Answer:

\large\boxed{f(x)-g(x)-h(x)=-5x^2+6x+6}

Step-by-step explanation:

f(x)=3x+5\\\\g(x)=4x^2-2\\\\h(x)=x^2-3x+1\\\\f(x)-g(x)-h(x)=(3x+5)-(4x^2-2)-(x^2-3x+1)\\\\=3x+5-4x^2-(-2)-x^2-(-3x)-1\\\\=3x+5-4x^2+2-x^2+3x-1\qquad\text{combine like terms}\\\\=(-4x^2-x^2)+(3x+3x)+(5+2-1)\\\\=-5x^2+6x+6

Answer:

- 5x² + 6x + 6

Step-by-step explanation:

f(x) - g(x) - h(x)

= 3x + 5 - (4x² - 2) - (x² - 3x + 1) ← distribute parenthesis

= 3x + 5 - 4x² + 2 - x² + 3x - 1 ← collect like terms

= - 5x² + 6x + 6 ← in standard form

Answer:

x=-1 \ or \ x=-3

Step-by-step explanation:

y = x^2 + 5x +2\\y = x-1\\\\

Equating both equations equal to each other:

x^2 + 5x+2 = x-1\\x^2+5x+2 -x +1 =0\\x^2 + 4x +3 = 0

Breaking the middle term:

x^2 + 4x +3 =0\\x^2 +3x + x +3 =0 \\x(x+3) +1 (x+3) = 0\\(x+1)(x+3)=0\\x+1 =0 \ or \ x+3 =0\\x=-1 \ or \ x=-3

If there were 300 accidents in 1967 and 380 in 1968, what is the percent increase?
VikaD [51]
First find the amount of increase: 380-300=80. Then divide the amount of increase by the original amount: 80/300=.266666667. Normally you round to the tenths place: .27. Then make it a percent: .27=27%. The percent of increase is 27% :) hope this helps
