You saved $1,240 and your sister agrees to put it in a savings account at her credit union so you can earn interest. You earned
leva [86]

The amount after 2 years is $2,295.

Given that,

  • The invested amount is $1,240.
  • The rate of interest is 8%.
  • The number of years is 2 × 4 = 8

Based on the above information, the amount after 2 years is

Future value = Present value ×(1 + rate of interest)^number of years

= $1,240 × (1 + 0.08)^8

= $1,240 × 1.08^8

= $2,295

Therefore we can conclude that the amount after 2 years is $2,295.

Pick 2 pairs of equations t<span>hen use addition and subtraction to eliminate </span>the same variable<span> from both pairs of equations then it is left with 2 variables 
</span>Pick two pairs
<span><span>4x - 3y + z = - 10</span><span>2x + y + 3z = 0
</span></span>eliminate the same variable from each system
<span><span>4x - 3y + z = - 10</span> 
<span>2x + y + 3z = 0</span> 

<span>4x - 3y + z = - 10</span>

Quadrilateral WXYZ is a Parallelogram. Find the value of each variable.
Arisa [49]

Answer: a=3, b=1

A parallelogram have its opposite sides equal and parallel.

Step-by-step explanation:

SO, the quadrilateral WXYZ have its opposite sides equal as its a parallelogram.

From the given figure the side XY= WZ and XW= YZ, which gives two equations i.e

   Equation 1 is    3a-4=a+2       and     Equation 2 is     b+1=2b

Solving Equation 1                                     Solving equation 2

                    3a-a = 2+4                                    2b-b = 1                          

                    2a   =  6                                              b=1

                       a   =  3                    

So, by solving the two equations a=3 and b=1.
