The best answer to this question is to subtract 4 from both sides. This isolates the square root and sets you up for squaring both sides of the equation.
Answer:
B.
Step-by-step explanation:
Because you have to multiply 6y by 2 that is 12y and you have to multiply -4 by 2 that is - 8, you put it together and it's 12y - 8.
Answer:
A. F(x) = 1/(x +2)²
Step-by-step explanation:
The asymptote at x = -2 tells you that x -(-2) = x +2 is a denominator factor. The fact that the function has the same sign on both sides of the asymptote tells you that factor has even degree.
Of the choices listed, the appropriate one is ...
F(x) = 1/(x +2)²
Answer:
x=6, y=-6
Step-by-step explanation:
-4x-2y= -12
4x+8y= -24
comparing both equations and crossing out both 4x we get
6y= -36
y= -36/6
y= -6
now for finding x, take any one of those equations
we'll take 4x+8y= -24 for now other one would work too
4x+8(-6)= -24 (as y= -6)
4x-48= -24
x= 24/4
x= +6
Answer:
15 and 27
Step-by-step explanation:
let the smaller number be n then the larger number is n + 12 and
n + n + 12 = 42, that is
2n + 12 = 42 ( subtract 12 from both sides )
2n = 30 ( divide both sides by 2 )
n = 15
and n + 12 = 15 + 12 = 27
The 2 numbers are 15 and 27
