Answer:
OR
Step-by-step explanation:
Let's first simplify .
5 and 15 multiply to get 75. 5 and 3 multiply to get 15. Since we have a pair of fives and a three leftover, we can write as:
Now, let's find the answer in decimal form. We know that:
and
With that information, we know that the answer has to be between 8 and 9.
Divide 75 by 8:
Take the average of that answer and 8:
This answer we got is extremely close to the exact answer of , which is . Since we are estimating, the answer above will do just fine.
11H=C. The independent variable is how much she gets paid an hour
The correct statement regarding the quadratic function f(x) = (x - 4)(x + 1) is given by:
It is increasing for x < -1 and x > 4.
<h3>When a quadratic function is increasing and when it is decreasing?</h3>
Considering a concave up quadratic function, with positive leading coefficient, we have that:
- It is increasing to the left of the lower root and to the right of the upper root.
- It is decreasing between the roots.
In this problem, the function is given by:
f(x) = (x - 4)(x + 1).
The roots are:
Hence the correct statement is:
It is increasing for x < -1 and x > 4.
