Answer:
Pi is equal to 3.14...
it is ratio of a circle's circumference to its diameter.
1 is reflection
Basically u got to look at what happens to the original shape
Step-by-step explanation:

For this parallelogram to exist least value of x should be 4.
Because if x = 3
(x - 3)= 3 - 3 =0
Thus width of parallelogram would become zero as a result area of parallelogram would become zero i. e. Parallelogram won't exist.
Answer:
Step-by-step explanation:
To properly apply the substitution method, it will be better for us to rearrange the system of equations to have similar variables on the same side


We can simply evaluate equation 1 to have

y = -20
From the first equation alone, we can evaluate the value of y as -20. This is because only one unknown is present in equation one, hence a single equation is sufficient enough to evaluate it. If to unknowns were present, the two equations would have been utilized to evaluate the solution.
D
The reason is because well first of the plotted dot is filled in with means that x needs to be less then or equal too so to represent that you put the line under the less then symbol and none of the other options have that exact symbol
The arrow is going to the left this is stating that x needs to be less than -2
If it’s wrong then I apologize because I don’t really remember this
