Question

Determine whether (2, 6) and (−7, 9) are solutions to the system.

x−y<3
9x+y>8
A. Only (2, 6) is a solution to the system.
B. Neither (2, 6) nor (−7, 9) is a solution to the system.
C. Both (2, 6) and (−7, 9) are solutions to the system.
D. Only (−7, 9) is a solution to the system.
Please help get you the crow if the answer is right

Answer 1

Step-by-step explanation:The given equations are :

y=-x+2 ....(1)

y = -4x +7 ....(2)

From equation (1) and (2)

-x+2 = -4x +7

Taking like terms together

-x+4x=7-2

3x = 5

x = 1.667

Put the value of x in equation (1)

y=-(1.667)+2

y = 0.333

The solution of the equations are (1.667,0.333). The attached figure shows the graph for the equations.

Step-by-step explanation: The given equations are : y=-x+2 ....(1) y - 1
