Answer:
The total number of pants in Mary's closet = 15
Step-by-step explanation:
Here, given:
40% of slacks in her closet = 6 pairs
Let us assume the total pants in her closet = m
So, according to the given data:
40% of m = 6 pairs
⇒ m = 15
Hence the total number fo pants in her closet = 15
Answer:
y = - x + 9
Step-by-step explanation:
the equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
calculate m using the slope formula
m =
with (x₁, y₁ ) = (0, 9) and (x₂, y₂ ) = (9, 0) ← 2 points on the line
m = =
= - 1
the line crosses the y- axis at (0, 9 ) ⇒ c = 9
y = - x + 9 ← equation of line
