The Greene family and the Carson family plan to take a vacation together next summer. The Greene family has $75 saved so far for the trip and plans to save an additional $10
per week. The Carson family has $25 saved and plans to save $15 more each week. Mr.
Greene estimated that the two families would have the same amount saved after 10
weeks. Is Mr. Greene’s estimate reasonable? Solve BY SETTING THE TWO EQUATIONS
EQUAL TO EACH OTHER.

Variables: Method:
Equation 1: Equation 2:

Solution: Answer to the question asked:

Factor the following expression. 27y3 – 343 a. (3y + 7)(9y2 + 2ly + 49) b. (3y – 7)(9y2 + 2ly + 49) c. (3y – 7)(932 – 217 + 49) d. (3y + 7)(92 – 2ly + 49)

Does anyone know how to solve and graph this: 4 + | a + 2 | < 7the only part i don't get is the "4 +"

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). =
