So if in the upper (400), 100 of them said no then 300 upper said yes. Add 100 and the 450 that said from the lower to get 550 as your answer.

Answer:

$x(3x^3+ 5x + 2)$

Step-by-step explanation:

The given equation is :

$3x^4 + 5x^2 + 2x$

Taking x common from the above equation.

$x(3x^3+ 5x + 2)$

Nothing can be taken from above equation now. We can write the answer as :

$x(3x^3+ 5x + 2)$

Hence, this is the required solution.

Answer:

1. -4x < 8

2. 4x < 8

3. When something is done to one side of the equation, the same thing must be done to the other side. Dividing each side by -4 in part A would cause the sign to flip because the sign is always flipped when dividing by a negative. Because 4 in 4x (part B) is not negative, the sign is not flipped.

1. 3rd one

2. f(x) = 7x - 5
f(2) = 7(2) - 5
f(2) = 14 - 5
f(2) = 9

3. c(n) = 0.75n - 0.25

4. (0,0)(2,4)
slope = (4 - 0) / (2 - 0) = 4/2 = 2
answer is : y = 2x
