Answer:
(7,12),(-12,-7)
Step-by-step explanation:
x^2 + y^2 = 193
x - y = - 5
x = y - 5
(y - 5)^2 + y^2 = 193
y^2 - 10y + 25 + y^2 = 193
2y^2 - 10y + 25 = 193
2y^2 - 10y + 25 - 193 = 0
2y^2 - 10y - 168 = 0
2*(y^2 - 5y - 84) = 0 This factors into
2*( y - 12) (y + 7) = 0
y = 12
in which case x = 12 - 5 = 7
y = - 7
in which case x = -7 - 5 = - 12
Answer:
0.20 - $117.76= $16.62
Step-by-step explanation:
if you have a percentage you can always turn it into a decimal just put the number behind the period: 70% = .70, 49% = .49% ....
then you do the rest of the equation and BOOM!
20% - $117.76 = $16.62 = 0.20 - $117.76= $16.62.
