(3) Explain how you can tell that the point (5, 13) is a solution to the system shown without formally solving the system.
y = 4x - 7
2x + y = 23

The diagram represents the polynomial 4x2 + 23x – 72. what is the factored form of 4x2 + 23x – 72? (4x + 8)(x – 9) (4x – 8)(x + 9) (4x + 9)(x – 8) (4x – 9)(x + 8)

Car a and car b were in a race .the driver of car b claimed that his car was twice as fast as car a

4. bob solved the inequality problem below incorrectly. explain his error and redo the problem showing the correct answer. −2x + 5 < 17 −2x + 5-5 < 17-5 -2x/-2 < 12/-2 x < -6
