A is true--------------------------
3 divided by 1/2 would be 6.
You could have 6 groups of four, or 2 groups of 12, or 4 groups of 6 or 12 groups of 2 or 3 groups of 8 or 8 groups of 3
Since 1 < x < 5, adding each side by a, where a is negative, gives
a > ax > 5a
and adding b to each side gives
a + b > ax + b > 5a + b
or
5a + b < ax + b < a + b
Since 7 < f(x) < 23, it follows that
5a + b = 7
a + b = 23
Solve for a by eliminating b :
(5a + b) - (a + b) = 7 - 23
4a = -16
a = -4
Solve for b :
-4 + b = 23
b = 27
The number that is being multiplied by the variable ( the letter) so like if you have 2X the 2 is the coefficient
