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:
- 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;
- 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;
- the ordered pair (7,0) cannot be add to this function, because then f(7)=0, but f(7)=2;
- 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
3/4 box = 12 oz
we first need to find 1/4 of a box. to do that divide both sides by 3
1/4 box = 4 oz
for a full box which is 4/4 multiply both sides by 4
1/4 x (4) = 4 x (4) oz
4/4 ( or one whole) = 16 oz

Answer:
y > 4x + 2
Step-by-step explanation:
Y is above the line so the value has to be greater than the line (or equal to, possibly). So it represents > or ≥
A dotted/dashed line is non-inclusive, so it represents < or >.
Since it is both above the line AND non-inclusive, we would use this sign:
>
and this equation :)
y > 4x + 2

6 times a number is 72.
Divide 72 by 6 to get the number.
72/6=12
Check:
6 x 12=72
Hope this helps.
