I REALLY NEED AN ANSWER! WILL MARK BRAINLIEST Misha solves the following system of equations using the substitution method.

y=5−2x
3x−y=15

What is the single-variable equation she solves after substituting?

A. 3(5+x)=5−2x

B. 15+3x=5−2x

C. 3x−(5−2x)=15

D. 3x−5−2x=15

Given are five observations for two variables, x and y. xi 1 2 3 4 5 yi 3 7 5 11 14 which of the following is a scatter diagrams accurately represents the data? what does the scatter diagram developed in part (a) indicate about the relationship between the two variables? try to approximate the relationship betwen x and y by drawing a straight line through the data. which of the following is a scatter diagrams accurately represents the data? develop the estimated regression equation by computing the values of b 0 and b 1 using equations (14.6) and (14.7) (to 1 decimal). = + x use the estimated regression equation to predict the value of y when x = 4 (to 1 decimal). =
