m: y=-2x+4

slope: 2

2/1=2

Its negative because the line is going down from left to right

y-intercept:

it crosses the y axis at (0,4)

n: y=x-1

slope: 1

1/1=1

Its positive because the line is going up from left to right

y-intercept:

it crosses the y axis at (0,-1)

l: y=4

slope: 0

A vertical line's slope is always 0

y-intercept:

it crosses the y axis at (0,4)

p: x=-4

To find the equation for a horizontal line, you need to find what x always is no matter what.

What is f(5) if f(1)=3.5 and f(x+1)=5\2 f(x)

katen-ka-za [31]

Answer:

f(5) = 136.71875‬

Step-by-step explanation:

f(5) if f(1)=3.5 and f(x+1)=5\2 f(x)

f(2) = (5/2)* f(1) = (5/2)* 3.5 = 8.75

f(3) = (5/3)*f(2) =(5/2) * 8.75

f(4) = (5/3)*f(3) =(5/2)*(5/2) * 8.75

f(5) = (5/3)*f(4) = (5/3)*(5/2)*(5/2) * 8.75

f(5) = (5/2)^4 * 3.5 = (625/16) * 3.5 = 136.71875‬

f(5) = 136.71875‬

An arithmetic sequence is given below.

Mashcka [7]

Given that $a_1=24$ and $a_2=17$ , if $a_n$ is an arithmetic sequence, then the common difference between successive terms is $d=a_2-a_1=17-24=-7$ .

You then have

$a_2=a_1+d$
$\implies a_3=a_2+d=a_1+2d$
$\implies a_4=a_3+d=a_1+3d$
$\implies \cdots\implies a_n=a_{n-1}+d=\cdots=a_1+(n-1)d$

So the explicit formula for the $n$ th term is

$a_n=24-7(n-1)$
