Write and equation in slope intercept form to model the situation. A candle is 8 inches tall and burns at 3/4 inch each hour.

The equation that models the situation is

Step-by-step explanation:

Equation of a line:

The equation of a line, in slope-intercept formula, has the following format:

In which m is the slope(how much y changes when x changes by 1 unit) and b is the intercept, which is the value of t when x = 0.

A candle is 8 inches tall and burns at 3/4 inch each hour.

Using t as number of hours and y as the height.

Initial height of 8 inches, that is, when , so

Burns at 3/4 inch each hour.

That is, the height decreases by a rate of 3/4 inch each hour, so

So

answer: first option i.e. 'a' is correct.

step-by-step explanation:

since we have given that

number of minutes to wrap a small gift box = 4 minutes

we need to find the number of gifts to be wrapped in 5 minutes

since there is a direct variation, as the number of minutes will increase with   number of gifts to be wrapped.

so, let the number of gifts to be wrapped in 5 minutes be x.

so, it becomes,

hence, first option 'a'   is correct.

answer is 33
