The linear model y equal 0.6 x plus 45 represents the number of pairs of sandals sold, y, for a given outdoor temperature of x degrees at a certain shoe store. How many pairs of sandals should the company expect to sell if the outside temperature is 90 degrees?

99

Step-by-step explanation:

Given the linear equation:

y = 0.6x + 45

x = outdoor temping degrees ; y = number of pair of sandal sold

Number of pairs of sandals the company expect to sell if the outside temperature is 90 degrees?

y = 0.6(90) + 45

y = 54 + 45

y = 99

The expected number of sandals to sale will be 99

the first one is x^2+2x+2

the second one is x^2+4

the last one is x^2-4x+8
