Answer: D
Step-by-step explanation:
The degree of the equation is 1.
The reason it's not A is because |x| can be represented as a piecewise function composed of 2 different linear functions.
Answer:
The statement 
is equivalent to 
, 
Step-by-step explanation:
We need to prove that the following statement is equivalent to with the use of Theorem 2.1.1.
So
by De Morgan's law.
by the Double negative law
by the Distributive law
by the Negation law
by Universal bound law
Therefore
3x + 2y = 39
-3x -3x
2y = 39-3x
— ———
2 2
y= 19.5 - 3x/2
plug (19.5 - 3x/2) for y
1.5x - 2(19.5 - 3x/2)= 39
x= 17.33333333334
There are 16 ounces in a pound. So just multiply
16 x 18 = 288
18 pounds = 288 ounces
Hope this helps.
