X= 9 over 4 is the correct answer
45 dogs and 52 cats because 5+7=12 so 45+7=52
Answer:
x = -3 or x = 3
Step-by-step explanation:
Subtract 9 from both sides.
x^2 - 9 = 0
Factor the left side. There is no common factor of the terms. It is a binomial which is the difference of two squares, so it factors into the product of a sum and a difference.
(x + 3)(x - 3) = 0
Set each factor equal to zero.
x + 3 = 0 or x - 3 = 0
Solve each equation.
x = -3 or x = 3
Answer:
The 75th term of the arithmetic sequence -17, -13, -9.... is:
Step-by-step explanation:
Given the sequence
An arithmetic sequence has a constant difference 'd' and is defined by
computing the differences of all the adjacent terms
The difference between all the adjacent terms is the same and equal to
The first element of the sequence is:
now substitute and in the nth term of the sequence
Now, substitute n = 75 in the sequence to determine the 75th sequence
Therefore, the 75th term of the arithmetic sequence -17, -13, -9.... is:
