The another way to represent the same line, for solving 
will be: 
<u><em>Explanation</em></u>
Given equation of the line is: 
"Solving " means <u>we need to get</u> <u>alone in left side.</u> So, we will eliminate all other terms except from the left side.
First we will <u>subtract 2x </u>from both sides. So, we will get......
Now, we will <u>divide both sides by 3</u> for getting alone. So.....
Thus, the another way to represent the same line, for solving will be:
Δx (delta x) is about a secant line, a line between two points representing the rate of change between those two points. That's a "differential" (between the two points).
dx is about a tangent line to one point, representing an instantaneous rate of change. That makes it a "derivative."
Answer:
D.the treatment group (placebo or reading strategies)
Step-by-step explanation:
This cognitive psychologists wants to find out if better reading strategies when taught to students would have any effect on their test scores.
So the dependent variable in this experiment would be the test scores that she wants to find from the test.
While the independent variable would be the treatment group which is the placebo or treatment. The psychologist wants to measure outcomes in this dependent variable using changes in the independent variable (placebo/treatment).
B is the only answer that would make sense.
