Mathematics

Answer:

Subtract: 5 - 9i = 5-9i  

Add: the result of step No. 1 + (-4) = (5-9i) + (-4) = (5-4) + (-9i) = 1-9i  

Add: the result of step No. 2 + 7i = (1-9i) + 7i = 1 + (-9+7)i = 1-2i

Subtract: 1 - 2i = 1-2i  

Subtract: the result of step No. 1 - 4 = (1-2i) - 4 = (1-4) + (-2i) = -3-2i  

Add: the result of step No. 2 + 7i = (-3-2i) + 7i = -3 + (-2+7)i = -3+5i

Step-by-step explanation:

Answer: 2.)non function 3.)non function 4.) function 5.)non function 6.) non function 7.)function 8.)non function PART B 1.)non function 2.)function 3.) function

Step-by-step explanation: a function is when the domain (x) all each have one answer like (-2.6)(7,4)(8,6) there can be repeating ranges (y) just not domains.

A non function is when one domain (x) has multiple ranges(y) like (7,2)(-9,6)(7,9) the 7 repeats twice giving it two ranges, which causes it to be non functional. hope that helped :))

Which statement listed below illustrates the reflexive property of congruence
Vlad1618 [11]

Option D:

\triangle K L M \cong \triangle K L M

Solution:

Reflexive property of congruence:

<em>Reflexive property of congruence means the geometric figure is congruent to itself.</em>

Option A: If \triangle K L M \cong \triangle P Q R \text { and } \triangle P Q R \cong \triangle S T U \text { , then } \triangle K LM\cong \triangle S T U

From the definition of reflexive property, it is not true.

This is transitive property of congruence triangles.

Therefore it is false.

Option B: \text { If } \triangle  KL M \cong \triangle P Q R \text { , then } \triangle P Q R \cong \triangle S T U \text

From the definition of reflexive property, it is not true.

Therefore it is false.

Option C: \text { If } \triangle K L M \cong \triangle P Q R \text { , then } \triangle P Q R \cong \triangle K L M

From the definition of reflexive property, it is not true.

Therefore it is false.

Option D: \triangle K L M \cong \triangle K L M

Here, ΔKLM is congruent to itself.

This statement illustrates the reflexive property of congruence for triangles.

Therefore, it is true.

Hence option D is the correct answer.

25g = 17.5 pleaseeee I needed am answerrrrr ASAP​
goldenfox [79]

Answer:

g = 0.7

Step-by-step explanation:

To isolate g, we do the same thing to both sides.

Dividing both sides by 25 gives us:

g = 17.5/25

g = 0.7
