Question

10. Evaluate x(-y + z) for x = − 1, y = 2, and z = 5. -3 3 7 -7

Answer 1

Answer:

-3

Step-by-step explanation:

x(-y+z) replace with the values given above

-1(-2+5)

Answer 2

Answer:

Option A

Step-by-step explanation:

We are given the values of x, y, and z, which is -1, 2, 5 respectively.

Let us substitute the values into the expression provided to determine a specific numerical value of the expression, when x = -1, y = 2, and z = 5.

⇒ x(-y + z) = x(z - y) = -1(5 - 2)

Finally, let's simplify the expression as necessary.

⇒ -1(5 - 2)

⇒ -1(3)

Integer rule: Any number multiplied by -1 is the number's opposite.

⇒ -3

Therefore, the correct option is "Option A"
