Use PEMDAS

P Parentheses first

E Exponents (ie Powers and Square Roots, etc.)

MD Multiplication and Division (left-to-right)

AS Addition and Subtraction (left-to-right)

3 ⋅ 12 − 12 = 36 - 12 = 24

3 ⋅ [26 − 2 ⋅ (3 + 6)] = 3 · (26 - 2 · 9) = 3 · (26 - 18) = 3 · 8 = 24

<h3>Answer: =</h3>

Which matrix is equal to P + Q?

Afina-wow [57]

Answer:
$\begin{bmatrix}-1.1 & 9.5\\-5.7 & 0.8\\6.1 & 0.7\end{bmatrix}$

------------------------------------

Add up the corresponding elements

Row1,Column1: 6.1+(-7.2) = -1.1
Row1,Column2: 1.9+7.6 = 9.5
Row2,Column1: -7.5+1.8 = -5.7
Row2,Column2: 2.2+(-1.4) = 0.8
Row3,Column1: 3.8+2.3 = 6.1
Row3,Column2: -1.4+2.1 = 0.7

So that's why the answer is
$\begin{bmatrix}-1.1 & 9.5\\-5.7 & 0.8\\6.1 & 0.7\end{bmatrix}$

Using the functions s = 13.5h, which statement is true?

Archy [21]

A function is a relationship between inputs where each input is related to exactly one output.

The domain of s = 13.5h are (0, 1, 2, 3, 4).

The range of s = 13.5h are (0, 13.5, 27, 40.5, 54).

<h3>What is a function?</h3>

A function is a relationship between inputs where each input is related to exactly one output.

Example:

f(x) = 2x + 1

f(1) = 2 + 1 = 3

f(2) = 2 x 2 + 1 = 4 + 1 = 5

The outputs of the functions are 3 and 5

The inputs of the function are 1 and 2.

We have,

s = 13.5h

For h = 0,

s = 0

For h = 1,

s = 13.5

For h = 2,

s = 27

For h = 3,

s = 40.5

For h = 4,

s = 54

We see that,

The domain of s = 13.5h are (0, 1, 2, 3, 4).

The range of s = 13.5h are (0, 13.5, 27, 40.5, 54).

Thus,

The domain of s = 13.5h are (0, 1, 2, 3, 4).

The range of s = 13.5h are (0, 13.5, 27, 40.5, 54).

Explain what would happen to a figure if you transformed it using the rule(x-2,y+4). Then state whether the image would be simil

Serggg [28]

Answer:

The figure would move 2 units to the left and 4 units up and the image would be congruent.

Step-by-step explanation:

If you transformed a figure using the rule (x-2, y+4).

Then the figure would move 2 units to the left (x-2) and 4 units up (x+4).

Similar figures would have the same shapes but different sizes.

Congruent figures would have the same shapes and same sizes but might be rotated.

Figures can not be both similar and congruent.

Moving the whole shape will not change the size; therefore, the figures would be congruent.
