The domain is {-9,-4,3,9} and the range is {2}.

Inserting 7 into the function, you get f(7)=2*7 which is 14. Therefore, someone can complete 14 guitar lessons in 7 months.

Find the LCD for the following fractions: , 25x3 60x3 25x5 60x5

zimovet [89]

Answer:

We need to find the lowest common divisor which is the smallest possible number that is dividable by ALL numbers.

We have the following numbers:

$\frac{25}{3}$

$\frac{60}{3}$

$\frac{25}{5}$

$\frac{60}{5}$

For the denominators (3, 3, 5, 5) the least common multiple (LCM) is 15.

LCM(3, 3, 5, 5) . Therefore, the least common denominator (LCD) is 15.

Rewriting the original inputs as equivalent fractions with the LCD:

125/15, 300/15, 75/15, 180/15

700.000 = 7 . 10 . 10 . 10 . 10 . 10

We know that equal bases sum the exponents, so,

7 . 10^(1 + 1 + 1 + 1 + 1)

7 . 10^5 = 700.000

But we can also say:

(7 . 10) . 10^4

(70 . 10) . 10³

(700 . 10) . 10²

(7000 . 10) . 10

As we can see, the alternative C shows (7 . 10) . 10^4 which can be a correct ans, so, alternative C.
