Answer with Step-by-step explanation:
Let A is non-singular
We have to prove that 
is unique.
Suppose B and C are inverse of A such that
and AC=I
By using property 
Hence, the inverse of A is unique.
Answer: -9°F
Step-by-step explanation:
From the question, we are told that the temperature at 6:00 am was -12 Fahrenheit and that the temperature increased by 1/2 Fahrenheit each hour for 6 hours.
The temperature, in degrees Fahrenheit, at noon would be:
= -12°F + 1/2(6)
= -12°F + 3°F
= -9°F
Answer:
6 = x
Step-by-step explanation:
first, we simplify the parenthesis by distributing the 4
3 = 4(x - 2) + 5 - 3x
3 = 4x - 8 + 5 - 3x
then, you add like terms
3 = x - 3
then add 3 to both sides to isolate x
6 = x
Horizontal
The Axes. The independent variable belongs on the x-axis (horizontal line) of the graph and the dependent variable belongs on the y-axis
First we have to distribute the parentheses on the left side, 2*x is 2x and 2*-3 is -6, so now the equation is 4x+2x-6 = 8x+12
Then, we can add together the two x's on the left side,
so now we have 6x-6 = 8x+12 Subtract 12 from both sides and
you get 6x -18 = 8x Then you can subtract 6x from both the sides and get
-18 = 2x Now we can divide both sides by 2, and the final answer is -9 = x
Since they are not the same and the two sides aren't unequal, there is one solution(:
Hope this is helping you(:
