Answer:
1/2 year
Step-by-step explanation:
Put the numbers into the interest formula and solve for t.
I = Prt
8100 = 180000(0.09)t
t = 8100/16200 = 1/2
It will take 1/2 year to earn N8100 in interest at 9%.
Answer:
y = -3x - 3
Step-by-step explanation:
Going from the point (0,3) to the point (1,0), we see that the rise (change in y) is -3 and the run (change in x) is 1. Thus, the slope of the new line is
m = rise/run = -3/1 = -3.
Using the coordinates of the given point (-1, 0), we'll find the equation of this line in point-slope form:
y - 0 = m(x + 1), or y = -3(x + 1), or (in slope-intercept form) y = -3x - 3
Answer:
The answer is 120, 80, 100, 180, 40, 0, 240
Step-by-step explanation:
In this situation, quadrupling means to times everything (everything which is 30, 20, 25, 45, 10, 0, 60) by 4, which will give you 120, 80 ,100 ,180, 40, 0, 240
