I hope this helps you
25y^2+60y+36-24=0
25y^2+60y+8 =0
disctirminant =60^2-4.25.8
disctirminant =3600-800
disctirminant =2800
x1= -60+square root of 2800/2.25
x1= -60+52.91/50= -7.09/50= -0.14
x2= -60- square root of 2800/2.25
x2= -60-52.91/50
x2= -2.25
Answer:
18
Step-by-step explanation:
you solve x by three to get 61 and divide by 4 to get 18
The equation would be: y = 100(0.7)^x
This is an example of an exponential decay equation. They are in the form of y = ab^x.
A is the starting value.
B is the rate of change. In this case, we are using 0.7 or 70% because the amount is decreasing by 30%. 100% - 30% = 70%
