Jorge used a graph to determine a solution to the following system of equations:

x + y = 92 and y = 3x – 4

Jorge’s answer is (67, 25). Is he correct? Explain how to check if his solution is correct without using a graph.

The answer is in the answer section and it is the sample response

step-by-step explanation:

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.
