What is 6x^3 - z ?

x= -8
and
z= 9

FYI the 3 is an exponent on 6x

-110601

Step-by-step explanation:

All you have to do is replace the variables with their value. So the equation would look like this,

6(-8)³ - 9

Always solve the parenthesis first ending up with

-48³ - 9

Now the exponents,

-110592 -9

Here we just subtracting getting the answer of...

-110601

Hope that helps and have a great day!

it could 14.28 but if its not that one then it has to be the 17 one. hope this ! : )

step-by-step explanation:

y = 2x

step-by-step explanation:

if you divide each number in the sequence, you'll see that they all have a multiple factor of 2. each number in the series, and any other numbers which may continue, will be multiplied by 2. therefore, y is the next number in the sequence, and x is the current one, so, our formula will be y = 2x.
