Answer:
A = 48
Step-by-step explanation:
In this equation, we can factor out the expression
. If we do so, the expression becomes:

We can simplify to get:

and get:

Therefore, A = 48
Answer:
25 2/7
Step-by-step explanation:
88.50/3.50 divide 88.50 by 3:50
First we need to find the slope of line k. Using the slope formula, we fill in accordingly:

. The slope is -3/2. The slope of a line that is perpendicular to line k will have the opposite sign (so, positive) and will be the reciprocal of the line k's slope (so, 2/3). You could also say, more "mathematically legal", that the product of the slopes of perpendicular lines is -1, but it's easier to just say that they are opposite reciprocals. The slope you're looking for is 2/3. Choice 3 above.
Y = (x - 2)/3
3y = x - 2
x = 3y + 2
Therefore, the inverse of y = (x - 2)/3 is y = 3x + 2
