Answer:
(3, 2), (2, 3)
Step-by-step explanation:
x + y = 5
xy = 6
Solve the first equation for x.
x = 5 - y
Substitute 5 - y for x in the second equation.
xy = 6
(5 - y)y = 6
5y - y² = 6
y² - 5y + 6 = 0
Factor.
(y - 2)(y - 3) = 0
y - 2 = 0 or y - 3 = 0
y = 2 or y = 3
Now substitute 2 for y in the first equation and solve for x.
x + y = 5
x + 2 = 5
x = 3
One solution is x = 3; y = 2, or (3, 2).
Now substitute 3 for y in the first equation and solve for x.
x + y = 5
x + 3 = 5
x = 2
Another solution is x = 2; y = 3, or (3, 2).

Answer:
the actual answer is a(n)= 500 * ( 1 + 0.03) ^(n - 1) ;$579.64
Step-by-step explanation:
4y + 228 = 352
4y = 352 - 228
4y = 124

To find the slope, we put this in y = mx + b form where m is ur slope.
3x - 4y = 7.....subtract 3x from both sides
-4y = -3x + 7 ...now we divide both sides by -4
(-4/-4)y = (-3/-4)x + (-7/4)...simplify
y = 3/4x - 7/4
y = mx + b
y = 3/4x - 7/4.....so the number in the m position is 3/4 <== ur slope
$346/100=$3.46 =1% of $346. So, giving 10% discount we $3.46*90=$311.40
Again, $311.40/100=$3.114, providing, 10% discount we get $3.114*90=$280.26.
The net cost after the series discount is $280.26
