x=a-2by^2

Make “y” as a subject

Answers

Answer 1

Answer:

Let’s assume a,b,x real. Then all we require of y is y2 is real, so y

can be real or purely imaginary, but not an arbitrary complex number.

The hard question in these is always, do we need ±

? Here the answer is yes. It’s basically asking is there one solution or two, and in this problem we have two.

Solve for y

: x=a−2by2

the area of a square is 128x^3y^4 cm^2. what is the length of one side of the square in simplest form​

Answers

Answer:

one side = 8xy²·[tex]\sqrt{2x}[/tex]

Step-by-step explanation:

if the area is 128x^3y^4 then to find one side you must take the square root

[tex]\sqrt{128}[/tex][tex]\sqrt{x^3}[/tex][tex]\sqrt{y^4}[/tex] = [tex]\sqrt{4}[/tex][tex]\sqrt{32}[/tex][tex]\sqrt{x^2}[/tex][tex]\sqrt{x}[/tex][tex]\sqrt{y^2}[/tex][tex]\sqrt{y^2}[/tex] =

What is the image of (4,−8) after a dilation by a scale factor of 1/4 centered at the origin?

Answers

Answer:

(1,-2)

Step-by-step explanation:

you just have to multiply the coordinates by 1/4

4x1/4=1

-8x1/4=-2

so the new coordinates are (1,-2)

The image of the given point is (1,-2).

Important information:

The coordinates of the point are (4,-8).Point is dilated by a scale factor of [tex]\dfrac{1}{4}[/tex] centered at the origin.Dilation:

If a point is dilated by a scale factor of [tex]k[/tex] centered at the origin, then the rule of dilation is defined as:

[tex](x,y)\to (kx,ky)[/tex]

Using the above rule, we get

[tex](4,-8)\to \left(\dfrac{1}{4}(4),\dfrac{1}{4}(-8)\right)[/tex]

[tex](4,-8)\to \left(1,-2\right)[/tex]

Therefore, the image of the given point is (1,-2).

How to solve 6x + y= -5, -6x + 12y=96 using elimination and does it have no solution or many solutions?

Answers

Answer:

x = -2

Step-by-step explanation:

Arrange 6x + y= -5, -6x + 12y=96 vertically:

6x + y= -5

-6x + 12y=96       Now combine like terms:

--------------------

       13y = 91

Solving for y by dividing both sides by 13:  y = 7

Find x by substituting 7 for y in the second equation:  -6x + 12(7) = 96

Then -6x = -84 + 96, or:

-6x = 12, and so x = -2

What is a number line?

Integers are arranged at equal intervals along horizontal straight lines called number lines. A number line can be used to represent every number in a series. The endpoints of this line go on forever. Some will have a defined beginning and end. It refers to those as closed number lines. Number lines might be alternatively left empty or blank. A number ladder is a vertical number line.

Answer:

Step-by-step explanation:

I = $ 3,106.35

Equation:

I = Prt

Calculation:

First, converting R percent to r a decimal

r = R/100 = 3.9%/100 = 0.039 per year,

then, solving our equation

I = 17700 × 0.039 × 4.5 = 3106.35

I = $ 3,106.35

The simple interest accumulated

on a principal of $ 17,700.00

at a rate of 3.9% per year

for 4.5 years is $ 3,106.35.

$ 6,903.00 - 3,106.35 = 3796.65
