Math questions, help appreciated. The Pool Fun Company has learned that by pricing a newly released Fun Noodle at $5 sales will reach 7000 Fun Noodles per day during the summer. Raising the price to $6 will cause the sales to fall to 5000 Fun Noodles per day.

Assume that the relationship between sales price, x, and the number of Fun Noodles sold, y, is linear. Write an equation in a slope-intercept form describing this relationship. Use ordered pairs of the form (sales price, number sold).

The equation is?

option a is correct.

step-by-step explanation:

scale factor: it is used to find proportional measurements.

proportions means having the same ratio.

scale factor is the ratio of the model measurement to the actual measurement in a simplest form.

or we can say that the ratio of any two corresponding lengths in two similar geometric figures

if the scale factor is more than 1, then it is an enlargement,

if the scale factor less than 1, then it is a reduction.

given the two geometric figure:

by definition of proportions, we have

60%

m∠5 + m∠3 = m∠1   is true.

m∠5 + m∠6 = 180 is true

m∠2 +m∠3 = m∠6   is true

m∠2 +m∠3 +m∠5 = 180   is true
