What are the solutions for x when y is equal to 0 in the quadratic function. y=x^2-25a. x = 5 b. x = −20 or x = 5 c. x = 5 or x = −5 d. x = 10 or x = −15

yes

step-by-step explanation:

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.
