Answer:

the value of a is 4 ÷ 7

Step-by-step explanation:

The computation of the value of a is shown below:

Given that the following equation

|7|x| - 4 = a

Based on the above equation

As we can see that the modulus is applied

So after removing the modulus, it would be

7x - 4 = a

7x = 4

x = 4 ÷ 7

Hence, the value of a is 4 ÷ 7

The same would be relevant

If 1 euro is priced at $1.25 and if 1 euro will also buy 88 Japanese yen (€1 = ¥88), in equilibrium, with no arbitrage opportuni

Alborosie

Answer:

So the exchange rate is that each dollar is worth 70.4 yens.

Step-by-step explanation:

We have that:

1 euro is priced at $1.25

1 euro will also buy 88 Japanese yen

This also means that:

$1.25 is priced at 88 Japanese yen

How much is the cross rate between the yen and the dollar (yen per dollar exchange rate)?

How much yens is 1 dollar?

This can be solved by a simple rule of three.

$1.25 - 88 yen

$1 - x yen

$1.25x = 88$

$x = \frac{88}{1.25}$

$x = 70.4$

So the exchange rate is that each dollar is worth 70.4 yens.

What does the y-coordinate have to be for a point to be on the x-axis?

vesna_86 [32]

Step-by-step explanation:

If we're talking about something like y coordinate being on the x axis, I'd have to say 0. Because it would be on the y axis no matter the coordinates of it isn't a 0. Ex : (0,0) and (0,9). (0,9) would have the point going upwards on the y axis.
