Answer:
A) x = (-8log(6)-2log(17))/(-2log(17)+log(6))
Step-by-step explanation:
Taking the logarithm of the equation, you have ...
(x+8)log(6) = (2x-2)log(17)
Subtracting the right side from the equation gives ...
x(log(6) -2log(17)) +8log(6)+2log(17) = 0
Subtracting the constant and dividing by the coefficient of x gives ...
x = -(8log(6) +2log(17))/(log(6) -2log(17)) . . . . . matches selection A
___
You don't need to work out the whole solution to determine the correct answer choice. Once you take the initial log, you find that the x-coefficient includes a multiplier of 2log(17). This term only appears in the denominator of choice A. (The value of x will be found after dividing by the x-coefficient, so you know this must show up in the denominator of the answer.)
Answer:
The answer is A
Step-by-step explanation:
Given that the equation of line is y = mx + c and the slope is 7 :
y = 7x + c
By substituting the coordinate(8,6) into the equation, in order to find the value of c:
6 = 7(8) + c
6 = 56 + c
c = 6 - 56
= -50
y = 7x - 50

Answer:
angle E, the measure is 135
angle J, the measure is 105
Step-by-step explanation:
Supplementary angles add up to 180 degrees.
We are to identify an angle that is supplementary to angle M form the given parallel line.
From the fist diagram, angle E and angle F are supplementary to angle M because they form adjacent angles on a straight line with angle M.
If angle m is 45 degrees, then the value of its supplement is 180-45=135
From the second diagram, angle H,angle J and angle P are supplementary to angle M.
If angle M is 75 degrees, the its supplement is 180-75=105
