Which pair of equations could not be used to solve the following equations for x and y? 4 + 2 = 22
−2 + 2 = −8

A.4 + 2 = 22 B. 12 + 6 = 66 C. 4 + 2 = 22 D. 8 + 4 = 44
2 − 2 = 8 6 − 6 = 24 -4x + 4y =-16 -8x + 8y = -8

Can some one explain this i got sent this. is this a threat i’m scared

Graph the system of inequalities presented here on your own paper, then use your graph to answer the following questions: y < 4x − 8 y is greater than or equal to negative 5 over 2 times x plus 5 part a: describe the graph of the system, including shading and the types of lines graphed. provide a description of the solution area. (6 points) part b: is the point (5, −8) included in the solution area for the system? justify your answer mathematically. (4 points)
