The two angles are vertical angles so they are congruent.

3x+18=5x

2x=18

x=9

5x=3x+y
5x-3x=18
2x=18
x=18/2
x=9

3•9+18=27+18=45
5•9=45
Angles have the same measure.

Johanna has to solve the system of equations using substitution. She isolates x in the second equation. Which should be her next
olganol [36]

Answer: A) 3(10 - 5y) + 6y =12

Step-by-step explanation:

As per the question , the given system of linear equation :

3x+6y=12---(i)\\\\ x+5y=10---(ii)

Here , To solve the system of equations using substitution , Johanna isolates x in the second equation and writes

x=10-5y

As per the substitution method , the next step is to substitute the isolated value of 'x' in first equation , thus the next step will become

3(10-5y)+6y=12

Hence, the correct option is A) 3(10 - 5y) + 6y =12

If the x and y values in each pair of a set of ordered pairs are interchanged the resulting set of ordered pairs is known as the
pochemuha

Answer:

Inverse of a relation

Reasoning:

the inverse of a function is a full function, this is just a set of pairs.  A set of pairs, or relation, where x and y values interchange are inverse of the relation.  A one to one function is when a function's inverse is also a function (doesn't have more than one y for each x) which can be tested for on the normal function's graph with a HORIZONTAL line test.  A normal parabola isn't one to one.  An onto function has to do with every value being used (I don't remember much about them, but once again this isn't a function, but rather a specific set of pairs/data)

Example of inverse of a relation:

Relation: {(0,5), (3,2)}

Inverse: {(5,0), (2,3)}

Example of inverse of a function:

f(x)=5x

f-1(x)=x/5

Example of a one to one function:

f(x)=x+1
