Answer:
every difference x-y is the same for related pairs of x and y
Answer:
OPTION A
OPTION C
Step-by-step explanation:
A relation becomes a function when it satisfies the following two conditions:
(i) Any element from the domain can only be mapped to only element in the co-domain.
(ii) No element in the domain should be left unmapped.
Note that an element in the co-domain need not have a pre - image.
OPTION A: Every element has an image and no element is mapped to two different elements on the co - domain. so, it is a function.
OPTION B: The element 9 is mapped to both 4 and 6. Condition (1) is not satisfied. So, it is not a function.
OPTION C: Both the conditions of a function are satisfied. So, OPTION C is a function. Note that the element 8 in the co - domain does not have a pre - image but it is still a function.
OPTION D: Element 1 in the domain is mapped to two elements. Violation of Condition (i). So, it is not a function.
Answer:
13-+4
Step-by-step explanation:
Answer: Angle 4 is 167 degrees. Angle 5 is 13 degrees.
Step-by-step explanation:
If angle 1 is 167 degrees, then angle 4 is also 167 degrees because angle 4 is vertical to angle 1. Vertical angles are each of the pairs of opposite angles made by two intersecting lines. Knowing this, you know angle 2 is also 167 degrees because it is vertical to angle 1. To solve, a straight line is 180 degrees. 180-167 is 13 degrees therefore angle 5 is 13 degrees
