Ihave more questions

the cost (in dollars) of making n birthday cakes is represented by c = 24n + 35. how many birthday cakes are make when the cost is $395? explain your reasoning.

again, for me out.

The slope of a line is -1/2 . what is the slope of a line that is parallel to it? a. 1/2 b.2 c. -1/2 d. -2

Icould really use some with this question.

Arefrigeration system at your company uses temperature sensors fixed to read celsius (°c) values, but the system operators in your control room understand only the fahrenheit scale. you have been asked to make a fahrenheit (°f) label for the high temperature alarm, which is set to ring whenever the system temperature rises above –10°c. what fahrenheit value should you write on the label?
