Jacobi wants to solve the system of equations below by using elimination. So far he
has lined up the equations as shown below. Which of the following describes the
next step Jacobi should take?
8x – 2y = -6
- 3x + y =4

Multiply each term in the 1st equation by -1

Multiply each term in the 2nd equation by -2

Multiply each term in the 2nd equation by 2

Add the two equations together

the answer is 200

step-by-step explanation:

the way the question is worded, it seems to imply the $264 interest is simple interest, not compound interest.

the simple interest for 2 years is $264; the simple interest for 1 year is $132.

$132 interest on a $600 investment means an interest rate of (132/600)*100 = 22%.

the value of $200 at 22% interest compounded annually for three years is

200%281.22%29%5e3

the amount of interest is that value, minus the original $200.

i think the answer is true

step-by-step explanation:

46

step-by-step explanation:

given

height = 168 cm

formula

height =2.47*f+54.13

solution

168 = 2.47f + 54.13             subtract 54.13 from both sides

168 - 54.13   = 2.47f             combine

113.87 = 2.47f                     divide by 2.47

113.87 / 2.47 = f                   combine

46.1 = f  

answer: 46 cm
