PEMDAS = Parentheses, Exponents, Multiplication, Division, Addition, Subtraction
First, subtract the numbers in the parentheses, then multiply by 11.
(12 - 9) = (3)
3 x 11 = 33
19 + 11 - 12^2 ÷ 3(33) - 7
Now, just multiply 33 by 3, and then square 12 (12 x 12).
19 + 11 - 144 ÷ 99 - 7
Now, you can divide 144 by 99, this is an infinite number, so..
144 ÷ 99 = 1.455
19 + 11 - 1.455 - 7
Finally add, then subtract.
30 - 1.455 - 7
28.545 - 7
The final answer is 21.545.
I believe it should be b I’m not 100% sure tho :/
Option A
The line is perpendicular to
<u>Solution:</u>
Given that line is
We have to find the line perpendicular to this line.
The given line equation is in form of slope-intercept form
<em><u>The slope-intercept form is given as:</u></em>
y = mx + c
Where "m" is the slope of the line and "c" is the y-intercept
On comparing the given equation with slope-intercept form, we get
<em>If a line is perpendicular to another line, then the product of their slopes will always be -1</em>
Let the slope of line which is perpendicular to given line be "a"
Then we get,
Now look at the options and compare with slope intercept form and find out which option has the slope "m" =
Option A has the slope
Thus option A is correct

Answer:
Depends on what number(s)/fraction(s) your working with.
Step-by-step explanation:
Find the reciprocal of a fraction by flipping it. The definition of "reciprocal" is simple. To find the reciprocal of any number, just calculate "1 ÷ (that number)." For a fraction, the reciprocal is just a different fraction, with the numbers "flipped" upside down (inverted).
