Round off 9999 yo the nearest 10,100,1000​

10,000

Step-by-step explanation:

10000, 10000, 10000

Step-by-step explanation:

When rounding, we just need to look at the first digit after the "rounding to" digit.

As follows: we adjust the bold digit according to the underlined digit.

In the first case, we need to round the last 9999 - so we round it up.

In the second case, we need to round 9999 - so we round it up.

In the third case, we need to round 9999 - we round up yet again.

so firstly, we need to isolate the y variables to be able to solve these inequalities. firstly, add 0.5x on both sides of the first inequality and subtract 1.5x on both sides of the second inequality:

now since the slope is positive for the first inequality, this means that the line going upwards belongs to the first inequality, and the line going downwards belongs to the second inequality.

next, since y ≥ in the first inequality, this means that the shaded region will be above the first inequality's line, thus shading regions a and b.

next, since y ≤ in the second inequality, this means that the shaded region is going to be below this line, thus shading regions a and c.

since both lines shade region a, this means that region a is the solution.
