Answer:
x = 19°
Step-by-step explanation:
m∠DBA = m∠CBE = 71 because they are vertical angles
∠A and ∠DBA are complementary angles because the acute angles of a right triangle are complementary
So, m∠A + m∠DBA = 90
x + 71 = 90
x = 19°
Answer:
The restrictions will be:
x ≠ 0;
x² ≠ 0 ⇒ x ≠ 0 ;
5x² ≠ 0 ⇒ x² ≠ 0 ⇒ x ≠ 0;
Step-by-step explanation:
As we know that
There are two genuine reasons why domains are restricted.
We cannot divide the expression by 0 as it would be undefined then.
We cannot take the square root of a negative number, as the result will not be a defined.
Considering the expression
As we can not put x = 0 in the denominator as it would make the expression undefined.
In other words, the certain values which make the denominator equal to zero for a rational expression will be restricted values.
Hence, the restrictions will be:
x ≠ 0;
x² ≠ 0 ⇒ x ≠ 0 ;
5x² ≠ 0 ⇒ x² ≠ 0 ⇒ x ≠ 0;
Answer:
C
Step-by-step explanation:
C) 2
Put all the numbers into one row and cross them all out until there's only one left. Hope this helps! :)
STEPS:
-1-6X-6>-11-7X
GROUP LIKE TERMS
-6X-1-6>-11-7X
SUBTRACT THE NUMBERS:-1-6=-7
-6X-7>-11-7X
ADD SEVEN TO BOTH SIDES
-6X-7+7>-11+7-7X
SIMPLIFY
-6X>-7X-4
ADD 7X TO BOTH SIDES
-6X+7X>-7X+7X-4
SIMPLIFY
X>-4
SO THE ANSWER IS X>-4
