Answer:
Part A : 4 (m+3+5m) = 4(6m+3) = 24m+12
Part B: 4 (m+3+5m) combine like terms
4 (6m+3)
24m + 12 Distribution
Part C: m = 3 random number
4 (3 + 3 + 5(3)) = 24(3)+12
4(21) = 72 + 12
84 = 84

The correct option is (4).
Step-by-step explanation:
The complete question is:
Let f(p) be the average number of days a house stays on the market before being sold for price p in $1,000s. Which statement best describes the meaning of f(275)?
- Houses sell on the market for an average of $275,000 and stay on the market an average of 275 days before being sold.
- Houses sell for an average of $275,000.
- f(275) indicates houses stay on the market an average of 275 days before being sold.
- f(275) represents the average number of days houses stay on the market before being sold for $275,000.
Solution:
The function f (p) is defined as the average number of days a house stays on the market before being sold for price <em>p</em> in $1,000s.
The function provided is: f (275)
That is, <em>p</em> = $275,000.
So, the function (275) describes the average number of days a house stays on the market before being sold for price $275,000.
Thus, the correct option is (4).
Step-by-step explanation:
y = (-4/9)x + 3
-4/9 is the slope of the line. the factor is x is the slope in every line equation. the slope is always the ratio y/x.
the parallel line must have the same slope, of course.
but the y-intercept will be different.
so, its line equation looks like
y = (-4/9)x + c
we use the provided point coordinates to calculate this c.
4 = (-4/9)×9 + c
4 = -4 + c
c = 8
therefore, the parallel line equation is
y = (-4/9) + 8
a perpendicular line is a line that intercepts the original line by an angle of 90 degrees.
that means that its slope switches the original x and y, and also flips the sign.
the perpendicular slope is therefore : 9/4
so, the line equation looks like
y = (9/4)x + c
again, we use the provided point coordinates to calculate c :
4 = (9/4)×9 + c
4 = 81/4 + c
16/4 = 81/4 + c
-65/4 = c
the perpendicular line equation is
y = (9/4)x - 65/4
