Answer:
162
Step-by-step explanation:
Hello:<span>
the equation is : y = ax+b
the slope is a : a×(-3/4) = -1......(
perpendicular to a line : </span>
3x+4y-22=0 : another equation is : y = (-3/4)x +22/4 with the slope : (-3/4))
<span>
a =4/3 </span>
<span>an equation is : y - 4 = (4/3)(x-2)</span>

Answer:
Difference between Observational and Experimental Data
The data collected in the study is observational data.
Step-by-step explanation:
In an experimental study, the data collected is divided into two groups. One group is the control group. The other group is the treatment group (also known as the experimental group). Data is gathered about the groups in order to compare their different outcomes and to draw conclusions if there is any causality based on the two variables. With observational data, the researcher is interested in observing the variables to determine if there is any correlation.
Y=x+138. Since $138 is added, that will be the equation (expression) x= the amount she had before and y=her current amount after the deposit.
