Y = 4x<br> y=19 - x<br> Solve the system of equations
sergey [27]

Answer:

x = 3.8

y = 15.2

Step-by-step explanation:

y = 4x

y = 19 - x,

if y = y then,

4x = 19 - x

5x = 19

x = 19/5 = 3.8 now inputting the answer to x into one of the unchanged equations above (y = 4x),

y = 4x = 4*3.8 = 15.2

Double check:

y = 19 - x = 19 - 3.8 = 15.2

With a principal investment of $19,200, which account will have the greatest value after 5 years? simple interest: I = P • r • t
grin007 [14]
Given:
Principal: 19,200
term: 5 years

a) Interest compounded annually:
A = 19,200 (1 + 0.036)^5
A = 19,200 (1.036)^5
A = 19,200 (1.1934)
A = 22,913.28

b) Simple Interest
I = 19,200 * 0.038 * 5
I = 3,648.38

19,200 + 3,648.38 = 22,848.38

c) Interest compounded annually
A = 19,200 (1 + 0.034)^5
A = 19,200 (1.034)^5
A = 19,200 (1.182)
A = 22,694.40

d) Interest compounded quarterly
A = 19,200 (1 + 0.032/4)^4*5
A = 19,200 (1 + 0.008)^20
A = 19,200 (1.008)^20
A = 19,200 (1.173)
A = 22,521.60
