Answer:
(-∞ , -1) ∪ (4 , ∞)
Step-by-step explanation:
-1 > 3x + 2 or 3x + 2 > 14
-1> 3x + 2 or 3x + 2 > 14
-1 - 2 > 3x or 3x > 14 - 2
-3 > 3x or 3x > 12
-1 > x or x > 4
(-∞ , -1) ∪ (4 , ∞)

<u>Answer:
</u>
Expression x + 2my + z represents cost of order where x, y, z are cost of small , medium and large drinks (in dollars) respectively.
<u>Solution:
</u>
Given that
Juan’s family ordered a small drink and m medium drinks.
Alex family ordered m medium drinks and a large drink.
Need to write an algebraic expression which shows total cost of both order in dollars.
Let’s assume cost of one small drink = x
And assume cost of one medium drink = y
And assume cost of one large drink = z
So now cost of order of Juan’s family is equal to cost of 1 small drink + cost of m medium drinks = 1
x + m
y
= x + my
And cost of order of Alex family is equal to cost of m medium drinks + cost of one large drink
= m x y + 1 x z
=my + z
So total cost of both order in dollars = x + my + my + z = x + 2my + z
Hence expression x + 2my + z represents cost of order where x , y , z are cost of small , medium and large drinks (in dollars) respectively.
