You deposited $475 into the bank at a 6% interest rate. How much will be in the account after three years
dem82 [27]

Answer:

$565.73 and the interest is $90.73

Step-by-step explanation:

A=475(1+0.061)^1⋅3

A=475⋅1.063

A=475⋅1.191016

A=565.73

To find interest:

A=P+I

565.73II=475+I

I=565.73−475

I=90.73

Solve this pleasee!!!!!!!!!!!
Sholpan [36]

Answer:

1) Solution (2,-3)

2) Solution (-1, -\frac{3}{2})

3) Solution (\mathbf{-\frac{1}{2},-\frac{5}{2}})

Step-by-step explanation:

We need to solve equations using elimination

1) 2x+2y=-2\\3x-2y=12

Let:

2x+2y=-2--eq(1)\\3x-2y=12--eq(2)

Adding both equations:

2x+2y=-2\\3x-2y=12\\--------\\5x=10\\x=\frac{10}{5}\\x=2

We get value of x = 2

Now, put value of x into equation 1 to find value of y

2x+2y=-2\\Put\:x=2\\2(2)+2y=-2\\4+2y=-2\\2y=-2-4\\2y=-6\\y=-6/2\\y=-3

So, we get y = -3

Solution (2,-3)

2) 4x-2y=-1\\-4x+4y=-2

Let:

4x-2y=-1--eq(1)\\-4x+4y=-2--eq(2)

Adding both equations

4x-2y=-1\\-4x+4y=-2\\------\\2y=-3\\y=\frac{-3}{2}

We get: y= -3/2

Now find value of x by putting value of y in eq(1)

4x-2y=-1\\Put\:y=\frac{-3}{2}\\4x-2( \frac{-3}{2})=-1\\4x+3=-1\\4x=-1-3\\4x=-4\\x=\frac{-4}{4}\\x=-1

We get x = -1

Solution (-1, -\frac{3}{2})

3) x-y=2\\x+y=-3

let:

x-y=2--eq(1)\\x+y=-3--eq(2)

Add both equations:

x-y=2\\x+y=-3\\-----\\2x=-1\\x=-\frac{1}{2}

We get x = -1/2

Now, put value of x in equation 2

x+y=-3\\-\frac{1}{2}+y=-3\\y=-3+ \frac{1}{2}\\y=\frac{-6+1}{2}\\y=\frac{-5}{2}

We get y = -5/2

Solution (\mathbf{-\frac{1}{2},-\frac{5}{2}})
