First, we have to notice that 0 = (2*0)^2
and 4 = (2*1)^2
and 16 = (2*3)^2
and 64 = (2*4)^2
The y value is always the square of twice the x value or,
y = (2x)^2   or   y = 4x^2

Dora bought a bottle of nail polish that was marked down by 20 percent from its original price of $4.50. Including a 9 percent s
igomit [66]

Answer:

3.92$

Step-by-step explanation:

The first step is to deduct 20% of 4.50 from 4.50.

20% of 4.50 is 0.2 x 4.50 = .90

4.50 - 0.90 = 3.60

That's the new price without the sales tax.

Now we need to add 9% of 3.60 to 3.60 to get the final cost.

9% of 3.60 is .09 x 3.60 = 0.32

3.60 + .32 = $3.92

Hope it helps.. If yes mark me BRAINLIEST

Tysm!

If e || f and a || b, what is the value of y. *
Blizzard [7]

Answer:

y = 90

Step-by-step explanation:

Since, e || f and a || b

Therefore, quadrilateral so formed is a rectangle.

Each angle of a rectangle is right angle.

\therefore \: y \degree = 90 \degree \\  \\  \huge \red{ \boxed{ \therefore \: y  = 90}}  \\  \\

What are the coordinates of the endpoints of the midsegment for △JKL that is parallel to KL⎯⎯⎯⎯⎯? Enter your answers in the boxe
algol [13]
The points you are looking for are the midpoints of segments JL and JK.
J(-2, -1), K(4, -5), L(0, -5)

The midpoint of segment JL is

(-2 + 0)/2, (-1 + (-5))/2) = (-2/2, -6/2) = (-1, -3)

The midpoint of segment JK is

(-2 + 4)/2, (-1 + (-5))/2) = (2/2, -6/2) = (1, -3)

Answer: The coordinates are (-1, -3), (1, -3)

Explain how to tell weather an event is as likely as not
Degger [83]
I think the answer may be that an event is as likely as not to happen when the probability of the event happening is 50%, and the probability of the event not happening is 50%. Like a coin toss, the chance you will flip a "heads" is 1/2 or 50%, and the chance that you WON'T flip a heads is also 1/2 or 50%

What is the equation, in slope-intercept form, of the line that is perpendicular to the line
wolverine [178]

Answer:

y=3/2x+1

Step-by-step explanation:

y-4= -⅔(x-6)

y-4=-⅔x+4

y=-⅔x+4+4

(equation of line 1) y= -⅔x+8 gradient= -⅔

(line 2)gradient=3/2

note* the gradients of perpendicular lines multiplied result to -1

gradient=<u>y²-y²</u>

<u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u>x²-x¹

<u>3</u><u> </u>=<u>y</u><u>+</u><u>2</u>

<u> </u><u> </u>2. x+2

multiply both sides by 2(x+2)to remove the denominators

3(x+2)=2(y+2)

3x+6=2y+4

3x+6-4=2y

3x+2=2y

divide all sides by 2

3/2x+1=y

y=3/2x+1
