If you mean 2x -3y = 6 then it is true and so is (3, 0)
x is 45.
Without any equality signs the given terms can't be considered to be equations.
This website isn't equipped to reproduce most mathematical symbols in the questions. I'll see if I can translate. 2x + 3(x - 10) = 45 2x + 3x - 30 = 45 5x - 30 = 45 5x = 75 x = 15 Check it. 2(15) + 3(15 - 10) = 45 30 + 15 = 45 It checks.
It is f(x) = -x2 or (-x)2, whichever you intended.
The answer is B.
If you mean: 3x -7 +4x = 28 then the value of x works out as 5
x is 45.
It depends what 6(p - 4) - 30p is supposed to equal. Substituting p = -1, gives: 6((-1) - 4) - 30(-1) = 6×-5 - 30×-1 = -30 + 30 = 0 Only if 6(p - 4) - 30p = 0 is p = -1 a solution. Otherwise it is not a solution.
It is -137.8
The browser used for posting questions on this site is rubbish. It is quite useless for mathematics since it strips out most symbols so that we cannot tell what the question is meant to be.If the equation is 6y - 8 = 28 then the answer is y = 6.

(n - 3)(n - 5) = n² - 8n + 15
It is 9x + 2.
