Question 1:
For this case we must rewrite the following equation:
If we add 3x to both sides of the equation we have:
Thus, we have that an equivalent expression is option C.
Answer:
Option C
Question 2:
For this case we must solve the following equation:
Subtracting 5 from both sides of the equation we have:
Dividing between -5 on both sides of the equation we have:
Answer:
Option B

Answer:
The sum of the first 37 terms of the arithmetic sequence is 2997.
Step-by-step explanation:
Arithmetic sequence concepts:
The general rule of an arithmetic sequence is the following:
In which d is the common diference between each term.
We can expand the general equation to find the nth term from the first, by the following equation:
The sum of the first n terms of an arithmetic sequence is given by:
In this question:
We want the sum of the first 37 terms, so we have to find
Then
The sum of the first 37 terms of the arithmetic sequence is 2997.
Answer:
C) 6
Step-by-step explanation:
Given: b(X) = l x + 4 l
Now plug x = -10 in the given function, we get
b(-10) = l -10 + 4 l
b(-10) = l -6 l
The given function is an absolute function, the absolve value is always positive.
The absolute value is nothing but distance from the origin. The distance cannot be negative. Therefore, the absolute value is always positive.
Therefore, b(-10) = 6
Answer: C) 6
Hope you will understand the concept.
Thank you.
