Which ordered pair needs needs to be removed in order for the mapping to represent a function? a- (-3,-4)
b-(-2,-1)
c-(1,-3)
d-(3,7)
Which ordered pair needs needs to be removed in order - 1

Answers

Answer 1
Answer:

Answer:

b - (-2,-1)

Step-by-step explanation:

A function is a mapping in which each element of the domain, or input, is mapped to one element of the range, or output.

In this mapping, the input value -2 is mapped to both 2 and -1; this makes the points (-2, 2) and (-2, -1).  If one of these two was removed, the mapping becomes a function.

The only one of these listed in the values given is (-2, -1).

If y=x and y=x+2 are the same, then how many solutions does it have

Answers

Answer:

  none

Step-by-step explanation:

"they are the same" translates to ...

  x = x +2

  0 = 2 . . . . . . subtract x from both sides. — a FALSE statement

There are no values of x or y that make this true.

_____

The two equations describe parallel lines, so they cannot be "the same." There are no points of intersection.

E + 1 13/16 = 2 5/16

Answers

e + 1 13/16 = 2 5/16

subtract 1 13/16 from each side

e = 2 5/16 - 1 13/16

borrow from the 2

e = 1 16/16 + 5 /16 - 1 13/16

e = 1 21/16-1 13/16

e = 1 8 /16

e = 1 1/2
