It is simplified.
Step-by-step explanation:
Well, r^-7 is bassically 1/r^7
same thing for s
s is bassically 1/s^12
So 1/s^12 + 1/r^7
Answer:
Number of Model A press = 9 and Number of Model B press = 5
Step-by-step explanation:
Number of books Model A can print per day = 70
Number of books Model B can print per day = 55
Let x be the number of Model A press and y be that of Model B press.
Total number of printing presses = 14
x + y = 14 ----------------1
Total number of books printed per day = 905
70x + 55y = 905-------2
Putting y = 14 - x in equation 2, we get:
70x + 55(14 - x) = 905
15x = 135
x = 9
y = 14 - 9 = 5
Hence number of Model A press is 9 and that of Model B press is 5.
Answer:
The slope is 1.
Step-by-step explanation:
A first order function has the following format
In which a is the slope
(6, -12).
This means that when 
So
(15. -3)
This means that when 
So
We have to solve the following system of equations:
We have to find a
In the second equation i will write as:
Replacing in the first
The slope is 1.
7% of 650
= 7/100 * 650
= 0.07 * 650
= 45.5
$45.5
