Answer:
-24
Step-by-step explanation:
Exponents go first. 4^2=16. 2^3=8. Next multiplication. 5*8=40. Now subtraction. 16-40=-24
Convert to the standard form:-
x^2 + 14x + y^2 - 6y = -42
(x + 7)^2 - 49 + (y - 3)^2 - 9 = -42
(x + 7)^2 + (y - 3)^2 = -42 + 49 + 9 = 16
r^2 = 16 so r = 4 and the diameter = 2*4 = 8 Answer
Answer:
Both fractions are already in the simplest form.
Portuguese translation: Ambas as frações já estão na forma mais simples.
Answer: False
Step-by-step explanation:
As time goes by, the resale value of a computer tends to drop because it tends not to function as properly as it did before, and the quality of new computers on the market drives the price of older computers down. So you can expect that as the amount of time increases, the resale value will decrease, resulting in a negative correlation
