Once upon a time, there was a former whose family raised pigs and chickens. One morning, the farmer's wife looked into the barny

Fed [463]

Using a system of equations, it is found that:

There are 8 chickens in the yard.

There are 16 pigs in the yard.

-----------------------------------------

This question is solved using a system of equations. I am going to say that:

x is the number of chickens.

y is the number of pigs.

-----------------------------------------

A chicken has 1 head, as do a pig.
There are 24 heads.

Thus:

$x + y = 24 \rightarrow y = 24 - x$

-----------------------------------------

A chicken has 2 feet.
A pig has 4 feet.
In total, there are 80 feet.

Thus:

$2x + 4y = 80$

-----------------------------------------

Number of chicken:

Since $y = 24 - x$

$2x + 4y = 80$

$2x + 4(24 - x) = 80$

$2x + 96 - 4x = 80$

$2x = 16$

$x = \frac{16}{2}$

$x = 8$

There are 8 chickens in the yard.

-----------------------------------------

Number of pigs:

$y = 24 - x = 24 - 8 = 16$

There are 16 pigs in the yard.

Determine all values of h and k for which the system S 1 -3x - 3y = h -4x + ky = 10 has no solution. k= ht

Lana71 [14]

Answer:

$h\neq 7.5$

k = -4

Step-by-step explanation:

Given system of equations are,

-3x-3y = h

-4x + ky = 10

We have to find the values of h and k such that system of equations has no solution.

The standard form of system of equation in two variables can be given by,

$a_1x+b_1y+c_1=0$

$a_2x+b_2y+c_2=0$

And condition for the system of equations has no solution is given by,

$\dfrac{a_1}{a_2}=\dfrac{b_1}{b_2}\neq \dfrac{c_1}{c_2}$

So, by comparing the standard form of equations with given equations, the condition such that system has no solution can be written as,

$\dfrac{-3}{-4}=\dfrac{-3}{k}\neq \dfrac{h}{10}$

$=>\dfrac{-3}{-4}=\dfrac{-3}{k}$

=> k = -4

and $\dfrac{-3}{-4}\neq \dfrac{h}{10}$

$=>\ \dfrac{-3\times 10}{-4}\neq h$

$=>\ h\neq \dfrac{30}{4}$

$=>\ h\neq 7.5$

So, the value of h and k for above given system of equations is

$h\neq 7.5$ and k = -4.
