Thus, the final answers are 1 and -1/8.
Answer:
A = 100 pi cm^2
Step-by-step explanation:
A = pi(r^2)
A = pi(10^2)
A = pi(100)
A = 314.16 '
Convert to pi units.
314.16 ---> 100pi cm^2
Answer: 5x - 2y = 8
y+1=5/2(x-2)+2
multiply the each side by 2 to get rid of the fraction
2 (y+1) = (5/2 (x-2) +2 )2
2y+2=5(x-2)+4
now distribute the 5
2y+2=5x-10+4
subtract the two from each side
2y=5x-10+4-2
add like terms
2y=5x-8
subtract 5x from each side
2y-5x=-8
multiple the whole equation by -1 to make the 5x a positive
-2y+5x=8
hope this helps!
