(-2,-7), (-1,-4), (0,-1) (1,2)
Inputs : -2,-1,0,1
Outputs: -7,-4,-1,2
Answer:
M=-2x+y-1 / x2
Step-by-step explanation:
x > -1
-2x+5 < 7
-2x<2
Now since you divide by (-1) to get positive 2,you need to flip the sign
(-2)/(-1)= 2 2/(-1)=-2
SO
2x>-2
x > -1
To check the solution do not replace the x by -1 because it shouls be more than -1 (You can choose 0,1,2,3....)
Example choose x=3
-2x3+5<7
-6+5<7
-1<7
Answer:
x=62
Step-by-step explanation:
152-90(because of the right angle)
the 28 is a red herring
Answer:
B
Step-by-step explanation:
use quadratic formula: (-b ±√b²-4ac) ÷ 2a
a = 10, b = -9, c = -6
