|a| = a for a ≥ 0
examples
|2| = 2, |4| = 4, |234| = 234, |1/2| = 1/2, |0| = 0
|a| = -a for a < 0
examples
|-4| = -(-4) = 4, |-6| = -(-6), |-123| = 123, |-4/5| = 4/5
|5 - 15| = | - 10| = 10
0 × |-6| = 0
As your question is stated, there is no answer!
I'm going to assume the polynomial you meant is:
To create a perfect square trinomial, take half the coefficient of x and then square it.
In all problems like this, you want to square half the coefficient of x -- always half.
Hi there! The domain of a function refers to the values that can be validly input for x. In laymen's terms, domain is the x-values that exist on a graph of the equation.
If we were to plug in y=-2x+5 into a calculator that shows an infinite graph, we would see that the line of the equation would extend both ways infinitely! This means that all real numbers can be inputs for x, because for every x value that exists there is a corresponding y value.
This means that D. All real numbers, is your answer.
Hope it helps! :)
Answer:
the answer in slope intercept is 15x+60
Answer: 48 quarters or 12 years
Step-by-step explanation:
You can use the Rule of 72 to estimate the amount of time it will take for an investment to double.
It works by dividing 72 by the interest rate per period.
The rate here is 6% but this is an annual rate yet the interest is to be compounded quarterly. You need to convert this annual rate to a quarterly rate:
= 6% / 4
= 1.5% per quarter
The amount of time it will take to double is:
= 72 / 1.5
= 48 quarters
In years that would be:
= 48 / 4
= 12 years
