Pls help (will mark brainiest) The equation of a line of best fit for a data set is y=4.5x−12.3. Which is the residual, r, of the point (5, 8) found in the data set?

Answer asap ! the shortest path from point a to point b goes through a pond. to avoid the pond, you must walk straight 34 meters along one edge of the pond, then take a 90 degree turn, and again walk straight 41 meters along another edge of the pond to reach point b. about how many meters would be saved if it were possible to walk through the pond? a. 11 m b. 20 m c. 30.45 m d. 21.73 m

Write numerical coefficient of y² in the expression 2x² - 15xy – 7y²

Twice the sum of a number and 4 is equal to three times the difference of the number and 7. find the number.
