Does anyone know how to answer this exercise? It's due in two days, any help will be greatly appreciated.

Step-by-step explanation:

The leftmost line segment has a slope of -2 and (-1,-1)  is a point on the line.

Equation: y = -2x-3

middle line segment has a slope of 0 and  y-intercept of -2.

Equation:  y = -2

The rightmost line segment has a slope of 1.5. (5,0) is a point on the line.

y = 1.5(x-5) = 1.5x-7.5

c = 0.429t

step-by-step explanation:

the constant rate at which carlos harvests cassava is 35 minutes per 15 cassavas 15/35 = 0.429 cassava per minute

therefore, an equation that models the number of cassava (c) that harvest carlos in a time (t) is the following:

where t is the time in minutes.

this means that when 35 minutes have elapsed 15 cassava have been harvested, at 70 minutes 30 cassava have been harvested and so on.
