Of course you could solve for x. The LCD of these three fracgtions is (x-2)(x+2)(x).

However, you could identify the correct answer by subbing the given x values into the original equation of fractions. For example, if you want to test out x = -4/3 and x = -5, focus on one or the other first. If x = -4/3

then the first fraction becomes

------------- Calculate the other 2 fractions for x = -4/3. Is the resulting
-4/3 - 6/3 equation then true?

THe LCD is x(x^2 - 4)

so multiplying through by this we get:-

2x(x + 2) + 7x = 5(x^2 - 4)
2x^2 + 4x + 7x = 5x^2 - 20
3x^2 - 11x - 20 = 0

(3x + 4)(x - 5 ) = 0

so x = 5 , -4/3

Its the second choice

Check all solutions to the equation. If there are no solutions, check "None."x2=0A. 1B. -1C.0D. 10E. 4E None

The given equation is,

$\begin{gathered} x^2=0 \\ x=0 \end{gathered}$

Thus, option (C) is the correct solution.

I’ll give brainleyyyyyyy

Ira Lisetskai [31]

Answer:

0, -2, 2, -1

Step-by-step explanation:

You are trying to make it so that the one of the ( )= 0.

An example is (x+15) or (2x+3)

the first l one would be x= -15 since -15+15 would equal 0.

The second one is -3/2 since it would be -3+3 which would equal 0.

also since the equation starts with x( or -x it doesn't really matter) one of the zeros would also be 0.

Hope this helps!

I don't know how many thousandths go in 5,000 ones

Verizon [17]

5,000,000 is the answer.
5,000÷0.001=5,000,000

Find the range of the graphed function.

rusak2 [61]

Range is set of all y-values. To find a range of graphed function, we need to know that range starts from the minimum value of graph to maximum value. That's because the minimum value is the least value that you can get by substituting the domain and the maximum value is the largest value that you can get by substituting the domain as well.

Now we don't talk about domain here, we talk about range. See the attachment! You are supposed to focus on y-axis, plane or vertical line. See how the minimum value of function is the negative value while the maximum value is positive.

That means any ranges that don't contain the negative values are cleared out. (Hence A and C choices are wrong.)

Next, range being set of all real numbers mean that graphed functions don't have maximum value or minimum value (We can say that both max and min are infinite.)

Take a look at line graph as an example of range being set of all real numbers, or cubic function.

Answer/Conclusion

The range exists from negative value which is -9 to the maximum value which is 5.
That means the range is -9<=y<=5

The object of the game is to toss a beanbag in the circular hole of a 48-by-24-inch board. If the diameter of the circle is 6 in

larisa [96]

Answer:

Geometric probability of an object hitting a circular hole is 0.0245.

Step-by-step explanation:

We have given,

A board of size 48 by 24 inch. There is a circular hole in the board having diameter 6 inches.

So,

Area of a board = 48 × 24 = 1152 square inches

And area of circular hole = π×r² {where r = diameter/2 = 6 / 2 = 3 inches}

Area of circular hole = π×3² = 9π = 28.27 square inches

Now, we need to find the geometric probability of an object will hit the circle.

Geometric probability = Area of circular hole / Area of board

Geometric probability = $\frac{28.27}{1152}$

Geometric probability = 0.0245

hence geometric probability of an object hitting a circular hole is 0.0245.
