You cant have a negative exponent

The mistake is in 3rd step, as we can't equate powers if bases are different.
4^-3=2^8a
2^-6=2^8a
-6=8a
-3/4=a

What are the x and y-intercepts of the line described by the equation?<br> -6x + 3y = 18.9

-BARSIC- [3]

Answer:

x-intercept - x = 1/2y - 3.15

y-intercept - y = 2x + 6.3

Step-by-step explanation:

For x,

-6x + 3y = 18.9

-6x = -3y + 18.9

x = -3y/-6 + 18.9/-6

x = 1/2y - 3.15

For y,

-6x + 3y = 18.9

3y = 6x + 18.9

y = 6x/3 + 18.9/3

y = 2x + 6.3

Determine whether the rule represents an exponential function. Explain why or why not.

Alenkasestr [34]

Answer:

Yes.

Step-by-step explanation:

Exponential Parent Function: $f(x)= a(b^{x})$

If we write out the equation:

$y = 6(5)^{x}$

Whenever we have an exponent of <em>x</em>, it is a exponential function. The 5 is simply the base of the exponent and the 6 means we are vertically stretching the graph by a factor of 6.
