I believe the correct answer from the choices listed above is the third option. The exercise best illustrates Medium of exchange and portability <span>function and characteristic of money. </span>
Hope this answers the question. Have a nice day.
1.B
2.e
3.8+10(x+3)+x
8+10x+30+x
11x=-30-8
x=38+11x
Answer:
(-4,0) and (5,0)
Step-by-step explanation:
Factor.
f(x) = x^2 -x - 20
Factors of -20 that when are added they equal -1
-5 and 4
(x-5) (x+4)
x=5 and x=-4
The right system of equations to describe the situation would
be on the form:
x1 = 8000 + y1*t
and
x2 = 8000 + y2*t
where x1 and x2 represents the total money of Imogene and her
friend respectively at the end of t years.
Now for the value of amount earned, y1 and y2:
y1=8000*0.08
y2=2000*√(t-2)

A is 40
B is 50
C is 115
Explanation, A is the same as the opposite, A + B + 90 = 180, and C + 65 = 180
