Solve each system using a matrix

Serjik [45]

<u>ANSWER </u>

$x=\frac{1}{2}$ and $y=\frac{1}{4}$

<u>EXPLANATION</u>

Given;

$4x-12y=1$

and

$6x+4y=4$

The augmented matrix of the two linear equation is given by;

$\left[\begin{array}{ccc}4&-12|&-1\\6\:&\:\:\:4|&4\end{array}\right]$

We now perform row operations;

$\frac{1}{4}\times R_1 \rightarrow R_1$ .

This gives us

$\left[\begin{array}{ccc}1&-3|&\frac{-1}{4}\\6\:&\:\:\:4|&4\end{array}\right]$

$R_2-6R_1 \rightarrow R_2$

$\left[\begin{array}{ccc}1&-3|&\frac{-1}{4}\\0\:&\:\:\:22|&\frac{11}{2}\end{array}\right]$

$\frac{1}{22}R _2 \rightarrow R_2$

$\left[\begin{array}{ccc}1&-3|&\frac{-1}{4}\\0\:&\:\:\:1|&\frac{1}{4}\end{array}\right]$

$R_1+3R_2 \rightarrow R_1$

$\left[\begin{array}{ccc}1&0|&\frac{1}{2}\\0\:&\:\:\:1|&\frac{1}{4}\end{array}\right]$

Hence $x=\frac{1}{2}$ and $y=\frac{1}{4}$

HURRY IM ON A TIME LIMIT WILL MARK YOU BRAINLIEST

densk [106]

Answer:

45°

Step-by-step explanation:

Since WXYZ is a square, all of it's sides are equal. This means that triangle XYZ is an isosceles triangle (with two sides being equal), so ∠ZXY and ∠XZY are equal. ∠XYZ is right angle because it is in the corner of the square.

180 - 90 = 90

90/2 = 45

All I did was subtract ∠XYZ from 180° (which is the sum of every angle in a triangle), then divide that by 2 (because ∠ZXY and ∠XZY are equal).

The Great Pyramid of Giza is an example of a square pyramid and is the last

Verdich [7]

Answer:

The surface area of the pyramid is 466,137 squared cubits

Step-by-step explanation:

This is simply asking us to find the surface area of the square based pyramid with the given dimensions.

The first thing we need to know is the principle for finding the surface area of such pyramidal shapes. To get the surface area of a pyramid, we will have to add the base area to the area of the side faces ( lateral area)

The base area of the square based pyramid, will be the same as the area of a square which is = 453 cubits X 453 cubits = $205209 cubits^{2}$

The lateral area has already been given to us as 260,928 squared cubits.

The surface area of the pyramid is 260,928 + 205209 = 466137 squared cubits

Hence, the surface area of the pyramid is 466137 squared cubits
