Step-by-step explanation:
you can plug the x value (9y) into the second equation
5(9y) + 3y = -48
45y + 3y = -48
48y = -48
y = -1
x = 9(-1)
x = -9
Answer: I think it's four
Step-by-step explanation:
Answer: Third option is correct
Step-by-step explanation: The y-intercepts match the constants (b in y=mx+b format) The y-values shaded above the line y≥2x+4 are correct. The y-values shaded in the region below the y≤2x -2 are also correct.
Residual is the difference between the y value of scatter plot and y value of regression equation
A scatter plot containing the point (6, 8), the y value of scatter plot is 8
y=6x+4, to get y value of regression equation we plug in 6 for x
y = 6(6) + 4 = 40
Residual e = y value of scatter plot - y value of regression equation
=8 - 40 = -32
Answer : e=-32
