If you have a product of variables, it is not linear.
A. x(y - 5) = 2
xy - 5x = 2
xy is a product of variables, so option A is not linear.
Y=x+3
-3x+3(x+3)=4
-3x+3x+9=4
9=4
Since this statement is false, there are no ordered pair solutions to this problem.
Answer:
4
Step-by-step explanation:
because 4 Times 3 equals 12 so less than or equal to hope this helps
Answer: 1.02
Step-by-step explanation:
The least square regression equation for the information provided is y = 9.72x - 40.776
<u>The general equation of a regression model can be expressed thus</u>:
Calculating slope, b :
- b = 0.81(177.6 / 14.8) = 9.72
<u>Plugging the values of b, y and x into the equation in other to calculate c</u> :
696 = 9.72(75.8) + c
696 = 736.776 + c
c = 696 - 736.776
c = - 40.776
Therefore, the linear regression model can be expressed as : y = 9.72x - 40.776
