Answer:
y = 7x - 14
Step-by-step explanation:
If the given line has slope -1/7, then any perpendicular line has the slope which is the negative reciprocal of -1/7. That is +7.
Apply the slope-intercept formula for the equation of a straight line, using 0 for y, 2 for x and searching for the y-intercept value b:
0 = 7(2) + b. Then b = -14, and the desired equation is y = 7x - 14.
Answer:
is this a maths question?
Step-by-step explanation:
By the way I don't know
Log(7x+1) - log(x-2) =1
log[(7x+1) / (x-2)] =1 or log[(7x+1) / (x-2)] =log10 (log10=1)
it means (7x+1) / (x-2) =10
Solving ===> x=7
