Answer:

Step-by-step explanation:

abc = 1

We have to prove that,

$\frac{1}{1+a+b^{-1}}+\frac{1}{1+b+c^{-1}}+\frac{1}{1+c+a^{-1}}=1$

We take left hand side of the given equation and solve it,

$\frac{1}{1+a+\frac{1}{b}}+\frac{1}{1+b+\frac{1}{c}}+\frac{1}{1+c+\frac{1}{a}}$

Since, abc = 1,

$\frac{1}{c}=ab$ and c = $\frac{1}{ab}$

By substituting these values in the expression,

$\frac{1}{1+a+\frac{1}{b}}+\frac{1}{1+b+\frac{1}{c}}+\frac{1}{1+c+\frac{1}{a}}=\frac{1}{1+a+\frac{1}{b}}+\frac{1}{1+b+ab}+\frac{1}{1+\frac{1}{ab}+\frac{1}{a}}$

$=\frac{b}{b+ab+1}+\frac{1}{1+b+ab}+\frac{ab}{ab+1+b}$

$=\frac{1+b+ab}{1+b+ab}$

$=1$

Which equal to the right hand side of the equation.

Hence, $\frac{1}{1+a+b^{-1}}+\frac{1}{1+b+c^{-1}}+\frac{1}{1+c+a^{-1}}=1$

What is the slope and y-intercept of x/3= -y+2 and how?????

Katarina [22]

Subtract 2 from both sides

then you get -y equals 1/3x -2 so you have to flip the sign of the entire equation because you can’t have a negative line

so you get y = -1/3x + 2

the y-intercept is (0,2)

the slope is -1/3x (aka -x/3)

guajiro [1.7K]

Answer:

1.40 $ per pound.

Step-by-step explanation:

As we go by the statement given:

$2x + 3y = 7.20 ..... (1) \\and\\4x + 2y = 8.80 ...... (2)\\\\Now, multiplying \ the\ equation \ (1)\ by\ 2\ and\ then\ subtracting\ the\ equation\ (2)\ from\ it.\\(1) \times 2\\ \Rightarrow 4x+ 6y=14.40\\Now, subtracting\ the\ equation\ number (2)\\ \Rightarrow4x + 6y - 4x -2y = 14.40 - 8.80\\\Rightarrow 4y = 5.60\\\Rightarrow y = 1.40$ Hence, price for oranges is $1.40$ dollars per pound.
