Answer:
(c) is the Correct answer of this
Step-by-step explanation:
First divide both sides by 2
then apply (a+b)^2 = a^2+b^2+2ab formula
solve quadratic equation
then apply discriminant formula
Hope you get it dear ☺️
Note: (f/g)(x) can be written as
f(x)/g(x). This simply means f(x) divided by g(x).
We know what f(x) and g(x) are because that information is given to us in the problem. See it?
Set up the rational function and factor.
(x^2 - 9)/(x^2 -4x + 3)
We now factor the top and bottom.
(x - 3)(x + 3)/(x - 3)(x - 1)
Cancel out common terms.
We now have (x + 3)/(x - 1) as the reduced rational function.
To find the domain, set the bottom to 0 and solve for x.
x - 1 = 0
x = 1
The domain is ALL REAL NUMBERS EXCEPT FOR 1. In the given function, x CANNOT BE 3 because this would create a zero in the denominator.
Answer in interval notation is
(-00, 1) U (1, 3) U (1, 00).
The interval notation reads as follows:
All negative numbers included but not 1 united with the open interval that does not include 1 and 3 united with the interval that excludes 1 but includes all positive numbers greater than 1. I hope this is clear.
First, let's divide by 4, since 4 can go into both the numerator and denominator.
56/4 = 14
100/4 = 25
That gives us 14/25.
That fraction can't be reduced further, so the simplest form of 56/100 is 14/25.
Hope that helped!
U= uniforms
598+ 24.25u= 1762
24.25u= 1762- 598
24.25u= 1164
U= 1164/24.25
U= 48
The school purchased 48 uniforms.
Hope this helps!
Answer:
N = -1/2
Step-by-step explanation:
We are adding in this, so we need to do the opposite to both sides, to get N by itself.
N + 3/4 - 3/4 = 1/4 - 3/4
N = -2/4 or, simplified, -1/2
