Answer: - 2x^2 + 4x + 3
Step-by-step explanation:
( -x^2 - 4x - 5) + ( -x^2 + 8x + 8)
Take out parentheses:
- x^2 - 4x - 5 - x^2 + 8x + 8
Write in a way so that like terms are grouped together:
- x^2 - x^2 - 4x + 8x - 5 + 8
Combine 'x^2' terms:
- 2x^2 - 4x + 8x - 5 + 8
Combine 'x' terms:
- 2x^2 + 4x - 5 + 8
Combine integers:
- 2x^2 + 4x + 3

as 6^3=6*6*6=216
∛(-216)=-6
∛(mn)=(∛m)(∛n)
and
if you have the 3rd root of a negative number, the root will be negative
∛-216=(∛216)(∛-1)
we know that 216=6^3 (you know, just fun fact)
6(∛-1)

Answer:
f(4) = (4)² + 5(4) = 36.
g(9) = [3(9) - 4]/2 = 23/2.
f(-3) = (-3)² + 5(-3) = -6.
g(-6) = [3(-6) - 4]/2 = -11.
Set f(x) = 14.
=> x² + 5x = 14
=> x² + 5x - 14 = 0
=> (x + 7)(x - 2) = 0
=> x = -7 or x = 2.
Set g(x) = -28.
=> (3x - 4)/2 = -28
=> 3x - 4 = -56
=> 3x = -52
=> x = -52/3.
Answer:

-11
-2, 7
-17.333 / - 17⅓
Step-by-step explanation:
f(4) = 4² + 5(4) = 16+20 = 36
g(9) = 3(9)-4 ÷ 2 = 23÷2 = 11.5
f(-3) = (-3)²+5(-3) = 9 - 15 = 6
g(-6) = 3(-6)-4 ÷ 2 = - 22 ÷ 2 = - 11
f(x) = 14
x² - 5x = 14
x² - 5x - 14 = 0
(x+2) (x-7) = 0
x = - 2 or x = 7
g(x) = -28
3x - 4 = - 56
3x = - 52
x = - 52/3 = - 17 ⅓

y-y1=m(x-x1).
Here y1 = 2 according to the given equation.
and x1 = (-6).
Therefore,the line passes through the point P(x1,y1) or
P(-6,2).
Final Answer:P(-6,2).
