How does y=mx+c work

1 answer:

8 0

Ok so, y = mx + c is the equation of a line
When a graph is written in this form, m is the slope/gradient and c is the y - intercept.
This form is needed when a question asks for the equation.
Lets say they give 2 sets of coordinates, we can use the point slope formula to find the slope (m)

point slope formula:
(y₂ - y₁) = m(x₂ - x₁)

Then we substitute any of the two set of coordinates to find c, the y - intercept.

So the line has a gradient of m and y - intercept of c

What percent of 75 is 24?

Scilla [17]

Answer:

<h2>Your Answer is 32%</h2>

Explaination:

We already have our first value 75 and the second value 24. Let's assume the unknown value is Y which answer we will find out.

We already have our first value 75 and the second value 24. Let's assume the unknown value is Y which answer we will find out.As we have all the required values we need, Now we can put them in a simple mathematical formula as below:

STEP 1 >> Y = 24

75

STEP 2 >>

24 × 100 = 32

75 × 100 100

STEP 3>> Y = 32%

Finally, we have found the value of Y which is 32 and that is our answer.

You can use a calculator to find what percent of 75 is 24, just enter 24 ÷ 75 × 100 and you will get your answer which is 32.

Answer:

modulus: 3√2
argument: -3π/4 (or 5π/4)

Step-by-step explanation:

The modulus is the magnitude of the complex number; the argument is its angle (usually in radians).

<h3>rectangular form</h3>

The complex number can be cleared from the denominator by multiplying numerator and denominator by its conjugate:

$\dfrac{-9+3i}{1-2i}=\dfrac{(-9+3i)(1+2i)}{(1-2i)(1+2i)}=\dfrac{-9+3i-18i-6}{1+4}=-3-3i$

<h3>polar form</h3>

The magnitude of this number is the root of the sum of the squares of the real and imaginary parts:

modulus = √((-3)² +(-3)²) = 3√2

The argument is the arctangent of the ratio of the imaginary part to the real part, taking quadrant into consideration.

arg = arctan(-3/-3) = -3π/4 or 5π/4 . . . . radians

modulus∠argument = (3√2)∠(-3π/4)
