Answer:

Step-by-step explanation:

Don't mind the 
6x-18 14x+38
subtract the 6 from the 6 and the 14 which will give you: then add the 18 to the the 18 and the 38
8x = 56
then divide 8/8 which is zero and 8/56 which equals 7 so ur answer is x=7

To find the value of q, we need to find d(-8). Put another way, we need to find the value of d(x) when x = -8





So this means q = 0. Note that -0 is just 0.
===========================================
The value of r will be a similar, but now we use f(x) this time.
Plug in x = 0





Therefore, r = 2.
===========================================
For s, we plug x = 10 into f(x)





So s = 3.
===========================================
Finally, plug x = 10 into d(x) to find the value of t





A shortcut you could have taken is to note how d(x) = -f(x), so this means
d(10) = -f(10) = -9 since f(10) = 9 was found in the previous section above.
Whichever method you use, you should find that t = -3.
===========================================
<h3>In summary:</h3><h3>q = 0</h3><h3>r = 2</h3><h3>s = 3</h3><h3>t = -3</h3>
