Answer:An inverse operation are two operations that undo each other addition and subtraction or multiplication and division. You can perform the same inverse operation on each side of an equivalent equation without changing the equality. This gives us a couple of properties that hold true for all equations i guess a little bit of fraction might help if im right idk but forget the fraction part just read the other.
Step-by-step explanation: thats all i got.
Answer:
Step-by-step explanation:
Slope of the line through (0,3) and (2,5) = (5-3)/(2-0) = 1.
Equation of line: y = x+3
When x=3, y=6
(3,n) = (3,6)
Answer:
Never
Step-by-step explanation:
To solve the equation using complete square method we proceed:
z^2-19z=66
but
c=(-b/2a)^2
c=(-19/2)^2
c=361/4
thus:
z^2-19z+361/4=66+361/4
factoring the LHS we get:
1/4(2z-19)^2=625/4
(2z-19)^2=625
getting the square root of both sides we get:
2z-19=+/-25
2z=+/-25+19
2z=44 or -6
z=22 or -3
Answer: z=22 or z=-3
