When a student solved the equation log x + 4 = 8, they arrived at the answer x = 99,999,996. describe a possible reason for the error and give the correct solution.

Step-by-step explanation:

The student has  considered together, that looks a possible reason for the error because considering will give

Thus we say the and are separate.

Solving ,

We need to isolate

Subtracting from both side

Taking anti-log both side gives,

Thus is the appropriate answer.

answer: sorry i can't you.

step-by-step explanation:

c. y = 1/4 x + 5

step-by-step explanation:

first, put the equation of the line on the graph into slope-intercept form

(y = mx + b):   y = -4x + 8

second, a perpendicular line has to have "an opposite/reciprocal slope" to the original slope. so, find the "m" value in your original equation (it's -4, right? )

original slope: m = -4   perpendicular slope: change the sign to its opposite and find the reciprocal ("flip" the number)

new slope is now positive (b/c the original slope was negative 4), and it's 1/4 (not the original slope of 4 or 4/1)
