Determine the solution and the reasoning that justifies the solution to the systems of equations. (2,7), because this point is true for both equations
O (4.-6), because this point lies only on one of the two lines
O (4, -6), because this point makes both equations true
O (2.7), because the lines intersect the x-axis at these points

The depth of a lake at a certain point, wich is a function of the distance of that point from shore, is 30 feet.

The weights of players in a basketball league are distributed normally. the distance (d) of each player's weight (w) from the mean of 86 kilograms was computed as follows: d = |w - 86| if d is greater than 7 for approximately 5% of the players, what is the approximate standard deviation of the players' weights? a. 1.75 kilograms b. 3.5 kilograms c. 4.3 kilograms d. 7 kilograms

Given the system of equations presented here: 2x + 4y = 14 4x + y = 20 which of the following actions creates an equivalent system such that, when combined with the other equation, one of the variables is eliminated? multiply the second equation by â’4 to get â’16x â’ 4y = â’80 multiply the second equation by â’1 to get â’4x â’ y = â’20 multiply the first equation by 2 to get 4x + 8y = 28 multiply the first equation by â’1 to get â’2x â’ 4y = â’14
