From midnight to 9:00 am, the temperature rose 0.80.8°C each hour. If the temperature at midnight was -5−5°C, what was the temperature at 9:00 am?

yeah 0.81 each hour so what is that + it 9 times so its 43.664F or 6.48C

Step-by-step explanation:

1.4

2.3

step-by-step explanation:

the formula for the constant of variation is

y= kx

divide each side by x

y/x =kx/x

y/x =k

we know a and y

1.   y/x = k

4/1 =4

check the other values to make sure they are the same

8/2 = 4   12/3 =4   and 16/4 =4  

the constant of variation is 4

2.   y/x = k

3/1 =3

check the other values to make sure they are the same

6/2 = 3   9/3 =3   and 12/4 =3  

the constant of variation is 3

uhhh idk u yolo?
