Well, i think you just need to move the 2 matches on the top and the bottom of the number 0 and put it after the number 8
This way, you will change the number from
5 0 8
into
5 1 1 8 1 1
hope this helps
We can set this problem up as an algebraic equation, which we can then solve to find our answer.
We start at -3. So we can start our equation with that:

However, this doesn't represent any change in temperature, just that we start at -3. To show change, we will use the variable
, where
stands for the number of hours. Each hour accounts for a change of -2.5 in degrees, meaning that we must multiply our
by -2.5. We can now add this term into our equation:

We are trying to find when we will reach -18 degrees, so we will set our entire equation equal to -18 and solve:



It will take us 6 hours, or choice A.
We are asked to find z = g0f or what is the same:
z = g (f (x))
That is, we must introduce the function f (x) within the function g (x)
So, we have
f (x) = 3x-9
g (x) = x ²
Therefore we have the following function
z = (3x-9) ²
Finally (g0f) (5) = (3 (5) -9) ²
(g0f) (5) = 36
Answer:
the desired range is 2 < t < 12.
Step-by-step explanation:
If the third side is 12 (the sum of 5 and 7), we don't really have a triangle, since the 5-unit and 7-unit sides add up to 12 and lie on the third side (of length 12).
Since triangle ABC is acute, all its angles are between 0 and 90 degrees. So the third side can be 12 but not greater. The smallest possible length of the third side is 2, since 5 + 2 = 7.
Thus, the desired range is 2 < t < 12.
