Option c : 9 is the answer.
Explanation:
The expression is 
We need to determine the subtracted value of the expression.
From the expression we can see that the expression contains two negative signs.
To simplify the expression, we know that, When we multiply two negative numbers then the product is always positive.
This means 
Thus, the expression can be written as
Adding the two numbers, we get,
Thus, the value of the expression is 9.
Hence, Option c is the correct answer.
Answer:
2/ 15
Step-by-step explanation:
since the probability is 16/ 120
then we simplify it till it gets 2/15
hope this helps
and good luck!
I leaerned this neat trick
you don't need to convert to vertex form
where
y=ax^2+bx+c
the x value of the vertex is -b/2a
the y value is found by inserting the x value of the vertex into the equation
so
1x^2-6x+14
-b/2a=-(-6)/2(1)=6/2=3
plug that in
y=x^2-6x+14
y=3^2-6(3)+14
y=9-18+14
y=5
the vertex is (3,5)
Original price would be $675
$20 multiply 15 to get $300 being taken off.
add 300 to 375 you get $675
50/8 can be simplified by dividing top and bottom by 2, getting 25/4. this is also equal to 6 and 1/4
