2y = 4x - 12 \\ y =  - 2x + 2 \\  \\ 2( - 2x + 2) = 4x - 12 \\  - 4x + 4 = 4x - 12 \\ 4 = 8x - 12 \\ 16 = 8x \\ 2 = x \\  \\ y =  - 2(2) + 2 \\ y =  - 4 + 2 \\ y =  - 2

Solve for x.
Ivanshal [37]

Answer:

x = -3.25

Step-by-step explanation:

2/5 = 0.4

0.4x - 0.2 = -2(3/4)

-2(3/4) = -2/1 * 3/4 = -6/4

0.4x - 0.2 = -6/4

Convert to fraction

2/5x - 1/5 = -6/4

Add 1/5 to both sides

-6/4 + 1/5 = -30/20 + 4/20 = -26/20

2/5x = -26/20

Convert to decimal

0.4x = -1.3

-1.3/0.4 = -3.25

x = -3.25

Nastasia [14]

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
