Step-by-step explanation:
I believe it would be c
This is because when you have to find a line that is perpendicular you have to flip the nominator and denominator and then change the sign so if it’s negative switch it to positive
I hope that makes sense and I hope it is right

Step-by-step explanation:
<u>Step 1: Define</u>
x/5 - 1 = 10
<u>Step 2: Solve for </u><em><u>x</u></em>
- Add 1 to both sides: x/5 = 11
- Multiply 5 on both sides: x = 55
Hey there! :)
-(3x)² + 3 = -6
Simplify.
-(9x²) + 3 = -6
Simplify.
-9x² + 3 = -6
Subtract 3 from both sides.
-9x² = -6 - 3
Simplify.
-9x² = -9
Divide -9 from both sides.
-9x² ÷ -9 = -9 ÷ -9
Simplify.
x² = 1
So, x = 1 OR x = -1

To the best of my knowledge, this is what I gather the table's values mean:
"antibodies present" and "positive" give you the percent of people who had the antibodies and the tests showed they did (hence, positive).
"antibodies present" and "negative" give you the percent of people who did have the antibodies, yet the tests read otherwise (misdiagnosed, negative when it should be positive).
"antibodies not present" and "positive" also show a percentage of people who were misdiagnosed. these people did not have the antibodies yet they tested positive for them.
"antibodies not present" and "negative" show the percent of people who did not have the antibodies and who were tested to prove just that.
