Apples are $0.68 and peaches are $0.42.

To find these values, we need to write and solve the following system of equations.

6x + 9y = 7.86
4x + 5y = 4.82

Multiply the first equation by 2 and the second by -3.

12x + 18y = 15.72
-12x - 15y = 14.46

Add the equations together.
3y = 1.26
y = 0.42

Sub in 0.72 and solve for x in either equation and you will get x = 0.68.

Given :

A function f(x) for different range of x.

To Find :

The value of f( -3 ) .

Solution :

We have to find the value of function at x = -3.

Now, in the given figure -3 lies in range x ≤ -2 and definition of function at that range is :

f(x) = \dfrac{2}{x}

So, putting value of x = -3 in above equation, we get :

f(-3) = \dfrac{2}{-3} \\\\f(-3) = \dfrac{-2}{3}

Hence, this is the required solution.

Answer:

Number of permutations = 5040

Step-by-step explanation:

We are given the word 'INNOVATIVE', that has total 10 letters.

Now, we are asked to form words using exactly 4 letters at a time i.e. out of 10 letters we are using 4.

Therefore, the number of permutations that can be formed using 4 letters are = P(10,4)

i.e. 10_{P_{4} }

= \frac{10!}{(10-4)!}

= \frac{10!}{6!}

= \frac{10*9*8*7*6!}{6!}

= 10*9*8*7

= 5040
