Answer:
Assume you will invest fixed amount x at the starting of each month
S(12): (1.00625x)*(1.00625^(12)-1)/(1.00625-1) = 2000
x=160
you will invest fixed amount 160 at the starting of each month and get 2000 at the end of the year ,which compounded 7.5% monthly.
how much will you have invested at the end of the first year ?
160*12=1920
-4 + -7= -11
When adding negative numbers if the are both negative then you add them. When you have a negative and a positive you subtract. In this problem they just took out the plus sign.
Answer: 12.4 + 1.1x + 2.2x^2 + 2.3x^3
Step-by-step explanation:
add the like variables
F(x)=-2x+4x-7
f(x)=2x-7
now f(-4)=2(-4)-7=-8-7=-15
So it will be -15
