I *2. If de represents the number of feet a tortoise has crawled north of the starting line of a race and di
represents the number of feet a bare has traveled north of the same starting line, what do each of the following expressions represent?
di-da
a. d1-dh.

b. D1/12.

c. Dh/d1

the answer to this question is 3/19

step-by-step explanation:

but which class are u may know that first

b

step-by-step explanation:

the equation of a line in point- slope form is

y - b = m(x - a)

where m is the slope and (a, b) a point on the line

calculate m using the slope formula

m = (y₂ - y₁ ) / (x₂ - x₁ )

with (x₁, y₁ ) = (0, 4) and (x₂, y₂ ) = (3, - 5) ← 2 points on the line

m = = = - 3

with m = - 3 and (a, b) = (3, - 5), then

y - (- 5) = - 3(x - 3), that is

y + 5 = - 3(x - 3) → b

answer: 1.5
