Answer: (f-g)(x) is equivalent to f(x) - g(x)
So that would be (2x²-5) - (x²-4x-8) = 2x² - x² + 4x + 8 - 5 = x² + 4x + 3
Hope this helps.
15/30 brushed their teeth more than twice a day.
Fraction 1/2 <- (Simply by dividing by HCF)
Percentage= 50% (15 divided by 30 multiplied by 100) or you realise the 15 is half of 30. A half is 50%
Decimal= 0.5 (50% divided by 100)
use the midpoint formula. It's x1 + x2 / 2, y1+y2/2. When you solve you get (0, 1/2) is the midpoint. Hope this helps
