Question

Write the expanded form of the expression: -y(0.5 - 8).

A) -0.5y + 8y
B) -4.5y
C) 0.5y - 8y
D) -7.5y

Answer 1

The expanded form of the expression -y(0.5 - 8) is -0.5y + 8y, which simplifies to 7.5y.

Step-by-step explanation:

The question is asking to write the expanded form of the expression -y(0.5 - 8). To expand this expression, you distribute the -y across the terms inside the parenthesis:

• -y * 0.5 = -0.5y
• -y * -8 = +8y

Putting it all together, the expanded form of the expression is -0.5y + 8y, which simplifies to 7.5y since -0.5y + 8y = 7.5y.
