amm18123 years ago
5 0

Step-by-step explanation:

12 - 1/2r = ( 13 - 3/2r ) - ( 1 - r )

r - 13/6 = ( 7r - 3/2 ) - ( 2/3 + 6r )

13r + 20 = ( 6r + 7 ) + ( 13 + 7r )

-12 + r = ( -8 - r ) + ( 2r - 4 )

Which statement is NOT true?
elena-s [515]
If x ^ 2 = 100, then x = 10.

 
For this case what you should know is the correct clearance of the following equation:
 x ^ 2 = 100

 We then have two possible solutions:
 x=+/- \sqrt{100}
 Rewriting we have:
 x=+/-10
 Therefore, the solutions are:
 x1=10

x2=-10
 Answer:
 
A statement that is NOT true is:
 
If x^2 = 100, then x = 10.

Let g(x, y) = cos(x + 5y). (a) Evaluate g(10, −2). g(10, −2) = (b) Find the domain of g. −1 ≤ x ≤ 1, − 1 5 ≤ y ≤ 1 5 −5 ≤ x ≤ 5,
RoseWind [281]

Answer:

since Cos(z) is a function defined for all z\in \mathbb{R}, then there is not restriction for x+5y, thus, the domain of g(x,y) is \mathbb{R}^2 and in interval notation is (-\infty,\infty)\times(-\infty,\infty)

Since Cos(x+5y)\in\mathbb{R} then the range of g(x,y) is the interval [-1,1].

Answer:

n = -2

Step-by-step explanation:

\frac{-5}{6}n-\frac{1}{6}=\frac{-1}{3}+\frac{11}{6}\\\\\frac{-5}{6}n=\frac{-1}{3}+\frac{11}{6}+\frac{1}{6}\\\\\frac{-5}{6}n=\frac{(-1)*2}{3*2}+\frac{11}{6}+\frac{1}{6}\\\\\frac{-5}{6}n=\frac{-2}{6}+\frac{11}{6}+\frac{1}{6}\\\\\frac{-5}{6}n=\frac{-2+11+1}{6}\\\\\frac{-5}{6}n=\frac{10}{6}\\\\n=\frac{10}{6}*\frac{6}{-5}\\\\n= -2
