Answer:
Substitution property of equality
Step-by-step explanation:
Given
and 
Then
Required
State the property
From the list of options, (d) answers the question.
This is so because:
Substitution property of equality states that
If 
then 
In other words, both can replace one another.
So if , then 2y + 1 can be substituted for x in
So:
becomes
<em>Hence, it is substitution property of equality</em>
Answer:no its 69. :)
Step-by-step explanation:
A) √50 = 2√25 . Her mistake was that she confused the radicand (25) & the outside factor to the radicand that is 2. The write answer is 5√2 & not the opposite
b) Find 2 numbers where their square nears the lower & the upper end of 50.
For instance 7² = 49 & 8² =64 are the nearest lower & upper numbers that encompass 50
Hence we can write the following inequality:
49<50<64 & √49<√50√64 ==> 7<√50<8
So the √50 is nearer to 7² rather than 8².
Then let's try 7.1² =50.41 Which is an acceptable approximation
