IceJOKER [234]
One variable is the amount of days. Lets call the amount of days D. Another variable is the amount of pictures left. Lets call this p. In this case, since Emanuel is deleting 20 pictures a day, and he has 745 picture to start with, the equation would be 745- 20D=p.

Which expression is equivalent to r to the 9th over r to the 3rd
alisha [4.7K]

Answer:

r^{6}

Step-by-step explanation:

To make this a bit easier to see, we'll expand that expression.

R to the 9th is just r times itself 9 times. R to the third is r times itself 3 times.

(excuse my bad formatting)

<u>The expression:</u>

<u>r • r • r • r • r • r • r • r • r • 1</u>

             r • r • r • 1

Remember, anything and everything has a coefficient or denominator of 1.

So, we can cancel 3 r's from the numerator and denominator.

<u>r • r • r • r • r • r • 1</u>

             1

Simplify....

\frac{1r^{6}}{1}

That just equals r^{6}.

Find the distance between the two points (-4, -5) and (1, -2).
Sphinxa [80]

Answer:

B

Step-by-step explanation:

Calculate the distance d using the distance formula

d = √ (x₂ - x₁ )² + (y₂ - y₁ )²

with (x₁, y₁ ) = (- 4, - 5) and (x₂, y₂ ) = (1, - 2)

d = \sqrt{(1+4)^2+(-2+5)^2}

  = \sqrt{5^2+3^2}

  = \sqrt{25+9}

  = \sqrt{34} → B
