When u=-2, put that in where you see "u". use parentheses.
-4(-2)+4x=12
-4*-2=8 ➡positive 8 since a negative times a negative is always positive

now look for x
8+4x=12
subtract 8 from both sides. get x by itself.
-8+8+4x=12-8
4x=4➡ divide both sides by 4. a number divided by itself is 1 (unless one side is negative, then the answer is negative)
4/4=1

x=1
Answer:
Graph in attachment and Solution set is x € (⅕ ,-∞)
Step-by-step explanation:
We need to graph the solution of a inequality . For graph refer to the attachment . Let's solve out and find the solution set of inequality .
=> 5/3x < 10
=> 5 < 10 * 3x
=> 5 < 30 x
=> 5 /30 < x
=> x > 1/5
Basically we need to plot here x > 1/5 . The solution set will be , x € ( 1/5 , -∞ )
The answer is C
c+5/9 (f-32)
f=40
c+5/9(40-32)
c+40/9
=4 4/9
