A is 23 and the answer to b is 77
Just rank every pair of numbers for example:
The first one is: 1,-3.
2•1-3•-3>12
2+9>12
11>12
That's Incorrect. The first pair of numbers doesn't match the inequality.
Now do the same thing to all the other pairs of numbers.
X is your number
double it means 2 times x or 2x
add 4
2x+4
subtract my number
2x+4-x=x+4
subtract 3
x+4-3=x+1
the result is x+1 or your number plus 1
Hello the answer would be approximately 394.57 good luck with the test
2x +9 <0
x > -12
2x<-9
2x<-9/2 (9/2 = 4.5)
x >-12
the answer is all integers between -12 and -4.5
-11, -10, -9, -8, -7, -6, -5
