Inverse of f(x)=2x^2+5

an assistant recieved a 3% raise bringing the salary to 43,989 what was the salary defore the raise? (round to the nearest dolla

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.

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>

i hope this helps! have a lovely day <3
