The temperature at dawn one morning was –6 °C. It increased at a constant rate of 2 °C per hour after that. Which equation describes t, the time in hours since dawn, in terms of C, the temperature in degrees Celsius?

Step-by-step explanation:

Let's first write the data you have in an equation form:

. When t = 0, at dawn, you get -6°C so we're good. But you've ben asked the inverse relationship, so let's solve for t instead.

Last two are both viable solution, only difference is in form. I do prefer the last option since it makes it easiest at a glance to answer to the question "at what time there's a temperature of 0°C?"

add all the numbers and check the ones place.

the answer is 486. as the ones place is more than 4, the estimation will be the next 10 ie, 490

step-by-step explanation:

84/3.5 = 24
