Question 3(Multiple Choice Worth 2 points)

zysi [14]

The solution to the equation are 5 or -1 after applying the quadratic formula.

<h3>What is a quadratic equation?</h3>

Any equation of the form $\rm ax^2+bx+c=0$ where x is variable and a, b, and c are any real numbers where a ≠ 0 is called a quadratic equation.

It is given that:

x² - 4x² - 5 = 0

The above equation is a quadratic equation:

Using the quadratic formula:

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

Plug the values in the formula:

$\rm $x=\dfrac{-(-4)\pm\sqrt{(-4)^2-4(1)(-5)}}{2(1)}$$

After solving:

x = 5 or -1

Thus, the solution to the equation is 5 or -1 after applying the quadratic formula.

Answer:

A (NO) B(YES) C(YES)

Step-by-step explanation:

Law of sines is used to find the measurements of angles not sides. Law of cosines is used for the sides. And pythagorean theorum should be obvious as it is based on the sides of a right triangle.

What is the equation of the line that passes through the point (2, 1) and has a slope of 3/2?

Ilia_Sergeevich [38]

Given :-

A line having a slope of 3/2 passes through (2,1) .

To Find :-

The equation of the line .

Answer :-

According to the question ,

m = 3/2
Point = (2,1)

We know Point slope form of the line as ,

y - y¡ = m ( x - x ¡ )

Substitute ,

y - 1 = 3/2 ( x - 2 )
y - 1 = 3/2x - 3/2*2
y - 1 = 3/2x - 3
2( y -1) = 3/2x *2 - 3*2
2y - 2 = 3x - 6
3x - 2y -4 = 0

Hence the equation of the line is 3x -2y-4=0 .
