Answer: x=4, x=-5

Step-by-step explanation:

\frac{x}{x-4}-\frac{4}{x+5}=\frac{36}{x^2+x-20}

Multiply everything by the LCM = (x-4)(x+5):

\frac{x}{x-4}\left(x-4\right)\left(x+5\right)-\frac{4}{x+5}\left(x-4\right)\left(x+5\right)=\frac{36}{x^2+x-20}\left(x-4\right)\left(x+5\right)

\frac{x\left(x-4\right)\left(x+5\right)}{x-4} -\frac{4\left(x-4\right)\left(x+5\right)}{x+5} =\frac{36\left(x-4\right)\left(x+5\right)}{\left(x-4\right)\left(x+5\right)}

Simplify by cancelling out same terms: in the numerators and denominators:

x\left(x+5\right)-4\left(x-4\right)=36

x^2+x-20=0

(x+5)(x-4) = 0

The solution to the quadratic equation is x=4, x=-5

Carrie is finding the set of even numbers within the set of prime numbers. She starts by considering only positive numbers. Of t
MArishka [77]

Answer:

Option 3 is correct that is prime numbers.

Step-by-step explanation:

Even numbers are those which are divisible by 2

Prime numbers are the numbers which are divisible by 1 and the number itself

Since, we have to take only positive numbers

Carrie has taken out the set of  even number within the set of prime number

So, 2 is the only number inside this eset because 2 is even as well as prime

Hence,universal set will be prime numbers

Therefore, Option 3 is correct that is prime numbers.

What are the coordinates of the terminal point for 8 = 330°?
galben [10]

Answer:

Step-by-step explanation:

If you plot this angle in the coordinate plane, you will find yourself in the fourth quadrant with a referencew angle of 30. Constructing the triangle from that reference angle and using the Pythagorean triple for a 30-60-90 triangle, you get that the side adjacent to the reference angle is √3, the side opposite the reference angle is a -1, and the hypotenuse (which is NEVER negative!) is 2. The x and y coordinates of the terminal point result from the cos (related to the x coordinate) and the sin (related to the y coordinate). The cos of 30:

cos(30)=\frac{\sqrt{3} }{2} and the sin of 30:

sin(30)=-\frac{1}{2} so the coordinates of the terminal point on that angle are

(\frac{\sqrt{3} }{2},-\frac{1}{2})

You could also just go to your unit circle, find the angle 330 and look at the coordiantes they give you there for (cos, sin). But I'm a high school math teacher so I wanted you to know how to find this outside of the unti circle. Cuz what if you lost it!?
