kykrilka [37]

Answer:

40

Step-by-step explanation:

area = |-17 - 26 - 24 - 13|/2 = |-80|/2 = 80/2 = 40

Y=-9x – 1<br> 8x – 4y = 92
egoroff_w [7]

Answer:

Step-by-step explanation:

y=9x-1

8x-4y=92

substitute y=9x-1

8x-4(9x-1)=92

8x-36x+4=92

-28x+4=92

-28x=92-4=88

x=88/-28=22/-7 = -3.14

y = 9(-3.14) -1 =  -28.26-1 = -29.26
