What is | -7.9 ? help

Mathematics
1 answer:
Tamiku [17]3 years ago
3 0
I think you mean |-7.9| which is the absolute value of 7.9
Absolute value just means how far away it is from zero on a number line.
So the value is always positive. So the positive of -7.9 is 7.9
|-7.9|= 7.9
Good luck!

use coordinate notation to write the rule that maps each preimage to its image. The identify the transformation and confirm that
Ymorist [56]

The <em>rigid</em> transformations used for each figure:

  1. Figure 5 - Reflection around x and y axes: (x, y) → (- x, - y)
  2. Figure 6 - Horizontal and vertical translations: (x, y) → (x + 1, y - 2)

<h3>What transformation rules do create the resulting images?</h3>

In this question we must determine what kind of <em>rigid</em> transformations generates each image. <em>Rigid</em> transformations are transformations applied on geometric loci such that <em>Euclidean</em> distance is conserved. Now we proceed to determine the transformation rule for each case:

Figure 5 - Reflection around the x-axis followed by reflection around the y-axis.

(x, y) → (- x, - y)

Figure 6 - Translation one unit in the +x direction and two units in the -y direction.

(x, y) → (x + 1, y - 2)

4x2 + 9y2 = 72<br> 2x - y = 4<br><br> Which of the following is a solution to the system shown?
Ede4ka [16]
If you would like to solve the system of equations, you can do this using the following steps:

4x^2 + 9y^2 = 72
2x - y = 4 ... 2x - 4 = y
_________
<span>4x^2 + 9y^2 = 72
</span><span>4x^2 + 9 * (2x - 4)^2 = 72
</span>4x^2 + 9 * (4x^2 - 16x + 16) = 72
4x^2 + 36x^2 - 144x + 144 = 72
40x^2 - 144x + 144 - 72 = 0
40x^2 - 144x + 72 = 0
10x^2 - 36x + 18 = 0
5x^2 - 18x + 9 = 0
(5x - 3) * (x - 3) = 0
1. 5x - 3 = 0 ... 5x = 3 ... x = 3/5
2. x = 3

<span>1. y = 2x - 4 = 2 * 3/5 - 4 = 6/5 - 20/5 = -14/5
2. y = 2x - 4 = 2 * 3 - 4 = 6 - 4 = 2

1. (x, y) = (3/5, -14/5)
2. (x, y) = (3, 2)

The correct result would be </span>(3/5, -14/5) and <span>(3, 2).</span>

BRAINLIEST TO FIRST CORRECT ANSWER!!
sineoko [7]

Answer:

57\:\mathrm{km}

Step-by-step explanation:

Since the question implies his truck travels at a constant distance per gallon, we can set up the following proportion to find how much father his truck can go.

Let x represent how much farther his truck can go, in kilometers:

\frac{2}{76}=\frac{1.5}{x}

Cross-multiplying, we get:

2x=76\cdot 1.5,\\x=\frac{76\cdot 1.5}{2}=\boxed{57\:\mathrm{km}}
