Adam's favorite online retail store is having a sale: jeans are $17 each and sweaters are $9 each, sales tax included. If Adam purchases at least $75 worth of jeans and sweaters, he will receive free shipping and handling. Let x represent the number of jeans purchased and let y represent the
number of sweaters purchased. Which of the following inequalities represents the number of jeans and sweaters Adam must purchase in order to
receive free shipping and handling?

answer:   x = 3 + √11     and     x = 3 - √11

step-by-step explanation:

x² - 6x + 9 = 11

(x - 3)² = 11

x - 3 = ±√11

    x = 3 ± √11

x = 3 + √11     and     x = 3 - √11

step-by-step explanation:

i found the koficent of the linear function and i foun c acordind to the strict formula y=kx+c and then i took 2 as an x and replacet it on the formula i found and then foun the y

e^-kt = n/n0 = 0.79  

-kt = ln 0.79  

t = - ln 0.79/0.0001  

= 2357 years
