Hey there!

It makes a sense. It is the equation of a straight line in slope intercept form.

We use this formula when need to find the equation of a st.line passing through point or to find the slope from the equation.

In this equation "m" represents slope of a line, "x" is a variable, "b" is the constant value, and "y" is a also a variable.

Example:

Find slope from the equation y= 3x+5.

》Solution,

Given;

y = 3x+5.....(i)

Comparing the equation with y =mx+b, we get;

slope (m)= 3.

Hope it helps..

Factor completely 36x2− 121.

lesantik [10]

The expression 36x² - 121 is in the 'difference of two squares form' which is (a² - b²)

Factorising (a² - b²) gives (a+b)(a-b)

Factorising 36x² - 121 gives (6x+11)(6x-11)

Karina is designing a logo on a coordinate plane. The logo is a square whose area is 200 square units. She places a circle in th

Katarina [22]

Answer:

Step-by-step explanation:

To find the percentage we must first find the area of the circle:

We can find the radius of the circle using the distance formula;

⇒ $d = \sqrt{(x_{2} - x_{1})^{2} + (y_{2} - y_{1})^{2}}$

⇒ $r = \sqrt{(6.3 - 0)^{2} + (1.6 - 0)^{2}}$

⇒ $r = 6.5$

Now we calculate the area;

⇒ $A = \pi r^{2}$

⇒ $A = \pi (6.5)^{2}$

⇒ $A = \frac{169}{4}\pi$

To get the percentage we divide the area of the circle by the square’s are and multiply by 100;

⇒ $Percentage = \frac{42.25\pi }{200} * 100$

⇒ $Percentage = 66 (2sf)$
