Answer:
(-2, 4.5)
Step-by-step explanation:
The midpoint formula is 
(-5+1/2, 3+6/2)
(-4/2, 9/2)
Your answer will be (-2, 4.5)
False positives are positive results from the test of a non-infected person, which happens 100-97=3% of the time, choice C.
You have to get a variable by itself like in here... Y is itself so in the other equation or we can say second one you just have to sub it in... Like
2x+5(-3x-2)=16
2x-15x-10=16
Now you just have to subtract 2 from 15, because of the same variable that is (x)
So -13x-10=16
Take 10 to the other side means add from the both sides, that will get you at
-13x=26
So now x= -2
Remember you added because it was -10 if it would be a positive 10 then you have to subtract it from both of the sides but since here it was negative so you just added them up
Hope i helped
20 - (4xn) = 4 is the equation
Answer:
