Find the slope of the line through each pair of points (19, -16), (-7,-15)

1 answer:

7 0

Equation: $\frac{ y_{2}-y_{1} }{x_{2}-x_{1}}$
plug the numbers into the equation:
((-15) - (-16)) / (-7) - (19)
(-15+16) / (-7-19)
1 / -28

The answer is -1/28

What is the recursive rule for the sequence?

Marrrta [24]

The next term is 1.4 larger than the one before it, so the appropriate choice is

$a_{n}=a_{n-1}+1.4 \quad\mbox{where}\ a_{1}=1.4$

_____

However, the description

$a_{n}=a_{n+1}-1.4 \quad\mbox{where}\ a_{1}=1.4$

also correctly describes the relationship between a1 and a2, for example. While this equation is technically correct, it is less useful to work with, so is probably not the expected answer.

Factor the trinomial below.

Ilia_Sergeevich [38]

Answer:

Step-by-step explanation:

yes, we need two numbers that multiplied with each other results in -48.

that means already that one of them has to be positive and the other negative.

that gives us (with all +/- alternating sign combinations)

2 and 24

3 and 16

4 and 12

6 and 8

to pick from there we see that the "middle" term is -2x.

that means that the absolute value of the negative number has to be 2 more than the positive number (so that when adding the intermediate multiplication terms we end up with -2x).

the only choice is therefore 6 and -8.

and that makes B the right answer.

Let's find the median!

Step-by-step explanation:

Numbers:

6, 2, 59, 12, 11, 9, 9, 54, 54, 46, 2, 32, 43, 11

In order from least - to - greatest:

2, 2, 6, 9, 9, 11, 11, 12, 32, 43, 46, 54, 54, 59

What is the median of 11 and 12?

<h3>The median of 11 and 12 is 11.5, or 11 - and - a - half.</h3>

I hope this helps!

A company estimates that its cost and revenue can be modeled by the functions C)-0.75x+20,000

lisabon 2012 [21]

Let C(x) = -0.75x + 20,000 and R(x)= -1.50x then the profit function exists noted as P(x) = R(x) - C(x)

P(x) = -1.50x - (-0.75)x + 20,000

P(x) = -0.75x + 20000

Therefore, the profit function exists -0.75x + 20000.

<h3>How to find profit function?</h3>

The profit function can be estimated by subtracting the cost function from the revenue function. Let profit be expressed as P(x), the revenue as R(x), the cost as C(x), and x as the number of items traded. Then the profit function exists noted as P(x) = R(x) - C(x).

Given:

C(x) = -0.75x+20,000 and R(x)= -1.50x

P(x) = R(x) - C(x)

= -1.50x - (-0.75)x + 20,000

= -1.50x + 0.75x + 20,000

Apply rule -(-a) = a

= -1.5x + 0.75x + 20000

Add similar elements:

-1.5 x + 0.75x = -0.75x

P(x) = -0.75x + 20000

Therefore, the profit function exists -0.75x + 20000.

What is the equation, in standard form, of a circle with center (−5, 8) and radius 5?

skad [1K]

Answer:

( x + 5 )² + ( y - 8 )² = 25

Step-by-step explanation:

Standard form for the equation of a circle - ( x - h )² + ( y - k )² = r²

Where r = radius and Center is located at ( h , k )

We are given that the center is at ( -5 , 8 )

Thus, h = -5 and k = 8

We are also given that the radius = 5

Thus, r = 5

Now we just plug all of the given values into the standard form equation

( x - (-5))² + ( y - 8 )² = 5²

*simplify*

in - ( - 5 ) the two negative sign cancel out and it turns into + 5

5² = 25

Thus, the equation is ( x + 5 )² + ( y - 8 )² = 25
