AlekseyPX

Answer:

y/x = (a + b) / (m + n)

Step-by-step explanation:

-(xb − ym) = -yn + xa

Distribute:

-xb + ym = -yn + xa

Combine like terms:

ym + yn = xa + xb

Factor:

y (m + n) = x (a + b)

Rearrange:

y/x = (a + b) / (m + n)

The air quality index, or aqi, measures how polluted the air is in your city and assigns a number based on the quality of the ai
makkiz [27]

The number of days in which the air quality index exceed 100 in the year 1988 is 75 days. Then the correct option is B.

<h3>What is a function?</h3>

The function is an expression, rule, or law that defines the relationship between one variable to another variable. Functions are ubiquitous in mathematics and are essential for formulating physical relationships.

The air quality index (AQI) is given by the function.

\rm n = 1.76t^2-13.32 +41

Where n be the number of days the AQI exceeds 100 in a given year.

For \rm t = -2, then we have

\rm n = 1.76(-2)^2-13.32(-2) +41\\\\n = 7.04+26.64+41\\\\n = 74.68 \approx 75

More about the function link is given below.
