What is the slope to this?

Let f(x)=x+a/x+b such that f(f(1)=0 & f(2)=-3 then a&b resctivily are.

Yuliya22 [10]

Answer:

The value of a = - 1 , And b = $\frac{ - 7 }{3}$

Step-by-step explanation:

Given as :

Function f(x) = $\frac{(x + a)}{(x + b)}$

And f(f(1)) = 0 And f(2) = - 3

Now For , x = 2 , y = - 3

I.e f(2) = $\frac{(2 + a)}{(2 + b)}$

or, - 3 = $\frac{(2 + a)}{(2 + b)}$

I.e 2 + a = - 6 - 3b

Or, a + 3b = - 8 ....... 1

Again f(f(1)) = 0

So, $\frac{(1 + a)}{(1 + b)}$ = 0

Or, 1 + a = 0

∴ a = - 1

So , put htis value of a i n eq 1 , we get value of b

So , - 1 + 3b = - 8

Or, 3b = - 7

∴ b = $\frac{ - 7 }{3}$

Hence The value of a = - 1 , And b = $\frac{ - 7 }{3}$ Answer

BRAINLIEST AND 39 POINTS

Veronika [31]

You have 10 numbers to choose from, and you're choosing 4 from that pool. Order of the numbers matters, because having 1234 as a PIN is not the same having it be 1324, so we're counting the number of permutations of 10 digits taken 4 at a time. So there are

$4!\dbinom{10}4=4!C(10,4)=4!C^{10}_4=\dfrac{10!}{(10-4)!}=5040$

possible PINs that can be made.

ivann1987 [24]

Answer:

19 in.³

Step-by-step explanation:

We have been given that Jay created a model of a building from two rectangular prism. One building has a volume of 15 Cubic inches. The model had a total volume of 34 in.³ We are asked to find the volume of the other building.

We know that total volume of model will be equal to sum of volume of two buildings.

$\text{Volume of model}=\text{Volume of 1st building}+\text{Volume of 2nd building}$

$34\text{ in}^3=15\text{ in}^3+\text{Volume of 2nd building}$

$34\text{ in}^3-15\text{ in}^3=15\text{ in}^3-15\text{ in}^3+\text{Volume of 2nd building}$

$19\text{ in}^3=\text{Volume of 2nd building}$

Therefore, the volume of the other building is 19 in.³

How to slove -6≤17+p

goblinko [34]

Hello there!

Answer: ⇒⇒⇒⇒⇒ $p\geq-23$

__________________________________________________________________

Step-by-step explanation:

First you had to switch sides.

$17+p\geq-6$

Then you subtract by 17 from both sides of equation.

$17+p-17\geq-6-17$

Simplify it should be the correct answer.

$p\geq-23$

I need help PLEASE I have to factor the examples and I also need to show my steps I forgot how to do it can somebody plz help!!

Zina [86]

For this, all you need to do is factor out the GCF, or greatest common factor. To find the GCF of these terms, list the factors of each term and the greatest one they share is their GCF. In this case, the GCF is 5x. Factor out 5x from this expression, and your answer is going to be $5x(2x-5)$
