Simplify the expression, show your work
Mila [183]

Answer:

\dfrac{-y(2x^2 + y)}{x(6x - 5y^2)}

Step-by-step explanation:

\dfrac{\frac{1}{x^2}+\frac{2}{y}}{\frac{5}{x}-\frac{6}{y^2}} =

To eliminate the denominators of the main numerator and denominator, we multiply the numerator and denominator of the main fraction by the LCD of all small denominators.

The LCD of x^2, y, x, and y^2 is x^2y^2.

= \dfrac{x^2y^2 \times (\frac{1}{x^2}+\frac{2}{y})}{x^2y^2 \times (\frac{5}{x}-\frac{6}{y^2})}

= \dfrac{y^2 + 2x^2y}{5xy^2 - 6x^2}

= \dfrac{y(y + 2x^2)}{x(5y^2 - 6x)}

= \dfrac{-y(2x^2 + y)}{x(6x - 5y^2)}

Which exponential equation is equivalent to this logarithmic equation?
Lubov Fominskaja [6]

Answer:

\displaystyle B)x  =  {5}^{9}

Step-by-step explanation:

we are given a logarithmic equation

\displaystyle   \log_{5}(x)  -   \log_{5}(25)  = 7

simplify the log:

\displaystyle   \log_{5}(x)  -2 = 7

add 2 to both sides:

\displaystyle   \log_{5}(x)  = 9

remember that,

\displaystyle   \log_{a}(b)  = c \iff   {a}^{c}  = b

so we obtain:

\displaystyle   x  =  {5}^{9}

hence,

our answer is B)

What's 80÷7 I need this answer fast thank you it's for 65 points
klemol [59]
In order to solve this, we must find out how many times 7 goes into 80. We can do this by either subtracting individual 7s from 80, or by adding 7s together until we cannot add another without going past 80.

For this answer, I will use the addition method.

7 + 7 = 14

14 + 7 = 21

21 + 7 = 28

28 + 7 = 35

35 + 7 = 42

42 + 7 = 49

49 + 7 = 56

56 + 7 = 63

63 + 7 = 70

70 + 7 = 77

From 77, we cannot add another 7 to it without going over 80, since 77 + 7 = 84.

So, let's count the sevens that we have added up so far, and when we do, we can see that there are 11 of them, adding up to 77.
So 7 goes into 80 11 times. Now, let's find the remainder...

To find the remainder, you just need to subtract the final added number from the number you are dividing from.

80 - 77 = 3

80 / 7 = 11, remainder 3
