Answer:

x = 4

y = -7

Step-by-step explanation:

y = -2x + 1

4x + y = 9

4x + y = 9

4x + (-2x + 1) = 9

4x - 2x + 1 = 9

2x + 1 = 9

2x = 9 - 1

2x = 8

x = 8/2

<u>x = 4</u>

4x + y = 9

4(4) + y = 9

16 + y = 9

y = 9 - 16

<u>y = -7</u>

Challenge You have 2 different savings accounts. For Account A, the simple interest earned after 3 months is $1.60. For Account
const2013 [10]

Answer:

$1.28

Note for you:

I hope this helps!

Answer and Step-by-step explanation:

The computation is shown below;

As we know that

The simple interest is

Simple interest = Principal × rate × time

For Account A, the principal would be

2 = Principal × 3.2% × 3

So, the principal is $20.83

For account B, the principal would be

38.50 = Principal × 2.2% × 30

So, the principal is $58.33

Now the interest for both the accounts are as follows

For account 1

= $20.83 × 3.2%

= $0.67

And, for the account 2

= $58.33 × 2.2%

= $1.28

As it can be seen that the account 2 has the highest interest

The same is to be considered
