The expression 2t-U means, in words, "subtract U from twice the value of t".
So, if t = -3, twice this value would be -6.
Since U = 8, we have tu subtract 8 from -6, leading to
[tex]-6-8=-14[/tex]
Answer:
-14.
Step-by-step explanation:
Just replace the t and u in the given expression by -3 and 8:
2t - u
= 2*(-3) - 8
= -6 - 8
= -14.
