Calculate y given that x=2 and y=4(2−6x).
To solve for y, we will proceed with these steps:
- Step 1: Substitute the given value x=2 into the equation y=4(2−6x).
- Step 2: Simplify the expression inside the parentheses.
- Step 3: Perform the arithmetic operations to find y.
Now, let's work through the steps:
Step 1: Substitute x=2 into the equation:
y=4(2−6×2)
Step 2: Simplify the expression within the parentheses:
2−6×2=2−12=−10
Step 3: Calculate the value of y by multiplying by 4:
y=4×(−10)=−40
Therefore, the value of y is −40.
This solution corresponds to the choice:
Choice 3: −40
