<span>x^4+2x³-8x-16
-------------------
       x + 2

</span>       x^3(x+2) - 8(x+2)
=  --------------------------
              x + 2

       (x+2) (x^3 - 8)
=  -----------------------
              x + 2

= x^3 - 8
= (x - 2)(x^2 + 2x + 4)

answer

(x - 2)(x^2 + 2x + 4)

Compare positive and negative slope for linear relationships. How are they the same? How are they different?
Gekata [30.6K]

Answer:

Please check explanations

Step-by-step explanation:

Slopes are generally the ratio of rise(vertical difference) to fall (horizontal difference) for set of points lying on a straight line

Positive slopes show a positive relationship between the two things we are considering while a negative one shows otherwise

They are the same in the sense that they actually represent a constant change between the coordinates of the points in the relationship we are considering.

They are different in the sense that while one represents a positive change, whereby both axes move in the same direction ( rise at same rate, fall at same rate) , the second represent a relationship in which they move in opposite directions. While one falls, the other rises and while the other rises, the second one falls which indicates an opposing movement type between the two

3) Let h(x)= |2x|-4. Find h(x) when x = -7.<br> a) -10<br> b) 10<br> c) -13<br> d) 13
svlad2 [7]

Answer:

h(x) = 10

Step-by-step explanation:

Given

h(x) = |2x| - 4

x = -7

Find h(x)

Substitute -7 for x

h(x) = |2*-7| - 4

h(x) = |-14| - 4

Absolute values return positive. So:

h(x) = 14 - 4

h(x) = 10
