Yesterday the temperature at noon was 27°F. By midnight, it had gone down by 29.9°F. What was the temperature at midnight? HELP HELP HELP

This is a basic subtraction question and is indicated by the use of the words "it had gone down by."

= -2.9 degrees Fahrenheit

answer:

your answer is: c. 196 7/8 in^3.

the equation of the parallel line would be y = 2x + 9

step-by-step explanation:

to start we need to find the slope of the original line. we can do that by looking at the coefficient of x, which is 2

since the slope of the original line is 2 and parallel lines have the same slope, we know the new line will also have 2 slope. now we can use that along with the point given in point-slope form to get the find equation.

y - y1 = m(x - x1)

y - 5 = 2(x + 2)

y - 5 = 2x + 4

y = 2x + 9
