First, distribute the left side. You should get 4x-8-2x+4=4x-8. Then, get all the xs on one side.
4x-2x-4x-8+4=-8
Then, put the numbers on one side.
4x-2x-4x=-8+8-4
Then, add it up.
-2x=-4
Then, solve for x.
(-2x)/(-2)=(-4)/(-2)
x=2
Hope that helps!
Answer: g is a geometric sequence.
Step-by-step explanation:
Each year since then, her account accumulated interest amounting to
15% of the balance in the previous year.
15% = 15/100 = 0.15
Since the balance is increasing each year, then the constant factor by which it is increasing is 1 + 0.15 = 1.15.
This factor of 1.15 is a common ratio. This means that the sequence is a geometric sequence since it is increasing by a common ratio.
Changing the coefficient of x to 6 changes the meaning of the expression as 5 is added to 6 times x
Solution:
Given that number 2 in the expression 5 + 2x is called the coefficient of x
We are asked to find what happens when changing the coefficient to 6 changes the meaning of the expression
In the expression,
5 + 2x
This means 5 is added to 2 times x or 5 is added to twice of x
Number 2 is called the coefficient of x
When we change this coefficient to 6, the expression becomes,
5 + 6x
So now the meaning of expression becomes,
5 is added to 6 times x
So changing the coefficient of x changes the meaning of the expression
SOLUTION
Given the question in the image, the following are the solution steps to answer the question.
STEP 1: Write the given function
