Answer:

Answer:

-63

Step-by-step explanation:

Because -9 x 7 = -63. If the signs are different then it will be negative. -9 x 7 = -63 is the same like 9 x 7 = 63. I hope this answer your question!

30 former classmates gathered to celebrate the anniversary of their school graduation. Each of them greeted and shook hands with every other without any exceptions how many handshakes were exchanged when everyone was finished?Note: When person A shakes with person B, person B is also shaking with person A. It is counted as one handshake.

Answers

Let's pick one person at random and call it the 'first'.

That person shakes hands with 29 other classmates.

Take another person different from the first, we'll call him the 'second'. Since he has already shaken hands with the first, he shakes hands with 28 other classmates.

The 'third' person will likewise shake hands with 27 other classmates, and so on.

Hence, the total number of handshakes is 29+28+27+...+2+1 = 29*30/2=435 handshakes

The answer is 435 handshakes when everyone was finished. I hope this is correct.

I need help with slope

Answers

We should know the slope formula:

m=(y2- y1)/(x2-x1)

Now plug in the points accordingly:
=(-1-4)/(1-(-4))
=(-5)/(5)

It can be simplified further:
(-5)/(5) = -1

Slope of the line that passes through (-4,4)  and (1,-1) is -1

there are 225 wolves in a state park the population is increasing at the rate of 15% per year you want to make a prediction for how long it will take the population to reach 500

Answers

Well, here is how i would do it.

We start with 225, at a rate of 15% per year. Assuming your answers are in years and not months, we will increase by this increment; years.

So, we start with 225, and a 15%, or .15, increase. So what we would do, it take 225 times .15. One way ive learned to do this (via algebra class) is that you can times it by 1.15 to make it quicker, this just takes out the adding step.

So after one year, we would have a total of 258.75, or about 259 wolves.

after two years, we would have about 298 (we cant have a half of a wolf!)

after 3 years, we would have about 343 wolves.

after 4 years, we would have about 394 ish

after 5 years, we would have about 453

after 6 years, we would have about 521.

So, it would take about 5 and a half years, if thats an option choice.

125x^3+343y^3

Answers

Final answer:

The expression 125x^3+343y^3 can be factored using the sum of cubes formula to obtain (5x+7y)(25x^2 -35xy + 49y^2).

Explanation:

The expression 125x^3+343y^3 is a sum of two cubes. The formula to factor a sum of cubes, a^3 + b^3, is (a+b)(a^2-ab+b^2). In this case, a is 5x and b is 7y, as (5x)^3 = 125x^3 and (7y)^3 = 343y^3. So, we apply the formula to obtain: (5x+7y)((5x)^2 - (5x)(7y) + (7y)^2), which simplifies to (5x+7y)(25x^2 -35xy + 49y^2).

Therefore, the factored form of the expression 125x^3+343y^3 is

= (5x+7y)(25x^2 -35xy + 49y^2).

Answer:

(5x + 7y)(25x² - 35xy + 49y²)

Step-by-step explanation:

125x³ + 343y³ ← is a sum of cubes and factors in general as

a³ + b³ = (a + b)(a² - ab + b³) , thus

125x³ + 243y³

= (5x)³ + (7y)³

= (5x + 7y)((5x)² - 5x(7y) + (7y)² )

= (5x + 7y)(25x² - 35xy + 49y²)

josh wanted to buy a bicycle but didn't have enough money. After josh told his troubles to sam slick, sam said,"I can fix that. see that fence? each time you jump that fence, i'll double your money. There's one small thing though: you must give me $32 each time for the priviledge of jumping." Josh agreed, jumped the fence, received his payment from sam slick, and paid sam $32. Repeating the routine twice more, josh was distressed to find that, on the last jump,after sam had made his payment to josh, josh had only $32, with which to pay sam and so had nothing left. Sam, of course, went merrily on his way, leaving josh wishing that he had known a little more about mathematics.
