What will the value be for Y when X equals 0 in the equation Y = -2(X + 3) + 5?

What will the value be for Y when X equals 0 in the equation Y = -2(X + 3) + 5?

• A. 1
• B. -1
• C. 0
• D. 2

Answer: (B)

To determine the value of Y when X equals 0 in the equation Y = -2(X + 3) + 5, we start by substituting 0 for X. The equation becomes: Y = -2(0 + 3) + 5. Calculate the value inside the parentheses first: 0 + 3 equals 3. Now substitute that back into the equation: Y = -2(3) + 5. Multiply -2 by 3: Y = -6 + 5. Now, perform the addition: -6 + 5 equals -1. Thus, when X equals 0, Y equals -1. This shows that the calculation of Y at the specified value of X leads straightforwardly to the answer, confirming the relationship outlined in the equation.

To determine the value of Y when X equals 0 in the equation Y = -2(X + 3) + 5, we start by substituting 0 for X. The equation becomes:

Y = -2(0 + 3) + 5.

Calculate the value inside the parentheses first:

0 + 3 equals 3.

Now substitute that back into the equation:

Y = -2(3) + 5.

Multiply -2 by 3:

Y = -6 + 5.

Now, perform the addition:

-6 + 5 equals -1.

Thus, when X equals 0, Y equals -1. This shows that the calculation of Y at the specified value of X leads straightforwardly to the answer, confirming the relationship outlined in the equation.
