Answer:

-18y - 18

Step-by-step explanation:

The -2 needs to be distributed into both values in the parenthesis. This will make the equation -8y - 10y - 18. Then, you put the like terms together. This will result in the final equation, -18y - 18

How do i solve this equation 5x-3y=12 for y

I am Lyosha [343]

We have such equation
5x-3y=12 /-5x (subtract 5x both sides)
5x-5x-3y=12-5x
-3y=-5x+12 /:3 divide both sides by 3
-y= $\frac{-5x+12}{3}$ /*(-1) multiply both sides by -1
y=- $\frac{-5x+12}{3}$
y= $\frac{5x-12}{3}$ - its the answer

What is .00463 in fraction form

Amiraneli [1.4K]

We have a decimal system.

After the decimal point starts the negative powers of ten in those columns...

. 10^-1, 10^-2, 10^-3, 10^-4, 10^-5

1/10s, 1/100s, 1/1000s, 1/10,000s, 1/100,000s

so .00463 is equal to

463/100000

The elements of Matrix C are shown below.

sergeinik [125]

The matrix that represents the matrix D is $\left[\begin{array}{cccc}3&1&-9&8\\2&2&0&5\\16&1&-3&11\end{array}\right]$

<h3>How to determine the matrix d?</h3>

Given the elements of the matrix C.

The matrix c is represented by its rows and columns element, and the arrangements are:

C11 = 3 C12 = 1 C13=-9 C14 = 8

C21 = 2 C22=2 C23 =0 C24 = 5

C31 = 16 C32 = 1 C33=-3 C34=11

Remove the matrix name and position

3 1 9 8

2 2 0 5

16 1 -3 11

Represent properly as a matrix:

$C = \left[\begin{array}{cccc}3&1&-9&8\\2&2&0&5\\16&1&-3&11\end{array}\right]$

Matrix C equals matrix D.

So, we have:

$D = \left[\begin{array}{cccc}3&1&-9&8\\2&2&0&5\\16&1&-3&11\end{array}\right]$

Hence, the matrix that represents matrix D is $\left[\begin{array}{cccc}3&1&-9&8\\2&2&0&5\\16&1&-3&11\end{array}\right]$
