Answer:
y= 3x + 7 Step-by-step explanation:
y= -1/3x+3 (so, gradient of this line is -1/3).
formula: gradient of line one x gradient of line two= -1 (applies for 2 perpendicular lines only).
So, m1 x -1/3= -1
m1= ()
m1= 3 (gradient of perp line)
y=mx+c
4= 3 x -1 + c
7=c
therefore, y=3x+7 (eqn of the line perp to y=-1/3x+3)
Step-by-step explanation: The base of the power in the original equation becomes the base of the log. So we have .
Next, the exponent in the original equation goes on the other side of the equation and finally, the result in the
original equation goes inside the log.
So we have
which is 7³ = 343 written in logarithmic form.
