<span>When a number is negative,it's opposite is also it's Additive Inverse.

For example -2, it's opposite is = +2

And +2 is the additive inverse of -2, because -2 + (+2) = -2 + 2 = 0

And if both numbers add up to 0, they are additive inverse of each other.

Which vector best describes the translation below?

Nimfa-mama [501]

<h3>Answer: Choice A) <9,0></h3>

Explanation:

Focus on one of the points in the figure on the left. Let's say we go for the upper left corner point (-7, 4)

Notice it moves to the corresponding image point (2,4). It has shifted 9 units to the right to follow the translation rule $(x,y) \to (x+9, y)$ . We've added 9 to the x coordinate, and the y coordinate stays the same.

This notation can be shortened to <9, 0>

In general, the notation $(x,y) \to (x+a, y+b)$ is shortened to the translation vector notation $< a, b >$ . In this case, a = 9 and b = 0.

The solution to the algebraic equation, −0.4x − 3.1 = 5.9, is:<u> x = -22.5</u>

Given the algebraic equation, −0.4x−3.1 = 5.9, to solve for x, follow the steps below:

−0.4x − 3.1 = 5.9

Add 3.1 to both sides

−0.4x − 3.1 + 3.1 = 5.9 + 3.1

-0.4x = 9

Divide both sides by -0.4

-0.4x/-0.4 = 9/-0.4

x = -22.5

Therefore, the solution to the algebraic equation, −0.4x − 3.1 = 5.9, is:<u> x = -22.5</u>

Find the value of x. Round your answer to the nearest tenth.

skad [1K]

Answer:

x = 9.7

Step-by-step explanation:

Reference angle (θ) = 68°

Opposite = 24

Adjacent = x

Apply, the trigonometric function, TOA which is:

$tan (/theta) = \frac{Opp}{Adj}$

Plug in the values

$tan 68 = \frac{24}{x}$

Multiply both sides by x

$x*tan 68 = 24$

Divide both sides by tan 68

$x = \frac{24}{tan 68}$

x = 9.69662942

x = 9.7 (nearest tenth)

<u>To find the density:</u>

⇒ must find the relationship between the density, mass, and volume

⇒ $Density = \frac{mass}{volume}$

<u>Let's examine the information given:</u>

weight: 1890g
dimensions: 8cm * 5cm* 5cm

<u>Let's first find the volume:</u>

⇒ the volume is the dimensions multiplied together

$Volume = 8cm * 5cm * 5cm = 200cm^3$

<u>LEt's calculate the density now:</u>

$Density = \frac{1890g}{200cm^3} =9.45g/cm^3$

<u>Answer:</u> The density of the copper is <u>9.45g/cm^3</u> or <u>Choice (A)</u>

I need help with this<br>

Mashutka [201]

Answer: D

Step-by-step explanation:

<u><em>When a coordinate is reflected over the y-axis, it changes from (x, y) to (-x, y)</em></u>

<em>The three coordinates of ΔCDE are</em>

C = (-8, -1)
D = (-6, -5)
E = (-2, -4)

<em>After the y-axis reflection, they'll become:</em>

C' = (-(-8), -1) = (8, -1)
D' = (-(-6), -5) = (6, -5)
E' = (-(-2), -4) = (2, -4)

<em>I hope this is correct :\</em>
