It is 130 beats per minute.
Step-by-step explanation:
Just divide 1560 by 12.
Gm, it’s almost night for me
Start by representing the lengths of the three sides of your triangle:
first side: x-4 (inches)
second side: x (inches)
third side: (x-4) + 3 (inches)
Add these three quantities up to obtain a formula for the perimeter, and set your sum equal to the given perimeter (15 inches):
x-4 + x + x-4 -3 = 15
3x-11=15
3x=26
x=26/3
Thus, the length of the 2nd side is 26/3; that of the first side is 26/3-4, or 14/3; and that of the third side is 14/3+3, or 23/3 (all measurements in inches).
You must multiply 5x-3 with 5, then you will get
25x-15 = 1
25x = 1+15
25x = 16

x = 0.64
B) can be rewritten in function notation.
To find the function we must isolate y. To do this, we must subtract x from each side which will give us 
Now, we can replace y with f(x), so the function is
