On a cold winter day the temperature was -1 below zero. at night the temperature be dropped 4. what was the final temperature

-1 + -4 = -5 below zeroIf the temperature is -1 + 4 the temperature would be 3 degrees (-1+4=3)

Step-by-step explanation:

If the temperature is -1 + -4 = -5 below zero (adding two negatives equal a negative number).

If the temperate is -1 + 4 = 3 (+4-1=3) The number is positive because it is larger than the negative number.

i found two solutions,   n = 2 • ± √3 = ± 3.4641

step-by-step explanation:

b. y = 4x - 2

step-by-step explanation:

to find a parallel equation to an equation, make sure both equations have the same slope but different y-intercepts.

y = 4x + 1

4 = slope

1 = y-intercept

y = 4x - 2

4 = slope

-2 = y-intercept

they both have the same slope but different y-intercepts, so, b. is the correct answer.

and to check your work, you can graph both equations. : )
