Evaluate the expression
when x = ½ and y = -3
Equation:
−4xy

Step-by-step explanation:

if x=1/2 and you= -3

then, -4×1/2×-3 = -2×-3 = 6

3< x< 5

step-by-step explanation:

|x - 4| < 1

there are two solutions, one positive and one negative.   remember to flip the inequality when taking the negative solution

x-4 < 1       x-4 > -1

add 4 to each side

x-4+4 < 1+4       x-4+4 > -1+4

x< 5                 x> 3

3< x< 5

1; 35 is the ratio
