lesya692 [45]
If her original salary is x, then her new salary is 103% of x.
To obtain x from 43989, you therefore divide 43989 by 1.03 to get:
42708 (to nearest dollar).
You can the check it by multiplying by 1.03.

2n^3-3n^2+2n=o<br>answer needed urgently pls​
Kazeer [188]

n = 0

Step-by-step explanation:

<h2><em>Factor the </em><em>expression</em></h2>

<em>2n ^ 3 - 3n ^ 2 + 2n = 0</em>

<h2><em>Separate into possible cases</em></h2>

<em>n(2n ^ 2 - 3n + 2) = 0</em>

<h2><em>Solve the equation</em></h2>

<em>n = 0[tex]n = 0 \:  \:  \:  \:  \:  \:  \:  \: [tex]n = 0 \:  \:  \:  \:  \:  \:  \:  \: 2n ^ 2 - 3n + 2 = 0</em>

<h2><em>Find the union</em></h2>

<em>n = 0[tex]n = 0 \:  \:  \:  \:  \:  \: [tex]n = 0 \:  \:  \:  \:  \:  \: n =  R</em>

Choose the algebraic description that maps the image ΔABC onto ΔA′B′C′.
murzikaleks [220]

The algebraic description that maps the image ΔABC onto ΔA′B′C′ is (x, y) ⇒ (x + 7, y - 4)

<h3>What is transformation?</h3>

Transformation is the movement of a point from its initial location to a new location. Types of transformations are<em> reflection, rotation, translation and dilation.</em>

Translation is the movement of a point either <em>up, left, right or down</em> in the coordinate plane.

The algebraic description that maps the image ΔABC onto ΔA′B′C′ is (x, y) ⇒ (x + 7, y - 4)

Question 8 of 10
Sliva [168]

Answer:

y = (-3/7)x + 2

Step-by-step explanation:

slope-intercept form is y = mx + b, where m = slope and b = y-intercept.

all you need to do is plug the values into the equation! :)

since your slope is (-3/7), plug that in for m.

y = mx + b ⇒ y = (-3/7)x + b

and since your y-intercept is 2, plug that in for b.

y = (-3/7)x + b ⇒ y = (-3/7)x + 2

therefore, the line's equation in slope-intercept form is y = (-3/7)x + 2.

<em>don't worry about the parentheses, i only put them in there to separate the 7 in -3/7 from x. i'm not good at putting equations in here on brainly lol i just wanted to make sure you didn't think that it was -3 over 7x.</em>

<em />

i hope this helps! have a lovely day <3
