Graph the system of equations:             x+y=202x-y=10

Solve the system of equations. 2x-y+5z=-7x+y-2z=-2x-y+4z=-4

Match each operation with it’s correct answer.

How many solutions does each system of equations have? You can graph to find the answers or solve algebraically. (Each ordered pair (x,y) is one solution.)

Perform the row operation(s) on the given augmented matrix in the order given. a )   – 4 R 1 + R 2 → R 2 b )   – 2 R 1 + R 3 → R 3 c )           5 R 2 + R 3 → R 3   

Solve the system by any means and only enter the y value. x-7y=-11 5x+2y=-18

Solve the system of equations by substitution. 5 x – 2 y = – 1 x + 4 y = 35

Select the function that matches the description.Has 2 vertical asymptotes at x=3, x=-3Has 1 horizontal asymptote at y=5 

Suppose y=x2+12x+6 and enter the appropriate values below. Only enter the number. The y-value of the y-intercept is y=[BLANK-1]. The y-value of the vertex is y=[BLANK-2]. The x-value of the vertex is x=[BLANK-3]. The axis of symmetry is x=[BLANK-4]. When x=2, y=[BLANK-5].

A rock is thrown upward from the top of a 112-foot high cliff overlooking the ocean at a speed of 96 feet per second. The rock’s height above ocean can be modeled by the equation h(t)=−16t2+96t+112. Do not enter units in answers. a. When does the rock reach the maximum height? Enter value for t here. t=[BLANK-1] b. What is the maximum height of the rock? Enter maximum height here. h=[BLANK-2] c. When does the rock hit the ocean? Enter value for t here. t=[BLANK-3]
