Answer:
36π mi
Step-by-step explanation:
Area of a circle = πr²
Diameter = 12 mi. Therefore, radius=12/2 = 6 mi
πr²
π x (6)²
π x 36

-1+5x
You combine like terms:
Here there are two different ones.
the number without the variable (the 1s) and the one with the variable (5x)
All you have to do is combine them:
1+(-1)+(-1) = 1-1-1 = -1
5x = 5x
So, the answer would be -1+5x
Hope this helps :D
Y=1
To get it, you use the method of substitution. So you swtich the top y by the equation of the bottom=-3x+6=-7x+10. You first add 7x to each side=4x+6=10 then you minus 6 from each side=4x=4 which is 1
