What is the solution to the following equation? x2 + 3x + 4 = 0​
andreev551 [17]

Answer:

x=\dfrac{-3\pm \sqrt7i}{2}

Step-by-step explanation:

The given equation is x^{2}+3x+4=0.

We need to find the solution of the above equation.

The solution of an equation ax^2+bx+c=0 is :

x=\dfrac{-b\pm \sqrt{b^2-4ac} }{2a}

We have, a = 1, b = 3 and c = 4

x=\dfrac{-3+ \sqrt{(3)^2-4(1)(4)} }{2}, \dfrac{-3- \sqrt{(3)^2-4(1)(4)} }{2}\\\\=\dfrac{-3+\sqrt{9-16}}{2}, \dfrac{-3-\sqrt{9-16}}{2}\\\\=\dfrac{-3\pm \sqrt7i}{2}

So, the solution of the given equation is \dfrac{-3\pm \sqrt7i}{2}.

Which statement is true about the function f(x)= StartRoot negative x EndRoot?
UNO [17]

Answer:

The domain of the graph is all real numbers less than or equal to 0

Step-by-step explanation:

we have the function

f(x)=\sqrt{-x}

we know that

The radicand must be positive

so

-x \geq 0

Solve for x

Multiply by -1 both sides

x\leq 0

The domain is the interval ------> (-∞,0]

All real numbers less than or equal to zero

The range of the function is the interval -----> [0,∞)

f(x)\geq 0

see the attached figure to better understand the problem

All real numbers greater than or equal to zero

<em><u>Verify each statement</u></em>

case 1) The domain of the graph is all real numbers

The statement is false

Because, the domain is all real numbers less than or equal to zero

case 2) The range of the graph is all real numbers

The statement is false

Because, the range is all real numbers greater than or equal to zero

case 3) The domain of the graph is all real numbers less than or equal to 0

The statement is true

case 4) The range of the graph is all real numbers less than or equal to 0

The statement is false

Because, the range is all real numbers greater than or equal to zero

Find the value of x in the isosceles triangle.
vichka [17]

Answer:

Step-by-step explanation:

The total length of triangle is 40 in. The length of the right triangle is the total length divided by 2 which 40/2 = 20.

We have 2 right triangles. We can use the pythagorean theorem to solve for x.

a^2 + b^2 = c^2

x^2 + 20^2 = 25^2

x^2 + 400 = 625

      - 400  - 400

x^2 = 225

x = 15
