Find the Zeros Using Descartes' Rule of Signs p(x) = 2x3 – x2 + 4x – 7

p(x) = x3 – x2 – x – 3

p(x) = x5 + 4x3 - x2 + 6x

The linear combination method is applied to a system of equations as shown. 4(.25x + .5y = 3.75) → x + 2y = 15 (4x – 8y = 12) → x – 2y = 3 2x = 18 what is the solution of the system of equations? (1,2) (3,9) (5,5) (9,3)

Solve for x. −3/4(x+2)=6 enter your answer in the box

Talia took the bus from her home to the bank and then walked back to her home along the same route. the bus traveled at an average speed of 40 km/h and she walked at an average speed of 5 km/h. to determine the time, x, that it took talia to walk home, she used the equation 40(0.9 – x) = 5x. the time of trip 2 is hours. the distance of trip 1 is km.
