7.) (x, y) —> (1/2*x, 1/2*y)
Answer:
12 divided by 48
Step-by-step explanation:
12 divided by 48 is 4 so u need to divide and she what you get and then
that answer and multiply it by 4 and see if you got the same answer and if you did then it is correct unless you have worked it wrong always try your best and work hard
The answer
mathematics rules tell that
if A and B are two statements that are equivalents, that is also called biconditional statement, or " if and only if " statement
the general signification of <span>biconditional statement and its converse is:
if A, then B and if B then A (the converse), A and B are equivalent statements
</span><span>["If a natural number n is odd, then n2 is odd" and its converse ] does mean
</span><span>A natural number n is odd if and only if n2 is odd.
the answer is B</span>
Answer:
140 liters will remain after 10 mins
Step-by-step explanation:
The easy way is just multiply the amount lost per min by the number of mins.
sqrt (5x - 9) - 1 = x
sqrt(5x - 9) = x + 1
Square both sides:_
5x - 9 = x^2 + 2x + 1
x^2 - 3x + 10 = 0
(x - 5)(x + 2) = 0
x = 5 or -2.
Lets look for for any extraneous solutions:-
x = 5 ; sqrt (5*5-9) - 1 = sqrt16 - 1 = 3 and x = 3 (right hand side of equation)
so x = 5 is a solution
x = -2: sqrt(5*-2 - 9) - 1 = sqrt (-19) - 1 and x = -2 so this is extraneous
Answer:- One solution x = 5
