Answer:

B. x ≤ 2.

Step-by-step explanation:

56 - 10x ≥ 20 + 8x

-18x ≥ -36

x ≤ -36/-18 = 2. ( Note that the inequality sign flips because we are dividing by a negative value).

4)
x + 5 < 14

Subtract 5 on both sides
x + 5 - 5 < 14 - 5
x < 14 - 5
x < 9
Answer is D.

5)
< (less than) and > (greater than) have empty circles because the number is not included.
For example, x > 5
5 is not a solution because we are looking for all x that is greater than 5.

≤ (less than or equal to) and ≥ (greater than or equal to) have a closed circle because the number is included.
For example, x ≤ 7
7 is a solution because we are looking for all x that is less than or equal to 7.

Answer is C.

6)
4(x-1) ≥ 8
Divide 4 on both sides
(x-1) ≥ 2
Add 1 on both sides
x ≥ 3

Answer is D.

let´s see , we have P1(3,9) and P2(4.14)

first let's find its slope

$m=\frac{y2-y1}{x2-x1} = \frac{14-9}{4-3}$
