Which compound inequality is equivalent to lax-b|> c for all real numbers a, b, and c, where c>0?

the correct answers i think are b. and d.

give me brainliest if it is correct!

explanation:

infrared radiation has wavelength in the range between 700 nm and 1 mm. lets' convert these values into scientific notation, keeping in mind that:

let's start from the lower value, we have:

(we moved the dot two places to the left, so we increased the exponent by 2 units, from -9 to -7)

the higher value is:

so, the range of wavelength of infrared radiation is:
