Solve the equation. Negative StartFraction 9 Over 15 EndFraction y + StartFraction 3 Over 21 EndFraction = StartFraction 5 Over 15 EndFraction y minus StartFraction 14 Over 21 EndFraction

What is the solution?
y = StartFraction 68 Over 315 EndFraction
y = StartFraction 31 Over 105 EndFraction
y = StartFraction 85 Over 98 EndFraction
y = StartFraction 85 Over 28 EndFraction

step-by-step explanation:

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:

-60.75

step-by-step explanation:

just add the numbers then put the negative sign on it
