Observe the equation below, can a value be found for x to make the equation true? Why or why not? 0=4x
Fiesta28 [93]
You have written 0 = 4x.

The value of x that makes it true is x = 0, given that 4 times 0 is 0.

Nevertheless, I think you wanted to write 0 = 4 ^x (this is 4 raised to the power 4).

In that case, there is not any valued of x that satisfies the equation. This is, the equation is always false.

That is because, there is not any value of x for which 4^x is zero. The range of this function is al the positive values of x, which exclude zero.

How do I work out this
Ivenika [448]

Answer & Step-by-step explanation:

1.5 litres = 1500ml

<u>Small Milk Carton</u>

300ml x 5 = 1500ml

£1.20 x 5 = £6

<u>Large Milk Carton</u>

500ml x 3 = 1500ml

£1.40 x 3 = £4.20

The best value for 1.5l (1500ml) is to purchase 3 large milk cartons, as it's cheaper (by £1.80) than buying a small milk cartons.
