Solve: Vx+1= Vx+6 -1

Mathematics
1 answer:
swat323 years ago
3 0

Answer:

x + 1 = x +7-2\sqrt{x+6}

Step-by-step explanation:

\sqrt{x+1}= \sqrt{x+6}-1

Squaring both sides of the equation would give (\sqrt{x+1} )^{2} =(\sqrt{x+6}-1 )^{2} which then simplifies to x + 1 = x -2\sqrt{x+6}+7

We can then subtract 7 from both sides to get x-6=x-2\sqrt{x+6}

Then we can subtract x from both sides, which cancel out and we get -6 =-2\sqrt{x+6}

Then we need to divide both sides by -2 to get 3=\sqrt{x+6}

Then we need to square both sides (3)^{2} =(\sqrt{x+6} )^{2} to get rid of the square root to get 9 = x + 6

Then finally subtracting 6 from both sides we get 3 = x

Write 600 as a product of it's primse factors
givi [52]

Answer:

2*2*2*3*5*5

or

2^3 *3* 5^2

Step-by-step explanation:

600  = 60*10

These are not prime so keep going, breaking 60 and 10 down

        = 6*10  * 5*2

6 and 10 are not prime so keep going ( 5 and 2 are prime)

    = 3*2  * 5*2  * 5*2

All of the numbers are prime, so we normally write them in order from smallest to largest

2*2*2*3*5*5

We can write with exponents

2^3 *3* 5^2

use the point–slope formula to write an equation of the line that passes through(-5, -16 )and has a slope of m = 3 . Write the a
scoray [572]

Answer:

y + 16 = 3(x + 5)

Step-by-step explanation:

When you write an equation in point-slope form, you only need two things: a point and a slope.

Given:

  • point: (-5, -16)
  • slope (m): 3

The standard point-slope equation is

y - y₁ = m(x - x₁)

Plug in what you know.

y - (-16) = 3(x - (-5))

Simplify.

y + 16 = 3(x + 5)

This is your equation.
