Hi Timothy,

1. Write a rule for the sequence.

8, -1, -10, -19...

A. Start with 8 and add -9 repeatedly

B. star with -9 and add 8 repeatedly

C. start with 8 and add 9 repeatedly

D. start with 8 and subtract -9 repeatedly---

Answer - So you have to start with -9 then keep subtracting 9. Thats what I think the answer is but the answer is not stated in the question. Let me know on what that is. The closest answer is probably either B or D.

2. find the next three terms of the sequence.

-6, -24, -96, -384

1) -768, -1536 , -3072

2) -768, -3072, -12288

3) -1536, -6144 , -24567

4) -1536, -9216, -36864

The rule is multiplying by 4!

So the correct answer is 3) -1536, -6144 , -24567

Consider the function f(x) = the quantity x squared minus x minus 12 all over the quantity x plus 3. Describe the graph of this

FromTheMoon [43]

Answer:

The graph of f(x) is discontinuous at x= -3. The x and y-intercepts or he function f(x) are (4,0) and (0,-4) respectively. The graph of the function is a straight line.

Step-by-step explanation:

The given function is

$f(x)=\frac{x^2-x-12}{x+3}$

$f(x)=\frac{x^2-4x+3x-12}{x+3}$

$f(x)=\frac{x(x-4)+3(x-4)}{x+3}$

$f(x)=\frac{(x-4)(x+3)}{x+3}$

Cancel out the common factor (x+3).

$f(x)=x-4$

It is a linear equation and it will give a straight line.

Put x=0, to find the y-intercept.

$f(x)=0-4$

$f(x)=-4$

Therefore the y-intercept is (0,-4).

Put x=0, to find the x-intercept.

$0=x-4$

$4=x$

Therefore the x-intercept is (4,0).

At x= -3 the value of denominator is 0, therefore the function is undefined for x= -3.

As x approaches toward x=-3 from left and right, the value of function approaches towards y=-7.

The function is discontinuous at x= -3.

Evaluate [(-5+1)÷2]3-|-7|

lakkis [162]

The answer would be -6 because -5+1 =-4 then once you divide it by 2 you get -2 then you do the next part 3-7 because since it’s in those lines that means you get rid of the negative so you would get -4 so the equation should look like this by now -2-4 then solve and you get -6 hope this helped :)
