Step-by-step explanation:

1. Using the addition property of equality, we can add 3 to both sides of the equation. Then it can be rewritten as ...

  7x -3 +3 = -17 +3

  7x = -14

__

2. Using the division property of equality, we can divide both sides of the equation by 7. Then it can be rewritten as ...

  7x/7 = -14/7

  x = -2

Additional comment

Note that we have used these steps to solve the equation, find the value of x that makes it true. We could use different steps to rewrite the equation to almost anything you want:

  7x -3 -95 = -17 -95   ⇒   7x -98 = -112 . . . . . subtract 95 from both sides

  12(7x -98) = 12(-112)   ⇒   84x -1176 = -1344 . . . . multiply both sides by 12

The resulting equation is not helpful for finding a solution, but it is an accurate rewrite of the original equation.

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:
