Two-variable equations as models
example: miranda has 55 feet of fencing. she wants to use all the fencing to
create a rectangular garden. the equation 21 + 2w = 55, where t is the length of
the garden and w is the width, models the scenario. this equation can be used to
find one dimension of the garden if the other dimension is known.
think about constraints:
each side must be
than 0.
each side must be
then 27.5.
each side must be greater than a
inches.

answer: b.

step-by-step explanation:

the y coordinate for point b is 0, and answer b is the only one with that y coordinate.

step-by-step explanation:

chemists are often responsible for designing a chemical reaction and analyzing the products obtained from it. one significant part of designing a chemical reaction is determining the amount of each reactant that is needed and the amount of each product that will be produced. in order to do so, chemists use stoichiometry, the quantitative relationships between reactants and products.
