Step-by-step explanation:
J(x)=-8x+48
J(5)=-8×5+48
J(5)=-40+48
J(5)=8
Number of revolutions = 4400000/7
= 628571 turns
Answer:
2≤x≤4
Step-by-step explanation:
2 is less than/equal to x; x is less than/equal to 4
For this case we have the following function:
We must find the inverse function. For this we follow the steps below:
Replace c (f) with y:
We exchange variables:
f = \frac {5} {9} (y-32)
We solve for "y":
We multiply byon both sides of the equation:
We add 32 to both sides of the equation:
We change y by
