What are the excluded factors of 2/ x(x-3)

1 answer:

7 0

Hey there!

The excluded factors of an equation are the values of x in which the result is undefined. This means, if the denominator or x(x-3) is equal to 0, then your solution would be undefined.

To find these values, set up this equation and solve for the possible values of x:
x(x-3)=0

To solve for one of the values, divide both sides by (x-3):
x(x-3)/(x-3)=0(x-3)

Because (x-3) would cancel on the left hand side of the equation, and on the right hand side, anything divided by 0 is 0, you should get:
x=0

Now that you have one of the excluded values, solve for the other:
First divide both sides by x:
x(x-3)=0
x-3=0

Finally, add -3 to both sides to get:
x=3

Therefore, your excluded values of x would be 0 and 3.

Hope this helps and have a wonderful day! :)

This is so confusing all of it makes no sense

Tom [10]

Answer:

D). $4\sqrt{2}$

Step-by-step explanation:

STEP 1a: Find the last angle of the triangle. ( which is angle A)

$A+90+45=180$

STEP 1b: Solve the equation for A by adding 90 and 45.

$A+135=180$

STEP 1c: Then Move all terms not containing A to the right side of the equation by subtracting 135 from both sides of the equation

$A=180-135$

STEP 1d: Subtract 135 from 180.

$A=45$

STEP 2a: Find side b next.

STEP 2b: The cosine of an angle is equal to the ratio of the adjacent side to the hypotenuse.

$cos(A)=\frac{adj}{hyp}$

STEP 2c: Substitute the name of each side into the definition of the cosine function.

$cos(A)=\frac{b}{c}$

STEP 2d: Set up the equation to solve for the adjacent side, in this case b.

$b=c*cos(A)$

STEP 2e: Substitute the values of each variable into the formula for cosine.

$b=8*cos(45)$

STEP 2f: Cancel the common factor of 2.

$a=4\sqrt{2}$

HOPE THIS HELPS!

-2.1b +5.3= b -- 3.1b + 5.3 does is have one solution or infinitely many solutions ? Why ?

pychu [463]

Answer: infinitely many solutions.

Step-by-step explanation:

Ok, our equation is:

-2.1*b + 5.3 = b - 3.1*b + 5.3

now, simplifyng the right side, we have:

b - 3.1*b + 5.3 = (1 - 3.1)*b + 5.3 = -2.1*b + 5.3

Then our initial expression is:

-2.1*b + 5.3 = -2.1*b + 5.3

So in both sides of the equality we have the exact same thing, so this is a trivial equality.

This means that the equality will remain true for any value of b, which means that we have infinitely many solutions.

Answer:

5.1

Step-by-step explanation:

you need to work backwards.

so do 17.5 + 8 then divide by 5 to get 5.1

Answer:

Suppose that A and B are points on the number line.

If AB=11 and A lies at 6, where could B be located?

If there is more than one location, separate them with commas
