Which shows the equation in standard form? 7 - 3 ( x -y) = 5x + 2 a. 3x - 8y = 5 b. 8x + 3y = 5 c. 8x - 3y = 5 d. 8x - 3y = -5

C. 8x - 3y = 5

Step-by-step explanation:

7 - 3(x - y) = 5x + 2

7 - 3x + 3y = 5x + 2

7 - 3x + 3y = 5x + 2

-2 + 3x+ 3x - 2

5 + 3y = 8x

- 3y - 3y

5 = 8x - 3y >> 8x - 3y = 5

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:
