Anastasia was trying to decide which investment plan would be best over 10 years. bank a was offering 8.5% simple interest on her money using the formula i=prt bank b was offering 8% compounded annually using the formula a=p(1+r)^t. which bank is a better investment if she has $2,000 to invest for 10 years?

a. bank a is the better investment. in 10 years, her $2,000 will grow to $4,317.85, and with bank b, her $2,000 will grow to $3,700.

b. bank b is the better investment. in 10 years, her $2,000 will grow to $4,317.85, and with bank a, her $2,000 will grow to $3,600.

c. bank a is the better investment. in 10 years, her $2,000 will grow to $4,521.97, and with bank a, her $2,000 will grow to $3,700.

d. bank b is the better investment. in 10 years, her $2,000 will grow to $4,317.85, and with bank a, her $2,000 will grow to $3,700.

D

Step-by-step explanation:

Bank B is the better investment. In 10 years, her $2,000 will grow to $4,317.85, and with bank A, her $2,000 will grow to $3,700

(0,-3) see attached graph

step-by-step explanation:

a. to solve the system, graph the two equations.

x = y+3 becomes y=x-3 has m=1/1 and b=-3. start at (0,-3) on the y-axis and plot a point. then move up 1 unit and 1 unit to the right. plot a point and connect.

y=-4x+3 has m =-4/1 and b=-3. start at (0,-3) on the y-axis and plot a point. then move down four units and to the right 1 unit. plot a point and connect.

the solution is the point (x,y) where the two lines intersect. by the graph below it is (0,-3).

b. to solve by substitution, substitute y = -4x-3 into x= y+3

x= (-4x-3) +3

x=-4x

5x=0

x=0

now substitute x = 0 back in to find y.

y= -4(0)-3

y=0-3

y=-3

solution is (0,-3)

c. use elimination by adding the equations together.

x-y=3

4x+y=-3

5x=0

x=0

then substitute into one equation to find y.

y=-4(0)-3

y=-3

1/4 because there is 4 grades.
