It has been estimated that a certain stream can support 96,000 fish if it is pollution-free. It has further been estimated that for each ton of pollutants in the stream, 1100 fewer fish can be supported. Assuming that the relationship is linear, write the equation that gives the population of fish p in terms of the tons of pollutants x

p = 96,000 - 1100x

Step-by-step explanation:

If p (population of fish) is equal to 96,000 therefore P = 96,000

If it is reduced by 1100 for each ton of pollutants (x) then P = 96,000 - 1100x

Each ton is represented by x so for example if 5 tons of pollutants are added to the stream, the population of fish P will be 96,000 - 1100(5) = 90,500. This will also hold true for decimals since it is an estimate for example if 26.5 tons of pollutants are added to the stream, the population of fish P will be 96,000 - 1100(26.5) = 66,850.

answer: option a.

step-by-step explanation:

you know that the quadrilateral opqr ( a four sided figure) is inscribed in circle. this means that all its vertices are on the circle.

then, by definition, the opposite angles of the quadrilateral are supplementary, this means that the sum of their measures is 180 degrees.

you can observe in the figure that the angles ∠opq   and the angle ∠orq   are opposite, therefore:

then, can be used to d to calculate the measure of ∠opq
