Answer: .
Step-by-step explanation:
It is given that three times a number r plus 8 is fewer than −12.
We need to write the sentence as an inequality.
Three times a number r = 3r
Times a number r plus 8 = 3r+8
Fewer than = less than = <
So, the inequality for the sentence "three times a number r plus 8 is fewer than −12" is
Therefore, the required inequality is .
The approximate solutions of the equation are x = -0.93358695, and 1.05794841.
Given
Consider the equation .
Change of base formula is used in the evaluation of log and has another base than 10.
Taking log base 5 on both sides;
Then,
The solution of the equation is;
The solution is by graphing x + 5 and 5^(x^2) as two separate functions and then reading off the approximate x-coordinate of the point of intersection.
The solution is the x-value of the point of intersection.
x= -0.93358695, 1.05794841
Hence, the approximate solutions of the equation are x = -0.93358695, and 1.05794841.
