Answer:
Step-by-step explanation:
Given:
Required
Rewrite in vertex form
The vertex form of an equation is in form of:
Solving:
Subtract 2 from both sides
Factorize expression on the right hand side by dividing through by the coefficient of x²
Get a perfect square of coefficient of x; then add to both sides
------------------------------------------------------------------------------------
<em>Rough work</em>
The coefficient of x is
It's square is
Adding inside the bracket of to give:
To balance the equation, the same expression must be added to the other side of the equation;
Equivalent expression is:
------------------------------------------------------------------------------------
The expression becomes
Factorize the expression on the right hand side
Make y the subject of formula
<em>Solved</em>
1. Y = 10x
2. Y = 100 + 30x
3. Y = 50 + 1x
5. Y = 15 + .12x
Answer:
7000 in the account that paid 9% interest rate and 3000 in the account that paid 8% interest rate
Step-by-step explanation:
Let $x be invested in account 1 and $(10000-x) in the second account
Then, 870=x*9/100+(10000-x)*8/100
x=$7,000.
