Answer:
1. C
2. A
3. B
Step-by-step explanation:
1. 5x + 20 + 16 = 5x+36
2. 3x - 15 - x = 2x-15
3. 8x + 12 - 7x = x+12
X= <span>√(54-3x)
square both sides:
x^2=54-3x
bring everything to the left:
x^2 + 3x - 54= 0
solve using quadratic formula:
x= (-3 +/- </span>√(9- 4(-54)))/2=
(-3+/- <span>√(9+216))/2=
(-3 +/- </span><span>√225/2=
(-3 +/- 15)/2=
two options:
1) x= (-3+15)/2= 12/2=6
2) x= (-3-13)/2= -18/2= -9</span>
Answer:
f(x) = x^2 g(x) = -2/5 x^2
Suppose x = 5 then f(5) = 25 and g(5) = -2/5 (25) = -10
g(x) is less than f(x) and g(x) is below the x-axis if x is positive
Only (D) matches these requirements
