Answer:
53
Step-by-step explanation:
if f(a)= -11 the the equation is: 20-3(-11)
First, multiply -3 and -11:
20-3×(-11)
20+33
Now, add:
20+33= <u>53</u>
<u></u>

Answer:
x - 3y + z
Step-by-step explanation:
Terms are just names for objects inside the equation -- anything that isn't an operation. A coefficient the is the number a given term (variable) is being mulitpled by. In this case, -3 for y, and 1 for. x. We can deduce from this the start of the expression (x has no coeff. bc of multiplicative identity)
x - 3y
We know we are missing one term, and we also know that the third term cannot be constant, so it must be another variable. In this case I have chosen Z, in theory it shouldn't really matter but z is the best variable name in this case.
