Answer:
You add the powers, so (X^3)(x^-17)=x^n n= (3+-17) Meaning n=-14
Step-by-step explanation:
There are 3 feet in a yard, this means we must mutlpie 14 by 3.
14 by 3 is 42.
There are 42 feet in 14 yards.
The other person's answer is incorrect.
I Hope This Helps !! And Good Luck On Your Assignment
$25.3. 15% of $22 is 3.3, so plus that to $22, and you get $25.3
Answer:
Step-by-step explanation:
The temperature at a given altitude is
y = 36 - 3x
The temperature on the surface of the planet is the point (0,t) where t is the temperature for the given height.
y = 36 - 3*0
y = 36
So at the surface of the planet is 36 degrees C.
======================
Effectively it is the slope of the equation which is - 3
So ever km going up will mean a loss of 3 degrees. I think they want you to write -3
Answer:
t = -d/50 + 2
0.5 hour
Step-by-step explanation:
Given the equation:
d = 50 - 100t
The inverse function:
A.) solving for t
d = 100 - 50t
d - 100 = - 50t
Divide both sides by - 50
d/-50 - (100/-50) = - 50t/-50
-d/50 - (-2) = t
t = -d/50 + 2
B) using the inverse function:
t = -d/50 + 2
Miles driven (d) = 75, find time (t)
t = - 75/50 + 2
t = - 1.5 + 2
t = 0.5
t is in hours, therefore time left to travel is 0.5 hours or 30 minutes
