Answer:
x = 1.5; 20x + 5 = 35; 24x + 1 = 37;
Step-by-step explanation:
______________________________
1) 20x + 5 = 24x - 1
2) 20x + 6 = 24x
3) 6 = 4x
4) x = 1.5
_______________________________
20x + 5
1) 20(1.5) + 5
2) 30 + 5
3) 35
_______________________________
24x + 1
1) 24(1.5) + 1
2) 36 + 1
3) 37
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
Answer:
220 I'm pretty sure because 6×5 is 30 times 2 is 60. Then do 6×10 equals 60. Then do 5 times 10 times 2 to get 100. Then you add it all up to get 220
Answer:
x = 0, 1, -4
Step-by-step explanation:
You can look at the graph where the equation intersects the x-axis.
