First, let's put the second equation, <span>x-2.23y+10.34=0, in terms of y:
x - 2.23y +10.34 = 0
2.23y = x + 10.34
y = .45x + 4.64
Now we can substitute the right side of this equation for y in the first equation
</span><span>y=2x^2+8x
.45x + 4.64 = 2x^2 + 8x
Turn it into a quadratic by getting 0 on one side:
2x^2 + 8x - .45x - 4.64 = 0
2x^2 + 7.55x - 4.64 = 0 Divide both sides by 2
x^2 + 3.76x - 2.32 = 0
x =( -b +/- </span>√(b² - 4ac) ) / 2a
x =( -3.76 +/- √(14.14 + 9.28)) ÷ 2
x = .54 or -4.31
Plug the x values into y = .45x + 4.64
y = .45 (.54) + 4.64
y = 4.88 when x= .54
y = .45 (-4.31) + 4.64
y = 2.70 when x= -4.31
Solution set:
{ (0.54, 4.88) , (-4.31, 2.70) }
In Five month Jay should have $15,000 in his account has emergency fund
<h3>Given Data</h3>
Earnings per month = $4000
Monthly Expenses = $3000
Monthly Rent = $2000 part of monthly expenses
After deducting monthly expenses from Monthly earning we have
4000-3000 = $1000
<h3>Determining the 5-months Emergency Funds</h3>
Since we have a monthly expenses of $3000 a five month emergency fund will be
= 3000*5
= $15,000
