The variable being tested in an experiment is the (b) response variable
<h3>How to determine the variable name?</h3>
The statement is given as:
<em>what is the variable being tested in an experiment?</em>
As a general rule, the variable being tested in an experiment is referred to as the dependent variable
The dependent variable is represented with y and it is also known as the response variable
Hence, the variable being tested in an experiment is the (b) response variable

3.9+3.9 = 7.8
7.8 * 3.9 * 3 = 91.26
5.7 * 3.9 * 3 = 66.69
66.69 + 91.26 = 157.95
Answer is A
Answer:
b
Step-by-step explanation:
X+y=1
Subtract y from both sides
x=-y+1
Substitute into the other equation
-2(-y+1)+4y=6
Divide by -2
-y+1+2y=3
Subtract 1
-y+2y=2
Add like terms
Y=2
Substitute into first equation
X+2=1
Subtract 2 from both sides
X=-1
(-1,2)
I hope this helps :)
-2(-y+1)+4y=6
2y-2+4y=6
2y+4y=12
6y=12
Y=2
