Given that a*b=2a-3b, then 2*(-3)=

Given that a*b = 2a-3b,then 2*(-3)= 13

The given binary operation is:

a*b = 2a  -  3b

Applying this binary operation to 2*(-3), we are going to substitute a = 2 and b = -3 into the binary operation a*b = 2a  -  3b

If a = 2 and b = -3:

2*(-3)  =  2(2)  -  3(-3)

2*(-3)  =  4   +  9

2*(-3)  =  13

Therefore, given that a*b = 2a-3b,then 2*(-3)= 13

Step-by-step explanation:

Given: a*b=2a-3b

To find: 2*(-3)

Solution:

Numbers that are used for counting are known as natural numbers. Number along with the digit 0 are known as whole numbers.

In the question, is used to define relation between a and b as

To find 2*(-3), use the given condition: a*b=2a-3b

reduce the friction between its moving parts

step-by-step explanation:

in fact, by reducing the friction between the moving parts of the machine, it is possible to reduce the energy wasted due to this friction; therefore, more input energy is converted into useful work, and this will improve the efficiency of the machine.
