ELEN [110]3 years ago
7 0

Answer:

I think it is 90 degrees

Step-by-step explanation:

Line PQ and PS are perpendicular, meaning it would be 90 degrees.

Long way:

Plus, if you add both 7x-9 and 4x+22 with like terms, you get 11x+13, since it is perpendicular, 11x+13=90

Subtract 13 on both sides, you get 11x=77

x is 7 and inserting 7 would lead to 90.

A function is defined as {(0,1), (2,3), (5,8), (7,2)}. Issac is asked to created one more ordered pair for the function. Which o
SSSSS [86.1K]

A function is  a relation that maps to each input value exactly one output value.

Given the function as {(0,1), (2,3), (5,8), (7,2)}, you can rewrite it

  • f(0)=1;
  • f(2)=3;
  • f(5)=8;
  • f(7)=2.

Now consider all options:

  1. the ordered pair (0,2) cannot be add to this function, because then f(0)=2, but you have already that f(0)=1 and output value should be one value;
  2. the ordered pair (5,3) cannot be add  to this function, because then f(5)=3, but f(5)=8 (given) and output value should be one;
  3. the ordered pair (7,0) cannot be add to this function, because then f(7)=0, but f(7)=2;
  4. the ordered pair (1,3) can be add to the set, because f(1)=3 is unique ordered pair (with 1st coordinate 1)

Answer: correct option D
