Answer:
f(-4) = -18
Step-by-step explanation:
f(-4) means x = - 4
So Plug in x = - 4 into f(x) = 3x - 6
f(-4) = 3(-4) - 6
= -12 - 6
= -18
So
f(-4) = -18
We could do it by first writing
so that
and since 
, we have
# # #
Alternatively, we can just compute the product and take it mod 4:
and so we get the same result of 1.
Answer:
Delia started working at 9:50 A.M.
Step-by-step explanation:
We are given that:
Delia worked for 45 minutes on her oil painting.
She took a break at 10:35 A.M.
We have to determine at what time Delia start working on the painting.
35 minutes before 10:35 A.M. is 10 A.M.
Now, 45-35=10 minutes are left
now 10 minutes before 10 A.M. is 9:50 A.M.
Hence, Delia started working at 9:50 A.M.
