So when x = -1, you just substitute the variable x to -1.
"4x" means 4 times x, so when x is replaced to -1, that would be 4 times -1.
f(-1) = 4(-1) = -4
So the value of function at x = -1 would be -4.
Hope this helps.

v=vanilla
c=chocolate
A.
4v+c=45
v+c=27
b.
multiply 2nd equation by -1 and add to first
4v+c=45
-v-c=-27 +
3v+0c=18
3v=18
divide both sides by 3
v=6
sub bac
v+c=27
6+c=27
minus 6
c=21

Step-by-step explanation:
True, because a parallelogram is a four-sided rectangular figure with opposite sides parallel. This is a way to describe a rectangle as well. The only difference is that rectangles must have 90 degree angles, but it is possible for a parallelogram to have 90 degree angles as well. This also means that all rectangles are technically parallelograms as well.
