X: 1, 2, 3, 4, 5
y: 0, 1, 0, 2, 0
function: (1,0) (2,1) (3,0) (4,2) (5,0)
function is identified as a special kind of relation wherein the x-coordinate will only have one corresponding y-coordinate.
inverse of the relation is the interchange of the x and y coordinates.
inverse: (0,1) (1,2) (0,3) (2,4) (0,5)
The inverse is not a function. There are more than one x-coordinate that results to different y-coordinates. This is made evident when x = 0 ; y = 1,3, and 5.

Answer:
smaller number = 623
middle number = 625
larger number = 627
Step-by-step explanation:
Variable: X = smallest number
If these numbers are consecutive and odd, then the numbers would be:
x, x+2, x+4
x + (x + 2) + (x + 4)= 1875
3x + 6 = 1875
3x = 1869
x = 623
x + 2 = 625
x + 4 = 627
Check:
623 + 625 + 627 = 1875
Answer: 6
Step-by-step explanation:
2*3*6=12
12/2=6
formula= b*h/2
The answer is: Each bag of flour weighs 1,32 kg.
If we the total weight of the bags is given, and we know both the number of bags of flour and sugar, and we also know the weight of each bag of sugar, then we have to find the unknown, which is X. 30 times X plus 4 times the weight of a bag of sugar would equal 42.6kg. Next step is to put the unknown on one side and the known values on the other side. We have 30 times X equals 42.6 minus 4 times 0.75.
To find X we need to divide the value with 30, or to sum up
30X + 4*0.75 = 42.6
30X + 3 = 42.6
X = (42.6 - 3) / 30
X = 1.32 kg
