If twice a number is at least three less than four times the number, which of the following are true? Let n represent the number
NikAS [45]

Answer:


Step-by-step explanation:

Let n represent the number

Twice the number =2n


4 times the number = 4n


Given that twice the number is atleast 3 less than four times the number


Algebraically this can be written as


2n≤4n-3


We can add 3 to both sides


So n should be atleast 1.5


If n is natural number or integer then least value of n is 2.

G(x) = x3 + 6x2 + 12x + 8<br><br><br><br> Determine the function’s value when x = −1.
salantis [7]

Answer:

g(-1) = 1

Step-by-step explanation:

Synthetic division is by far the fastest way to evaluate this function at x = -1.  Set up synth. div. as follows:

-1   )   1    6    12    8

              -1    -5    -7

     ----------------------

         1     5     7     1                

since the remainder is 1, g(-1) = 1
