Answer:

\frac{y-x}{x+y}

Step-by-step explanation:

We are given that fraction

\frac{\frac{1}{x}-\frac{1}{y}}{\frac{1}{x}+\frac{1}{y}}

We have to find the expression which is equivalent to given  fraction .

\frac{1}{x}-\frac{1}{y}=\frac{y-x}{xy}

\frac{1}{x}+\frac{1}{y}=\frac{x+y}{xy}

Substitute the values  then, we get

\frac{\frac{y-x}{xy}}{\frac{y+x}{xy}}

We know that

\frac{\frac{a}{b}}{\frac{x}{y}}=\frac{a}{b}\times \frac{y}{x}

Using the property then, we get

\frac{y-x}{xy}\times \frac{xy}{x+y}

\frac{y-x}{x+y}

This is required expression which is equivalent to given expression.

Nick has located several digging spots that his dog, Rico, has made in the backyard. To remember where all the spots were, Nick
Vinvika [58]

Answer:

  • See the graph attached an example below chosing three pairs or points.

Explanation:

I graphed the spots. Please, see the graph attached.

To calculate the distance between to points you use the distance formula:

      distance=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}

Selecting some points, this is how you calculate the distance:

  • (-4,3) and (5,3)

      distance=\sqrt{(5-(-4))^2+(3-3)^2}=\sqrt{9^2}=9

  • (-4,3) and (5,-1)

      distance=\sqrt{(5-(-4))^2+(3-(-1))^2}=\sqrt{9^2+4^2}=\sqrt{90}\approx9.5

  • (-4,-2) and (2,1)

       distance=\sqrt{(2-(-4))^2+(1-(-2))^2}=\sqrt{6^2+3^2}=\sqrt{45}\approx6.7

Thus, the order of the distances, for those pairs of points, ranked from longest to shortest are:

  • AG > AB > BF

Landry earned $2,300 over the summer and decided to invest it in an account that earns 4% annual compound interest. If Landry do
solniwko [45]

Answer:

Landry will have $5039.58

Step-by-step explanation:

compound interest formula: amount = p(1 + \frac{r}{n})^{nt}

p= principal ($2,300)

r= interest rate as a decimal (4% = 0.04)

n= number of times the principal is compounded per year (annually = once per year so 1 time per year)

t= time in years (20 years)

new equation: amount = 2300(1+\frac{0.04}{1} )^{1*20}

That equation equals $2,739.58 which you add to the principal.

$2,739.58 + $2,300 = $5039.58

hope this helps :) the equations aren't showing up right :(
