Answer:
x = -6
Step-by-step explanation:
The axis of symmetry represents the x - value of a parabola. The axis of symmetry is known as the "peak" of the parabola. The "peak" as in the point in the parabola where you see the direction start to go downwards/upwards again. When using the point of the "peak", your axis of symmetry would only be the x - value.
For example:
The "peak" point is (-6, 6). Your x - coordinate is -6 and your y - coordinate is 6. Since the axis of symmetry only focuses on the x - value, then your axis of symmetry would be x = -6
This is a multiplicative principle's question. Let's think how we can solve that.
If we want numbers are greater than 1000, so we need numbers with 4 digit (for example: 1001, 2350 and so on).
Imagine that we need to complete four spaces: one thousands, hundreds, tens and ones. See below how to compelete each space:
- One thousands: In this space, we can't use the number 0, because in this way, the number will have 3 digits and we want number with 4 digits (for example: 0235 is a 3 digits number). Therefore, we can use the numbers 2, 3 and 5 to complete this space. So, there are 3 possibilities.
- Hundreds: Now, we can use the number 0 and the number won't have 3 digits (for example: 2035 is a 4 digits number). Therefore, we can use the numbers 0, 2, 3 and 5 to complete this space. So, there are 4 possibililities.
- Tens: Ih this case, it happens the same thing that happen in the case of hundreds. Therefore, there are 4 possibilites.
- Ones: Finally, in this case it also happens the same thing that happen in the case os hundreds. So, there are 4 possibilites.
For multiplicative principle, we just need multiply these numbers of possibilities to find the result of this question:
Therefore, we can write 192 numbers using the digits (0, 2, 3 and 5) and all these numbers are greater than 1000.

Step-by-step explanation:
The equation of direct variation is y=kx.
K is the constant of proportionality, which is in this case is -3.
y=-3x
