Answer:

Step-by-step explanation:

The result of adding a number plus the next number will be alternating 4,-4,4,-4,4,-4......

-4+8 = 4

8+ -12=  -4

-12 +16 =4

16+-20=-4

-20 + 24=4

24+-28 = -4

So you need to calculate what number plus the previous number has as result 4 or -4 alternating

8 + ? = -4

?= -4 -8

?=-12

      -12+? =4       ?=12+4     ?=16

16+? =-4     / = -16-4   ?=-20

ANOTHER METHOD

4*-1=-4

4*2=8

4*-3=-12

4*4 = 16

4*-5=-20

4*6=24

4*-7=-28

4*8=32

The cost for x number of gallons of heating oil can be represented by the function f(x)=4x+6 in the context of the problem expla
deff fn [24]

Answer:

This means that the cost of 2 heating oil gallons is 14.

Step-by-step explanation:

f(x) = 4x + 6 , where x is the number of heating oil gallons.

And f(x) = 4x + 6 is the equation for the cost of x gallons.

When the number of gallons are 2 then the cost is;

f(2) = 4(2) + 6 = 8 + 6 = 14

This means that the cost of 2 heating oil gallons is 14.
