Which expression identifies the multiplicative identity property

Step-by-step explanation:

5x(1)=5x

The answer is A

Step-by-step explanation:

The multiplicative identity property is applied to numbers in the operation of multiplication. The property states that when a number is multiplied by the number 1 (one), the product will be the number itself. This property is applied when numbers are multiplied by 1. Here, 1 is known as the multiplicative identity element because when we multiply any number with 1, the obtained result will be the same number. This property can be applied to real numbers, complex numbers, integers, rational numbers, and so on. The multiplicative identity property is expressed as: a × 1 = a, where 'a' is any real number.

Example:

44 × 1 = 44, where 44 is the number on which we applied the multiplicative identity.

Note: The multiplicative identity is not applied when any number is multiplied by -1 because the result will not be the same number.

For example, 23 × -1 = -23

i dont know sorry

step-by-step explanation:

y = 5x + 17

step-by-step explanation:

a perpendicular line will be the opposite reciprocal slope of the given equation.   the slope given is -1/5 so the opposite reciprocal is 5

find b:

7 = 5 (-2) + b

7 = -10 + b

17 = b

write equation

y = 5x + 17
