Answer:

b (x, x - 3, 0)
d Infinite Solutions

Step-by-step explanation:

1. A graphing calculator or any of several solvers available on the internet can tell you the reduced row-echelon form of the augmented matrix ...

$\left[\begin{array}{ccc|c}2&-2&-1&6\\-1&1&3&-3\\3&-3&2&9\end{array}\right]$

is the matrix ...

$\left[\begin{array}{ccc|c}1&-1&0&3\\0&0&1&0\\0&0&0&0\end{array}\right]$

The first row can be interpreted as the equation ...

x -y = 3

x -3 = y . . . . . add y-3

The second row can be interpreted as the equation ...

z = 0

Then the solution set is ...

(x, y, z) = (x, x -3, 0) . . . . matches selection B

__

2. The second equation is 2 times the first equation, so the system of equations is dependent. There are infinite solutions.

A her of 40 horses has 9 white and some black horses. What is the ratio of white to black horses?

solmaris [256]

Answer:

The number of white horse to white horse is 9 : 31

Step-by-step explanation:

Given as :

The Total number of horses = 40

The number of white horses = 9

Let the number of black horses = x

So, x + 9 = 40

Or x = 40 - 9 = 31

∴ The number of black horses = 31

Now, The ratio of while to black horses = number of white horse : number of black horse

Or, number of white horse : number of black horse = 9 : 31

Hence The number of white horse to white horse is 9 : 31 Answer

What is the value of x?

Juliette [100K]

Answer:

94

Step-by-step explanation:

The triangle is split into two similar triangles. They have the same shape but not the same size. To solve, write a proportion to find KY.

$\frac{95.2}{168}=\frac{34}{KY}$

Cross multiply to solve for KY.

95.2(KY) = 168(34)

95.2KY = 5,712

KY = 60

Add KY to 34 to find x.

60 + 34 = 94.
