Answer:
T4 = -2°F
Step-by-step explanation:
Given the following data;
Current temperature = 10°F
Constant, K = 3°F
Time, t = 4 hours
In four (4) hours, we have;
T = kt
Substituting into the equation, we have;
T = 3 * 4
T = 12°F
T4 = current temp - new temp
T4 = 10°F - 12°F
T4 = -2°F
Therefore, the temperature it will be in 4 hours is - 2°F.

Step-by-step explanation:
I do now know what this is about
Answer:
0.33-0.25= 0.08
then 1999-1989= 10
lastly 0.008
Step-by-step explanation: so the average rate of
change in postage in<em><u> cents</u></em> per year. is 0.8 of a cent. or 0.008 of a dollar.
<span>if you're finding the x intercept, y is ALWAYS 0, so in this, you can just get rid of the -4y because you know that it's 0, so you're left with 2x=12 divide by 2 on both sides so you find x intercept is (6,0) on the graph
the y works the same way, if you're looking for the y, you know that the x is zero, so you're left with -4y=12, divide by -4y on both sides and you end up with the y intercept being (0,-3)
x int.= (6,0)
y int.= (0,-3)
by the way, when it's written like that, it's called standard form, so to find the intercepts on 2x=12+4y, you'd have to convert it into standard form (Ax=By=C) so you subtract 4y on both sides to make it 2x-4y=12, and then once you have it like that you can do the math to find the y and x intercepts.
