Step-by-step explanation:

You need to remember that

$log( \frac{a}{b} ) = log(a) - log(b)$

and

$log(ab) = log(a) + log(b)$

then the solution is

$log( \frac{r}{st} ) = log(r) - log(st) \\ = log(r) - ( log(s) + log(t) ) \\ = log(r) - log(s) - log(t)$

Hi there!

$\large\boxed{\frac{1}{4}, -\frac{3}{2}}$

13y² + 10y - 3 = 5y²

Begin by moving all terms to one side:

13y² + 10y - 3 - 5y² = 0

Combine like terms:

8y² + 10y - 3 = 0

Factor using the guess-and-check method.

(4y - 1)(2y + 3) = 0

Set each factor equal to 0 to find the solutions:

4y - 1 = 0

4y = 1

y = 1/4

2y + 3 = 0

2y = -3

y = -3/2

amid [387]

Find each individual answer and add it together...

18 ones means 18*1=18

15 hundreds means 15*100=1500

15 tens means 15*10=150

8 thousands means 8*1000=8000

Add them...

8000+1500=9500

9500+150=9650

9650+18=<em><u>9668</u></em>

Explain How do you find factors of the polynomial

balandron [24]

Answer:

Step-by-step explanation:

"For a polynomial, no matter how many terms it has, always check for a greatest common factor (GCF) first. Literally, the greatest common factor is the biggest expression that will go into all of the terms. Using the GCF is like doing the distributive property backward.

If the equation is a trinomial — it has three terms — you can use the FOIL method for multiplying binomials backward.

If it’s a binomial, look for difference of squares, difference of cubes, or sum of cubes.

Finally, after the polynomial is fully factored, you can use the zero product property to solve the equation."

Trail mix is sold in 1-pound bags.Mary will buy some trail mix and repackage it so that each of the 15 members of her hiking clu

inessss [21]

Answer:

6 bags.

Step-by-step explanation:

We have been given that trail mix is sold in 1-pound bags. Mary will buy some trail mix and repackage it so that each of the 15 members of her hiking club gets one 2/5 bag.

Let us find the number of pounds Mary will need to give to 15 members. As Mary wants to give 2/5 of 1 ounce bag of trail mix, so she will need 15 times 2/5 ounces to given to 15 members of her hiking club.

$\text{Pounds of trail mix needed to give to 15 members}=15\times \frac{2}{5}\text{ ounce}$

$\text{Pounds of trail mix needed to give to 15 members}=3\times 2\text{ ounce}$

$\text{Pounds of trail mix needed to give to 15 members}=6\text{ ounces}$

So Mary needs 6 pounds of trail mix to give to 15 members of her hiking club. As trial mix is sold in 1-pound bags, therefore, Mary should buy 6 bags to have enough of trail mix without any trail mix left over.
