The driver of a semitrailer truck makes regular deliveries of ice cream to a grocery store. the weight of a semi
when it is empty is 16 tons. each delivery includes at least 14 tons of ice cream. the delivery route includes a
bridge with a weight limit of 60 tons.
sometimes, the semi delivering ice cream and an empty semi pass each other on the bridge, going in opposite
directions. what weight loads can the semi hold to be safe on the bridge when considering the passing
another empty semi on the bridge while making a delivery?
translate the problem from words into a compound inequality.

first anwser choice.

step-by-step explanation:

the greater/less or equal to symbol (> or < with the line at the bottom) is a closed/filled in circle.

-5c + 2 _< _27

subtract from both sides by 2

-5c _< _ 27

divide both sides by -5

c _< _ 5.4

flip the inequality sign

c _> _5.4

the only possible answer that would match the simplified inequality is the first answer choice

step-by-step explanation:

we have

using a graphing tool

see the attached figure

this is a quadratic equation (vertical parabola) open up

the vertex is a > vertex

the domain of the function is all real > interval (-∞,∞)

the range of the function is the > [-6.125,∞)

the function has two x->   and

the function is increasing over the > (0.25,∞)

the function is decreasing over the > (-∞,0.25)

the ordered pairs for the given function are of the form
