Answer:

Y=2x-1

Step-by-step explanation:

In order to find the slope, its rise over run. So you would move from (0,-1) to the next point it intercepts, (1,1) and find it from there

As for the Y-Intercept, it would just be wherever the line connects with the Y axis, which happens to be (0,-1) or Negative 1.

J. Reexamine the sequence 20, 14, 8, 2, ... from the problem

DENIUS [597]

Answer:

The n th of the given sequence is $t_{n} = 26-6 n$

Step-by-step explanation:

Step 1 :-

Given sequence is 20,14,8,2,.......this sequence in arithmetic progression but this sequence is decreasing sequence.

given first term is 20 and difference is $d = second term- first term = 14-20=-6$

now the nth term of given sequence is

by using formula $t_{n}=a+(n-1)d$

$t_{n}= 20+(n-1)(-6)$

$t_{n}= 20-6 n+6$

final answer:-

$t_{n} = 26-6 n$

verification:-

$t_{n} = 26-6 n$

put n=1 we get first term is 20

put n=2 we get second term is 14

put n=3 we get third term is 8

put n=4 we get fourth term is 2

so the n th term of sequence is

$t_{n} = 26-6 n$

If f(x)=2x+3 and g(x)=x^2+1 find f(g(3)) Help!! A.23 B.47 C.82 D.90

True [87]

Answer

A. 23

step-by-step explanation

$g(x) = {x}^{2} + 1$

We put x=3 into the function g

$\implies g(3)= {3}^{2} + 1$

$\implies \: g(3)=10$

Also,

$f(x)=2x +3$

we substitute the value of g(3) into f

$\implies f(g(3))=f(10)$

$\implies f(g(3))=f(10) = 2(10) + 3$

$\implies f(g(3))=23$
