I think you are asking if -8x ≥ 40, find x. What we do here is we divide negative 8 by both sides. This gives us x ≥ 5. BUT, we have to be careful!!!! When we divide an inequality on both sides by a negative number, we have to switch the sign. Thus, our answer is x ≤ 5.
Answer:
-2, -3, 17, 25.
Step-by-step explanation:
It's any number before a variable.
A)
Take <span> Newton’s law </span><span>of cooling as a basis and make a transformation :
</span>From :
to :
Then solve :
And the result :
b) The easiest way how you can find the temperature of the engine 30 minutes after you turn it off :
Here is the solution in the nearest tenth of a degree : <span>T = 80.3℉ </span>
Coefficient is the correct answer
Check the picture below
notice, the angle at vertex P, is inscribed in the circle, and intercepting arcQR.
