Answer:
6+6=12
Step-by-step explanation:
Hey there!
2x^2 - 5 / x + 9
= 2(-1)^2 - 5/ -1 + 9
= (2(-1)^2 - 5) / (-1 + 9)
= (2(1) - 5) / 8
= (2 - 5) / 8
= -3 / 8
≈ -0.375
Therefore, your answer is:
-3/8 OR -0.375
EITHER OF THOSE SHOULD WORK BECAUSE THEY ARE EQUIVALENT TO EACH OTHER!
Good luck on your assignment & enjoy your day!

Answer:
20
Step-by-step explanation:
8x=6x+5 (subtract 6x from both sides)
2x =5 (divide by 2 both sides)
x=2.5
8x= 8*2.5 = 20 (substitute 2.5 for x)
or 6x+5 = 6(2.5)+5 = 20 (substitute 2.5 for x)
