Answer:
f(4) = 49
f(-3) = -35
Step-by-step explanation:
f(4) = 12(4) + 1 = 48 + 1 = 49
f(-3) = 12(-3) + 1 = -36 + 1 = -35
8(2r-3)-r=3(3r+2)
16r-24-r=9r+6
16r-r-9r=6+24
6r=30
R=30÷6
R=5
The subset of A is B = {1, 2} and the proper subset of A is C = {1,2,3,4}
<h3>How to create the Subset and Proper Subset of the set?</h3>
The set is given as:
A = {1,2,3,4}
Subsets of a set are sets that can be found in another set
An instance of this is
B = {1, 2}
Because all the elements of set B are in set A
Proper subsets of a set are sets that contain the exact elements found in another set
An instance of this is
C = {1,2,3,4}
Because set C and set A have the same elements

Answer:
65 degrees.
Step-by-step explanation:
It's hard to explain, but I'll try:
The outside of the first two angles is 105 and 140. Half a whole angle is 180. So, you do
180-140=40. The inside is 40.
And then 180-105=75.
Then you add the two and subtract them from 180:
40+75= 115
180-115=65
Voila!
