Answer:
$2.95
Step-by-step explanation:
$22.95-$20
Assuming you mean
(x-2)²=49
sqare root both sides and take positive and negative roots
x-2=+/-7
add 2 to both sides
x=2+/-7
x=2+7 and 2-7
x=9 and -5
Answer:
maybe "non-included"?
Step-by-step explanation:
Answer:
See the attached figure.
Step-by-step explanation:
The given function is called piecewise function which is the function that can be in pieces, i.e: defined by multiple sub-functions.
So, need to graph 2x in the interval [3,∞)
And graph -(1/3) x + 7 in the interval (-∞,3]
We will find that f(3) at the function 2x will be equal f(3) at the function -(1/3) x + 7
Which mean the function is continuous.
The attached figure represents the graph of function, it was graphed using the tables on the graph.
Answer:
The total number of registered doctors was 167,722.
Step-by-step explanation:
Total number of doctors:
The total number of doctors is given by x.
31.6% of all registered doctors were female. 53,000 female doctors.
This means that:
![0.316x = 53000](https://tex.z-dn.net/?f=0.316x%20%3D%2053000)
What was the total number of registered doctors?
We have to solve the above equation for x. So
![x = \frac{53000}{0.316}](https://tex.z-dn.net/?f=x%20%3D%20%5Cfrac%7B53000%7D%7B0.316%7D)
![x = 167722](https://tex.z-dn.net/?f=x%20%3D%20167722)
The total number of registered doctors was 167,722.
