Correct Answer: Option A
Explanation
when y = 5; x = ?; y = (frac{1}{2})x + 1
5 = (frac{1}{2})x + 1
5 – 1 = (frac{1}{2})x
4 = (frac{1}{2})x
x = 4 x 2
x = 8
What is the value of x when y = 5?
y = (frac{1}{2}) x + 1
when y = 5; x = ?; y = (frac{1}{2})x + 1
5 = (frac{1}{2})x + 1
5 – 1 = (frac{1}{2})x
4 = (frac{1}{2})x
x = 4 x 2
x = 8
