Answer:

$x = -4, y =-8$ is the solution to the system of equations.

Step-by-step explanation:

Given the system of equations as:

$y= \dfrac{1}{2}x-6$

and

$x =-4$

To find:

The solution to the system of equations = ?

Solution:

Here, we are given two equations and two variables i.e. $x$ and $y$ .

So, we can solve the system of equations for the values of $x$ and $y$ .

Let us first consider the 2nd equation.

$x =-4$ we already have the value of $x$ .

Now, let us put the value of $x$ in the 1st equation to find the value of $y$ .

$y= \dfrac{1}{2}x-6$

$\Rightarrow y= \dfrac{1}{2}\times (-4)-6\\\Rightarrow y= -\dfrac{1}{2}\times 4-6\\\Rightarrow y= -2-6\\\Rightarrow \bold{y =-8}$

So, the solution to the system of equations is:

$x = -4, y =-8$

You have 1 blue suit, 2 black suits, and 1 brown suit, You also have 2 blue ties, 3 red ties, and 3 pink ties. What is the proba

tia_tia [17]

The probability that you pick a striped shirt AND a blue suit is 1/4 AND a pink tie is 3/8.

According to the statement

Number of blue suit = 1

Number of black suit = 2

Number of brown suit = 1

Number of blue ties = 2

Number of red ties = 3

Number of pink ties = 3

Now we find the probability by its formula

Probability that picked suit is blue = blue suits/ total number of suits

Probability = 1/4

Now,

Probability that picked tie is pink = Pink tie / total number of ties

Probability = 3/8

So, The probability that you pick a striped shirt AND a blue suit is 1/4 AND a pink tie is 3/8.
