What you must do for this case is to rewrite the expression in a simplified way.
 We have then:
 3/a-9b
 We take common factor 3:
 (3)*(1/a-3b)
 Answer:
 The simplified form of the expression is:
 (3)*(1/a-3b)

For what values of x and y must the figure have in order to be a parallelogram
erma4kov [3.2K]

<u>Given</u>:

Given that the parallelogram with the lengths 5x, 3x + 1, 2y - 5 and y.

We need to determine the values of x and y.

<u>Values of x and y:</u>

We know the property that the opposite sides of a parallelogram are congruent.

Thus, we have;

5x=2y-5 ------- (1)

3x+1=y  ------- (2)

The value of x and y can be determined using the substitution method.

Substituting equation (2) in equation (1), we have;

5x=2(3x+1)-5

5x=6x+2-5

5x=6x-3

-x=-3

  x=3

Thus, the value of x is 3.

Substituting x = 3 in equation (2), we have;

3(3)+1=y

    9+1=y

         10=y

Thus, the value of y is 10.

The probability density function f(x) of a random variable X that has a uniform distribution between a and b is:
Lunna [17]

The probability density function (pdf) is;

f(x)=\frac{1}{b - a} for a ≤ x ≤ b.

while the mean is given as \frac{a + b}{2}

And the standard deviation given as \sqrt{\frac{(b - a)^{2} }{12} }

Choose the correct simplification of the expression a^7b^8/a^4b^4
Alex787 [66]
The answer is B: a^3b^4<span>

Proof:
Simplify the following:
(a^7 b^8)/(a^4 b^4)

Combine powers. (a^7 b^8)/(a^4 b^4) = a^(7 - 4) b^(8 - 4):
a^(7 - 4) b^(8 - 4)

7 - 4 = 3:
a^3 b^(8 - 4)

8 - 4 = 4:
Answer:  a^3 b^4

PS: I just wish that you put the equation down as it's intended i.e.
a^7b^8/a^4b^4 is not the same as (<span>a^7b^8)/(a^4b^4)</span>
