It would be 4!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
175 just cross multiply and divide
A) The rate of change is -40 songs each week, that is because the amount of songs left to be downloaded decrease by 40 each week
B) lets use 2 points of the graph p1(0, 200), p2(1, 160)
calculate the slope:
m = (y2- y1)/(x2 - x1) = (160 - 200)/(1 - 0)
m = -40
now use line equation in form point-slope:
y - y1 = m(x - x1)
y - 200 = -40(x - 0)
y = -40x + 200
<span>1/10 you can make an equivalent fraction to make 10/100 then you have two numbers with the same denominator then you just add 8+10 which equals 18, therefore, the answer is 18/100 </span>
