Answer:
y= -21x/19 x≠0
Step-by-step explanation:
(I just reviewed this!) Combined like terms and used Pemdas for Order of Operations. Canceled out -21x with -21 and we know that x is not equal to 0. If you need more help there are some sites like Khan Academy.
Since 10% of $100 so 100(0.10) = 10, they both make an additional deposit of $10. So, they have the same amount of money after the first additional deposit.
After the first additional deposit, Leroi has 1110+ 10 = $120. Sylvia has 110 + 0.10(110) = 110 + 11 = $121. So she has more money after the second deposit.
<u>Sylvia will continue to have more money after a month and a year since 10% of the balance is going to be greater than the $10 deposit that Leroi is making. </u>

- Coordinates (x, y)
- Solving systems of equations using substitution/elimination
Step-by-step explanation:
<u>Step 1: Define Systems</u>
x = -4
5x + 4y = -10
<u>Step 2: Solve for </u><em><u>y</u></em>
<em>Substitution</em>
- Substitute in <em>x</em>: 5(-4) + 4y = -10
- Multiply: -20 + 4y = -10
- [Addition Property of Equality] Add 20 on both sides: 4y = 10
- [Division Property of Equality] Divide 4 on both sides: y = 10/4
- Simplify: y = 5/2
