Answer:
13
Step-by-step explanation:
if you only have $130 to spend where everywhere is $10 then you do 130/10 in the calculator and you get 13.
The answer is 100 before the 1 is on the hundreds place and there are no decimals
Get the number without the X and you are deciding by that number for example 5x=10 your going to decide by 5 your 5 cancels on the left and u devise by 5 on the right as well and you get x=2
What do you need to figure out. i am happy to help
Step-by-step explanation:
x² + y² + 2x + 6y = 39
( x + 1)² - 1 + ( y + 3)² - 9 = 39
( x + 1)² + ( y + 3)² - 10 = 39
(x + 1)² + (y + 3)² = 49
radius= √49 = 7
center = ( -1 , -3)
x² + y² - 4x - 2y + 1 = 0
(x - 2)² - 4 + (y - 1)² -1 + 1 = 0
(x - 2)² + (y - 1)² = 4
radius = √4 = 2
center = (2 , 1)
