For this case what we have to take into account is the following variable:
x = represent the unknown number
We now write the following inequality:
"four times the sum of number and 15 is at least 20"
4 (x + 15)> = 20
We clear the value of x:
(x + 15)> = 20/4
(x + 15)> = 5
x> = 5 - 15
x> = - 10
The solution set is:
[-10, inf)
Answer:
all possible values for X are:
[-10, inf)
Answer:
the answer is essentially d
The area of a circle is given by the formula:
A =

r^2
Since

= 3.14, and r = 6, sub these values into the equation,
A = 3.14 x 6^2
= 113.04
Hope this helped!
Answer:
Log x = 3 is the same as Log into base 10 of 3
Recall from Law of Logarithm: if Log a = x , then a = 10^ x
therefore If Log x = 3 , then x = 10^3 = 1000
