[Done] Solve the equation: \[ \log(6x - 3) = -4 \]

[Done] Use the function rule, \( y = 2x + 5 \), to find the values of \( y \) when \( x = 1, 2, 3, 4 \). Write the answers as ordered pairs that would be used to graph the function. Show your work. 1. For \( x = 1 \): \[ y = 2(1) + 5 = 2 + 5 = 7 \] Ordered pair: \((1, 7)\) 2. For \( x = 2 \): \[ y = 2(2) + 5 = 4 + 5 = 9 \] Ordered pair: \((2, 9)\) 3. For \( x = 3 \): \[ y = 2(3) + 5 = 6 + 5 = 11 \] Ordered pair: \((3, 11)\) 4. For \( x = 4 \): \[ y = 2(4) + 5 = 8 + 5 = 13 \] Ordered pair: \((4, 13)\)
