\5&9&5\end{array}\right][/tex]

The coordinates of the image are;

(-6, -5), (-3, -9), and (6, -5)

The coordinates of the image in matrix form is given as follows;

[tex]\left[\begin{array}{rrr}6&-3&-6\\-5&-9&-5\end{array}\right][/tex]

The above image matrix can be obtained from the primage matrix as follows:

[tex]\left[\begin{array}{rrr}1&0\\0&-1\end{array}\right]\left[\begin{array}{rrr}6&-3&-6\\5&9&5\end{array}\right] = \left[\begin{array}{rrr}6&-3&-6\\-5&-9&-5\end{array}\right][/tex]

Which is of the form AB = C

Where;

[tex]A = \left[\begin{array}{rrr}1&0\\0&-1\end{array}\right][/tex]

[tex]B = \left[\begin{array}{rrr}6&-3&-6\\5&9&5\end{array}\right][/tex]

[tex]C = \left[\begin{array}{rrr}6&-3&-6\\-5&-9&-5\end{array}\right][/tex]

Therefore, the matrix that could represent B is [tex]\left[\begin{array}{rrr}6&-3&-6\\5&9&5\end{array}\right][/tex] which is option D)

Answer:

8 and 24

Step-by-step explanation:

let one no. be x

and another be 3x

Their sum = 32

Now,

x + 3x=32

4x=32

x=32/4

x=8

Hence, one number is x =8 and another is 3x = 3*8=24

The two numbers are 6 and 26

From the given statement, we can form the following equations;

Let the first number = x

let the second number = y

The  2 numbers that add up to 32:

x + y = 32 ---------- (1)

If one number is eight more than three times the other:

x = 3y + 8  -------(2)

Substitute the value of x into equation (1) and solve for the second number

3y + 8 + y = 32

4y = 32 - 8

4y = 24

[tex]y = \frac{24}{4} = 6[/tex]

The value of  the first number, x,  is calculated as;

x = 3(6) + 8

x = 18 + 8

x = 26

Thus, the two numbers are 6 and 26

Answer:

Step-by-step explanation:

Subtract both sides by 4w

q - 4w = 4n

Divide both sides by 4

n = q - w

Answer:

y = -3x - 4

Step-by-step explanation:

-3x - y = 4

~Add 3x to both sides

-y = 4 + 3x

~Divide -1 to everything

y = -4 - 3x

~Reorder

y = -3x - 4

Answer:

x= (5X+3) DEGREES = 90 degrees (right angle)

5x=90 degrees - 3 degrees =87 degrees

5x÷5 =87 degrees ÷ 5

x=17.4 degrees

we now know our angles x = 17.4 degrees so we can know substitute into the give formula

wxz=5 (17.4)+ 3

wxz =90 degrees

zxy=we know the size of x

zxy=

8 (17.4)-4

zxy=135.2 degrees

Answer:

Yes

Step-by-step explanation:

Cross multiply

6/9 = 10/15

6 x 15 = 90

10 × 9 = 90

so yes they consist of equivalent fractions. cross multiplying is a simple way to find out if fractions are equivalent.

Step-by-step explanation:

Point (9, 6) would be on the inverse of this function so option (D) will be correct.

A certain kind of relationship called a function binds inputs to essentially one output.

A function can be regarded as a computer, which is helpful.

The machine will only accept specified inputs, described as the function's domain, and will potentially produce one output for each input.

Given the sets of coordinates of a function.

An inverse function is the reciprocal of a function and the coordinate of the inverse function is interchanged with the original function.

For example, if (x,y) is the coordinate of the function then (y,x) will be the coordinate of the inverse of the function.

Since option (D) (9, 6) is the interchange of (6,9) so it will be the inverse of a function.

Hence "Point (9, 6) would be on the inverse of this function".
