<em>Try the answers</em>
Of the offered choices, the only ones that go through the given point are ...
... x = 2
... y = -5
The latter is horizontal and parallel to y = 7, so is not the choice you want. The appropriate choice is ...
... A) x = 2
_____
<em>Figure out the answer</em>
The given line is horizontal, so the line you want is vertical—of the form ...
... x = constant
The constant must be chosen so the line will go through a point with x=2. It should be obvious that the constant must be 2.
... x = 2 is perpendicular to y = 7 and goes through (2, -5).

Answer:
x ≠ 3
Step-by-step explanation:
In any case, the domain is restricted to values of the variable for which the function is defined. The value 1/0 is not defined, so the variable cannot allow the denominator to be zero. The denominator x-3 will be zero for x=3, so that value of the variable cannot be in the domain.
The domain is all real numbers except x=3.

<em>Additional comments</em>
It is useful to become familiar with the domains of different functions. As we saw above, the reciprocal of 0 is undefined. The square root of a negative number is undefined. The log of a non-positive number is undefined. Trig functions are defined everywhere, but their inverse functions are not. Polynomial functions are defined everywhere, but ratios of polynomials have the same restriction on denominators that we see above.
The log of this is 15 because I multiplied 5•3 that gave me 15 so the answer to this problem is 15
Answer:
the answer is C :)
Step-by-step explanation:
X=2y
2x+5y=9
substitute the x=2y into the second equation
2(2y)+5y=9
multiple the 2y by 2. 4y+5y=9
combine like terms. 9y=9
divide the 9 out from both sides. y=1
plug the y back into the first equation
x=2(1)
multiply. x=2
your answer is: x=2
y=1
