Solve for y
x = x (2x - 4) + y

The first x is squared I just can’t put a square in brainly

Answers

Answer 1

Answer:

y = −x^2 + 4x

Step-by-step explanation:

x^2 = x (2x - 4) + y

Let's simplify it and we get

x^2 = 2x^2 - 4x + y

Now, we want to get the y by itself

x^2 = 2x^2 - 4x + y

-x^2 = -4x + y

-x^2 + 4x = y

So, our answer is y = −x^2 + 4x

Answers

Answer:

how to solve 2x+2y=2 , -4x+4y=12

this is solving equations using substitution .... i have ALOT more but i juss dnt get this stuff

2x + 2y = 2 -4x + 4y = 12

x + y = 1

x = 1 - y

-4x + 4y = 12

-4(1 - y) + 4y = 12

(-4 + 4y) + 4y = 12

-4 + 8y = 12

8y = 16

y = 2

2x + 2y = 2

2x + 2(2) = 2

2x + 4 = 2

2x = -2

x = -1

Check.

-4x + 4y = 12

-4(-1) + 4(2) = 12

4 + 8 = 12

Toms banks baleances at the end of the months 1,2,3 are 1600 ,1664,1730.56 what will toms balance be at the end of month 5

Answers

Answer:

Tom's balance at the end of month 5 = 1,871.77

Step-by-step explanation:

a = 1600

ar = 1664

ar² = 1730.56

common ratio, r = ar/a

= 1664/1600

= 1.04

r = 1.04

what will toms balance be at the end of month 5

Month 5 = ar⁴

= 1600 * 1.04⁴

= 1600 * 1.16985856

= 1,871.773696

Approximately 1,871.77

Tom's balance at the end of month 5 = 1,871.77

how to change
a fraction into a percent

Answers

Answer:

[see below]

Step-by-step explanation:

If you are given a fraction, convert it into a decimal by diving the numerator by the denominator.

After converting it into a decimal, you multiply it by 100 to get the percent value. After that, you add the percent sign.

Example:

[tex]\text{Convert \frac{5}{10} into a percent.}[/tex][tex]\text{Convert } \frac{5}{10} \text{ into a percent.}\\\\\\\rightarrow \text{Step One: Convert into decimal.}\\\\\frac{5}{10}=0.5\\\\\rightarrow \text{Step Two: Multiply by 100 and then add percent sign.}\\\\0.5 * 100 = 50\\\\[/tex]

50%

[tex]\frac{5}{10}=50[/tex]%

Hope this helps.

Answer:

Divide the numerator into the denominator, then move the decimal 2 places to the right.

Step-by-step explanation:

Let's use 3/4 as an example.

Divide 3 into 4 and you get 0.75

Move the decimal 2 places to the right and you get 75

Then just add a percent sign (75%)

I hope this helps, and have a great day! :)

Electrostatic precipitators use electric forces to remove pollutant particles from smoke, in particular in the smokestacks of coal-burning power plants. One form of precipitator consists of a vertical, hollow, metal cylinder with a thin wire, insulated from the cylinder, running along its axis (Figure 1). A large potential difference is established between the wire and the outer cylinder, with the wire at lower potential. This sets up a strong radial electric field directed inward. The field produces a region of ionized air near the wire. Smoke enters the precipitator at the bottom, ash and dust in it pick up electrons, and the charged pollutants are accelerated toward the outer cylinder wall by the electric field. Suppose the radius of the central wire is 80.0 um, the radius of the cylinder is 14.0 cm, and a potential difference of 50.0 kV is established between the wire and the cylinder. Also assume that the wire and cylinder are both very long in comparison to the cylinder radius.What is the magnitude of the electric field midway between the wire and the cylinder wall?
