Answer:
X=5
Step-by-step explanation:
3x-8=7
3x=15 (add 8 to both sides)
X=5 (divide by 3)
Answer: The answer to your first question would be A. 1. This is simply because anything raised to the power of 0 is 1 no matter what. The answer to your second question would be B. 1, for the same reason as above, anything to the power of 0 is 1. Hope this helped and make sure to remember that rule, it is important and easy to remember!
The expression that describes all of the values for which the graph is positive and decreasing is all real values of x where x < -1
<h3>Which describes all of the values for which the graph is positive and decreasing?</h3>
The equation of the function is given as:
f(x) = (x - 3)(x + 1)
When the value of the graph is positive, we have:
f(x) > 0
So, the function becomes
(x - 3)(x + 1) > 0
Split the above inequality
x - 3 > 0 and x + 1 > 0
Solve for x in the inequalities
x > 3 and x > -1
Hence, the expression that describes all of the values for which the graph is positive and decreasing is all real values of x where x < -1
