Hello,

f(1)=160
f(2)=160*(-2)
f(3)=160*(-2)²
f(4)=160*(-2)^3=-1280

f(n)=160*(-2)^(n-1)

Please help if you could
Goshia [24]

Answer:

f(x)= 6x+9....

Step-by-step explanation:

The given equation is:

y-6x-9=0

Add 6x+9 at both sides:

y-6x-9+6x+9=0+6x+9

Solve the like terms:

on the L.H.S -6x will be cancelled out by +6x and -9 will be cancelled out by +9

y=6x+9

Now convert it in function notation:

f(x)=y

f(x)= 6x+9....

A gardener has a container with 6 1/5 ounces of liquid plant fertilizer on Sunday the gardener uses 2 1/2 ounces on a flower gar
sergey [27]
Amount of liquid plant fertilizer in the container that the gardener has = 6 1/5 pounds
                                                                                                               = 31/5 pounds
We already know that 1 pound = 16 ounce
Then
Amount of liquid plant fertilizer in the
container that the gardener has = (31/5) * 16 ounce
                                                    = 496/5 pounds                                                          
Amount of liquid plant fertilizer that the gardener uses on Sunday = 2 1/2 ounces
                                                                                                         = 5/2 ounces
Then
The amount of liquid plant fertilizer that are left= (496/5) - (5/2) ounces
                                                                           = (992 - 25)/10 ounces
                                                                           = 967/10 ounces
                                                                           = 96.7 ounces
So the total amount of liquid plant fertilizer left is 96.7 ounces.
