A(-5,-4) ——> A’ is a glide reflection where the translation is (x,y)—->(x+6,y), and the line of reflection is y=3. What ar

Nastasia [14]

Solution:

The Point in the coordinate plane is A(-5,-4).

Perpendicular or shortest Distance from line y=3 that is (-5,3) to point (-5,-4) is

$=\sqrt{(-5+5)^2+(3+4)^2}\\\\=7$

When it is reflected through the line, y=3, the coordinate of point A (-5,-4) changes to (-5,3+7)= B(-5,10).

Now, the Point B is translated by the rule , (x,y)—->(x+6,y),

So,the point B is translated to, (-5+6,10)=(1,10)

Option C: (1,10) is the glide reflection of point A(-5,-4).

A line passes through the point (0,-4) and has slope-5. What is the equation of the line in slope-intercept form?

Mazyrski [523]

Y= -5x -4 because you would do slope intercept form and sub the y and x in for -4 and 0

Find the value of this expression (50 - 2) ÷ 4 - 7² -40 -41 -37

UkoKoshka [18]

Answer:

The answer is -37.

Step-by-step explanation:

1) Simplify 50-2 to 48.

48 ÷ 4 - $7^{2}$

2) Simplify $7^{2}$ to 49.

48 ÷ 4 - 49

3) Simplify 48 ÷ 4 to 12.

$12 - 49$

4) Simplify.

$-37$

Therefor, the answer is Option C) -37.

If Matrix A has dimensions 1x3 and Matrix B has dimensions 3x4, can these be multiplied?

aalyn [17]

A=1x3 means 1 row and 3 columns.
B=3x4 means 3 rows and 4 columns.

AB is a compatible multiplication because A has three columns and B has 3 rows.

However, BA is not a compatible multiplication because B has 4 columns while A has only 1 row.

The general trick is if you read the row/column of the two matrices as 1-3-3-4, and the two middle ones are identical, then AB would be a compatible multiplication. On the other hand, BA would read 3-4-1-3, since 4 and 1 are not identical, so it is not a valid multiplication.

Do remember 1x3 means 1 ROW and 3 COLUMNS.
