Given x(y + 2) = 3x + y, express y in terms of x.​

Answers

Answer 1
Answer:

Answer:

y = (x)/(x-1)

Step-by-step explanation:

Given

x(y + 2) = 3x + y ← distribute parenthesis on left side

xy + 2x = 3x + y ( subtract 2x from both sides )

xy = x + y ( subtract y from both sides )

xy - y = x ← factor out y from each term on the left side )

y(x - 1) = x ← divide both sides by (x - 1)

y = (x)/(x-1)

Determine whether the polynomial is a difference of squares and if it is, factor it. y^2 – 225



is a difference of squares: (y + 15)^2

is a difference of squares: (y – 15)(y + 15)

is not a difference of squares

is a difference of squares: (y – 15)^2

Answers

(y-15)(y+15) if you do (y+15)^2, then that'll be y^2 + 225

There are approximately 7.5x10^18 grains of sand on earth.There are approximately 7x10 ^27 atoms in an average human body.Are there more grains of sand on earth or atoms in an average human body ?How do you know?

Answers

Answer:

Step-by-step explanation:

There are approximately 7.5 × 10¹⁸ grains of sand on earth.

There are approximately 7 × 10²⁷ atoms in an average human body.

A. There are more atoms in an average human body. When comparing the order of magnitude of each number 27 it greater than 18.

7 × 10²⁷ > 7.5 × 10¹⁸

B.  Now we will calculate how many times more atoms are in a human body compared to grains of sand on earth.

(7* 10^(27))/(7.5* 10^(18))

= (7)/(7.5)* (10^(27))/(10^(18))

≈ 1 × 10²⁷⁻¹⁸

≈ 1 × 10⁹

≈ 10⁹

There are approximately 1,000,000,000 atoms more in a human body compared to the grains of sand on earth.
There are more atoms in a human body because 7.5*10^18 is less than 7*10^27.

Please help. A skyrocket is launched from a 6 foot high platform with initial speed 200ft/s. The polynomial -16t^2 + 200t + 6 gives the height in feet the skyrocket will rise in t seconds. How high will the rocket rise in 6 seconds

Answers

The height of the rocket after 6 seconds is 630 feet

Functions and values

Given the polynomial function that represents the height of the rocket expressed as:

f(t) = -16t^2 + 200t + 6

If the time the rocket take to rise is 6 seconds, hence;

f(6) = -16(6)^2 + 200(6) + 6

f(6) = - 576 + 1200 + 6

f(6) = 630 feet

Hence the height of the rocket after 6 seconds is 630 feet
