7. One micrometer is a millionth of a meter. A certain spider web is 4 micrometers thic A fiber in a shirt is 1 hundred-thousandth of a meter thick.
a. Which is wider, the spider web or the fiber? Explain your reasoning.
How many meters wider

step-by-step explanation:

what grade level is this? need to know so i can look in my old textbooks!

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.
