The slope-intercept form of a linear equation is y=mx + b, where x and y are

Mathematics

Answer:

m = \frac{y-b}{x}

Step-by-step explanation:

Given

y = mx + b ( isolate the term in m by subtracting b from both sides )

y - b = mx ( divide both sides by x )

\frac{y-b}{x} = m

Answer:

y = 11x

Step-by-step explanation:

We have two points so we can find the slope

(1,11) and (2,22)

m = (y2-y1)/ (x2-x1)

   = (22-11)/(2-1)

   = 11/1

The slope is 11

We can use the point slope form to get an equation

y-y1 = m(x-x1)

y-11 = 11(x-1)

Distribute the 11

y-11=11x -11

Add 11 to each side

y-11+11 = 11x-11+11

y = 11x

In a right triangle, one of the legs is 5 cm smaller than the hypotenuse, and the other leg is 10 cm smaller than the hypotenuse
nata0808 [166]

Answer:

25 cm.

Step-by-step explanation:

If the hypotenuse is  x cm long the 2 legs are  x-5 and x-10 cm long.

So by the Pythagoras theorem:

x^2 = (x - 5)^2 + (x - 10)^2

x^2 = x^2 - 10x + 25 + x^2 - 20x + 100

x^2 - 30x + 125 = 0

(x - 5)(x - 25) = 0

x = 5, 25

We can discard x = 5 because that would make the lengths of the legs negative so the hypotenuse = 25 cm long.

A doctor develops the model y = 36.57x+4 for the number of words a toddler can speak (x) versus the months that have passed sinc
Rashid [163]
Either it probably is 4 which is the months or years that the toddler is and 36.57 would be the amount of words each month or year.
