As the weight of the purchased items increases, the shipping charges increase, as shown in the table below. Assuming only positive domain values, which statement is true of the graph that represents the total cost, y, in dollars fo shipping items that weigh x ounces?

a. the graph is discontinuous at x = 5, x = 10, and x = 15

Step-by-step explanation:

edge 2021

(:

for this case we have by definition, if two lines are perpendicular, then the product of their slopes is -1.

then, given the following line:

so,

we are looking for m_ {2}:

then, the line is given by:

we find "b" replacing the given point:

finally, the equation is:

option c

the correct answer option is (2x-3)(2x+3).

step-by-step explanation:

we are given the following expression and we are to factorize it:

we are to find such factors that when multiplied they give a result of 36 (9 x 4 = 36) and when added they give a result of 0.

the two such factors of 36 are negative six and postive six.

factorizing the given expression to get:

therefore, the correct factorization of is (2x-3)(2x+3).
