Answer:
A
Step-by-step explanation:
From the diagram:
- P(-4,6)→P'(4,6);
- Q(-7,4)→Q'(7,4);
- R(-6,1)→R'(6,1);
- S(-2,1)→S'(2,1);
- T(-1,4)→T'(1,4).
The general rule of this reflection is
(x,y)→(-x,y)
and this is reflection across the y-axis. The y-axis has the equation x=0.
Answer:
5/6
Step-by-step explanation:
Only 5 is not divisible by 12
Given:
The product of a particular number is 65.
Second value is given by the sum of 8 and the original number.
To find:
The unknown number.
Solution:
Let x be the unknown number.
Then, second number = x+8
The product of a particular number is 65.



Splitting the middle term, we get



Using zero product property, we get
and 
and 
So, the unknown number is either 5 or -13.
Therefore, the correct option is B.
Answer:
6 7/8
Step-by-step explanation:
Since 1 cup of rice is added to 2 3/4 water
We are to determine the Amount of water to be to 2 1/2 cups of rice
Let the unknown number for water be x
So let's solve
1 cup of rice=11/4 water
5/2 cup of rice=x water
Cross multiply
x=5/2×11/4
x=55/8
X=6 7/8
Therefore,6 7/8 water is needed
