Christopher spends a winter day recording the temperature once every three hours for science class. At 9 am, the temperature was -10.3°F. Between 9am and noon, the temperature rose 9.6°F. Between noon and 3pm, the temperature went up 15.8°F. Between 3pm and 6pm, the temperature went down 14.2°F. What was the temperature at 6pm?

range is infinite on both x and y axis positive and negative

step-by-step explanation:

if y=4x then you will substitute 4x in for y in the second equation.

8x + 4x = 18 combine like terms

12x = 18 divide by 12 on both sides

x = 18/12 or 3/2

now replace x in the first equation with 3/2 to get

y = 4 3/2

y = 6

the answer is a

(3/2,6)

hope that .

brainliest is always apprectiated

0.4 liters = 400 milliliters (multiply the volume value by 1000 and it give you the answer). hope this ! ^-^
