Answer: A (-2, 3)
Step-by-step explanation:
1. To know which oredered pairs does not lie on the graph, you must substitute the x-coordinate of each one of thm into the function and if you obtain the y-coordinate shown in that ordered pair, then that point lies on the graph.
2. Therefore, you have:
A. x=-2
(It does not lie on the graph).
B. x=--1
(It lies on the graph).
C. x=3
(It lies on the graph).
D. x=4
(It lies on the graph).
Therefore, the answer is the option A.
Answer:
The correct answer is "50%".
Step-by-step explanation:
The given values are:
Gravel,
= 
Water,
= 
Cement,
= 1
Sand,
= 2
Now,
The total mixture will be:
= 
By substituting the values, we get
= 
= 
= 
hence,
The percentage of sand will be:
= 
= 
= 
%

Answer:
y = 4.2
Step-by-step explanation:
Pythagorean thearom: a^2+b^2=c^2
3^2+3^2=c^2
9+9=c^
sqrt18=sqrt/c^2
4.2 = c
