Please help What is the value of this expression when a = 7 and b = -4? |2a| - b/ 3

15 1/3

Step-by-step explanation:

a = 7

b = -4

plugging the above value in |2a| - b/ 3

|2a| - b/ 3 = |2*7| - (-4)/ 3

|x| is modulus function so whatever be the value of be it negative or positive, modulus of this x is positive x

=> |14| + 4/ 3 = 14 + 4/3

=> (14*3 + 4)/3 = (42+4)/3 = 46/3 = 15 1/3

|2a| - b/ 3 = 15 1/3 when a = 7 and b = -4

step-by-step explanation:

y = | -2(-2) |     →     y = | 4 |     →     y = 4       ⇒   (-2, 4)

y = | -2(-1) |     →     y = | 2 |     →       y =   2       ⇒   (-1, 2)    

y = | -2(0) |     →     y = | 0 |     →       y = 0         ⇒   (0, 0)

y = | -2(1) |   c →     y = | -2 |     →     y =   2         ⇒   (1, 2)    

y = | -2(2) |     →     y = | - 4 |     →     y =   4         ⇒   (2, 4)
