Answer:
you want to isolat U on one side, so subtract 9/-4 from both sides to end up with (9/-4) - 9 = u, then solve. (9/-4)-9 = -11.25, so -11.25 = u
Answer:
4pi
Step-by-step explanation:
Area of a circle is pi (r^2)
Radius is 2, 2 squared is 4, 4 times pi is 4pi.
the slope intercept form is y=mx+b
since the line intersects at (0,3) b= 3
since the slope is 0 m= 0
so the equation would be y=0x+3 or y=3
Answer:
<u>Part A</u>:
(
is equal to all real numbers)
<u>Part B</u>:
Step-by-step explanation:
<u>Part A</u>:
Given 
, combine like terms:
Add 7 to both sides:
Since this is merely a true statement for all real numbers (reflexive property), this equation is true for any real value of .
Therefore,
( is equal to all real numbers).
<u>Part B</u>:
Using arbitrary values 
as requested in part B, verify:
