Answer:

17. angle DAB=118º

18. angle DAB=126º

Step-by-step explanation:

The angle A should be 180º-85º-33º(cause the total angle in a triangle is 180º)

So you will get 62º as the angle of A.

And what the question ask is angle of DAB,so again 180º-62º=118º(A straight line is 180º)

Same goes to question 18,use 180º to minus the two angle given,you get 54º ,and then 180ºminus 54º again,the answer is 126º

<h3>Answer:  Yes it is a function.</h3>

Reason:

There are no repeated x values, so each x input leads to exactly one y output. That's why we have a function.

If we had something like (1,18) and (1,12), then the input x = 1 leading to simultaneous outputs y = 18 and y = 12 would mean we wouldn't have a function.

How do the identity and associative property work?
Ivan

Answer:

Step-by-step explanation:

The associative property is helpful while adding or multiplying multiple numbers. By grouping, we can create smaller components to solve. It makes the calculations of addition or multiplication of multiple numbers easier and faster. Here, adding 17 and 3 gives 20.

the identity property of 1 says that any number multiplied by 1 keeps its identity. In other words, any number multiplied by 1 stays the same. The reason the number stays the same is because multiplying by 1 means we have 1 copy of the number.

ANSWER ASAP PLEASE
AleksAgata [21]

Answer:

Javier,16,12

Step-by-step explanation:

From the first bag, we can pull a 1,2 or 3.  That would go on the first line of the tree diagram

From the 2nd bag, we can draw a 4,5, or 6.  That goes on the the second line under each number

From the 3rd bag, we can draw a 7,8, or 9.  That goes on the the third line under each number

Javier drew the correct tree diagram.

1,3,5,7,9 are odd numbers.  We must have at least 2 of these numbers

1,4,7            2,5,7            3,4,7

1,4,9            2,5,9            3,4,9

1,5,7                                 3,5,7

1,5,8                                  3,5,8

1,5,9                                  3,5,9

1,6,7                                  3,6,7

1,6,9                                  3,6,9

There are 16 total where there are at least two odd numbers

Multiples of 4 are 4 and 8

We must have either a 4 or an 8 but not both

1,4,7             2,4,7         3,4,7

1,4,9            2,4,9          3,4,9

1,5,8            2,5,8          3,5,8

1,6,8            2,6,8          3,6,8

There are 12 outcomes
