Answer 1

Answer: 4.
seems to be a geometric sequence
common ratio is -4
first erm is -2
$a_(n)=-2(-4)^(n-1)$

5. x=-1
remember x^-1=1/x
f(-1)=4(7^-1)=4(1/7)=4/7
f(2)=4(7^2)=4(49)=196

6. remember
(ab)/(cd)=(a/c)(b/d)
also
(x^m)/(x^n)=x^(m-n)
and
(x^m)(x^n)=x^(m+n)

so
$(4.5*10^(3))/(9*10^(7))$ =
( $(4.5)/(9)$ )( $(10^(3))/(10^(7))$ )=
(0.5)( $10^(3-7)$ =
(0.5)(10^-4)=
(5)(10^-1)(10^-4)=
(5)(10^(-1-4)
5*10^-5

4. $a_(n)=-2(-4)^(n-1)$

5. f(-1)=4/7
f(2)196

6. 5 times 10^-5

A line has a rise of 3 and a run of 12. What is the slope?

Answers

Answer:

Slope = rise/run =3/12 =1/4

Step-by-step explanation:

Slope is defined as the rate of change of y wrt x.

Rate of change of y is sometimes named as rise and rate of change of x is named as run.

Given that Rate of change of y i.e. rise is 3 and rate of change of x i.e. run is 12.

Hence slope = 3/12 =0.25

the slope is
3
---------
12

Which equation shows the quadratic formula used correctly to solve 7x2 = 9 + x for x?

Answers

For future reference, use a * to show the multiplication sign because in math x is a variable. 7*2 = 9 + x

Now multiply 7*2= 14

14 = 9 + x

Now subtract 9 from both sides to isolate the x

How to write g(x)=2x+3/x+1 in the form of:g(x)=a/x+p +q

Answers

Hello,

Please write correctly.

g(x)= (2x+3)/(x+1) to be written like a/(x+p) + q

It is very simple!

(2x+3)/(x+1)= [(2x+2)+1]/(x+1)= (2(x+1)+1)/(x+1)= 2+1/(x+1)
