3 0

Answer:

y =(5,0,-3,-4,-3,0,5)

Step-by-step explanation:

To get y you have to replace the different number of x in the equation

For example,

To x=-1

y=x^2-4x

y=(-1)2-4*(-1)=

y=5

to x=0

y=x^2-4x

y=0^2-4*0

y=0

The table will be:

x y

-1 5

0 0

1 -3

2 -4

3 -3

4 0

5 5

Here:

(3,1) becomes (1,3)

(3,1) becomes ((1,3)

(7, -7) becomes (-7,7) and

(12, -15) becomes (-15, 12)

If you multiply a number by 3 and then subtract 5, you will get 40 what is the number

Paul [167]

Answer:

Number = 15.

Step-by-step explanation:

Given : If you multiply a number by 3 and then subtract 5, you will get 40.

To find : what is the number.

Solution : We have given if you multiply a number by 3 and then subtract 5, you will get 40.

According to question :

Let the number = x

Multiply is with 3 = 3x

Subtract 5 from it we get 40 .

3x -5 = 40

On adding both sides by 5

3x = 45 .

On dividing both sides by 3

x = 15.

Therefore, Number = 15.

What does the remainder theorem conclude given that f(x)/x+6 has a remainder of 14? Enter your answer by filling in the boxes.

musickatia [10]

Answer:

$f(-6)=14$

Step-by-step explanation:

According to the remainder theorem, if a function f(x) is divided by (x-a), then the remainder is defined by f(a).

It is given that $\dfrac{f(x)}{x+6}$ has a remainder of 14.

Here, the function f(x) is divided by (x+6). So, on comparing (x+6) and (x-a), we get

$a=-6$

So, by remainder theorem, remainder of $\dfrac{f(x)}{x+6}$ is f(-6).

Since the remainder is 14, therefore

$f(-6)=14$

Therefore, the answer for first blank is -6 and for second blank is 14, i.e., $f(-6)=14$ .
