Answer:

a8 = 512.

Step-by-step explanation:

This is geometric sequence with common ratio r = 2 and first term a1 = 4.

nth term = a1 r^(n-1)

So a8 = 4 2(^8-1)

= 4 * 2^7

= 4*128 = 512.

Can x=9.4 be written in y=mx+b form?

Westkost [7]

Answer:

The given equation cannot be written in slope intercept form

Step-by-step explanation:

we know that

$y=mx+b$

Is the equation of the line in slope intercept form

where

m is the slope

b is the y-intercept

In this problem we have

$x=9.4$

This is a vertical line (parallel to the y-axis)

The slope is undefined

therefore

The given equation cannot be written in slope intercept form
