Answer:

x-4+(20)/(x+4)

Using the quadratic formula, the value of x in the given situation is x = 4 ± √2+60x/2x.

The quadratic formula in elementary algebra is a formula that yields the answer to a quadratic problem.

In addition to the quadratic formula, other methods of solving quadratic equations include factoring, completing the square, graphing, and others.

A second-order equation of the form ax² + bx + c = 0 denotes a quadratic equation, where a, b, and c are real number coefficients and a 0.

We have:
x² – 2x = 15

x² – 2x - 15 = 0

The formula is:

x = -b ± √b² - 4ac/2a

Now, insert values as follows:

x = -b ± √b² - 4ac/2a

x = -(-2) ± √(-2)² - 4(x)(-15)/2x

x = 4 ± √2+60x/2x

Therefore, using the quadratic formula, the value of x in the given situation is x = 4 ± √2+60x/2x.

Answer:

nope

Step-by-step explanation:

No,  s=2/3 is not a solution of 6s−1 = 3s.

Equations whose variables have a power of one are called linear equations. One example with one variable is where ax+b = 0, where a and b are real values and x is the variable.

Given:

A linear equation,

6s − 1 = 3s.

Substituting,

s = 2/3,

Equation is,

3 ≠ 2

Simplifying,

6s - 3s = 1

3s = 1

s = 1/3

That means, s = 1/3 is the only solution of the equation.

Therefore, s = 2/3 is not a solution to the equation.

Answer:

(0, 1) and (4, 7)

Step-by-step explanation:

We are going to find the equation that satisfy the question.

The equation of a line is: [tex]y=mx+b[/tex], where m is the slope and b is the y-intercept.

The problem gives us the slope and a point the line passes through.

In order to find b, we plug in the given point (2,4) and solve.

[tex]4=\frac{3}{2} *2+b[/tex]

[tex]4=3+b\\1=b\\[/tex]

The equation for the line is:

[tex]y=\frac{3}{2} x+1[/tex]

By plugging in the points to see if it is true, we get that only (0,1) and (4,7) are on the line.

Answer:

one solution

the solution is x=0

Answer:

1

Step-by-step explanation:

You can figure this out using a simple trick. The highest number to the power that a variable goes to is the number of answers for that question. Meaning if There was an x cubed in that problem, there would be 3 answers.

Use the squeeze theorem; if

1 - x ²/4 ≤ u(x) ≤ 1 + x ²/2,

then taking the limit on each part as x approaches 0 gives

1 ≤ lim [x → 0] u(x) ≤ 1

and so the limit of u(x) as x → 0 is simply 1.

Answer:

Eliminating the parameter, the equation is [tex]y = x - 2[/tex]

Step-by-step explanation:

We are given the following parametric equations:

[tex]x = t^2 + 1[/tex]

[tex]y = t^2 - 1[/tex]

We want to eliminate the parameter t. From the first equation:

[tex]x = t^2 + 1[/tex]

[tex]t^2 = x - 1[/tex]

Replacing in the second equation:

[tex]y = x - 1 - 1[/tex]

[tex]y = x - 2[/tex]

Eliminating the parameter, the equation is [tex]y = x - 2[/tex]
