The equation of line passes through the point (4, 2) will be;

⇒ y = 12x - 46

What is Equation of line?

The equation of line in point-slope form passing through the points (x₁ , y₁) and (x₂, y₂) with slope m is defined as;

⇒ y - y₁ = m (x - x₁)

Where, m = (y₂ - y₁) / (x₂ - x₁)

Given that;

The point on the line are (4, 2).

And, The slope = 12

Now,

Since, The equation of line passes through the point ( 4, 2).

And, The slope = 12

Thus, The equation of line with slope 12 is,

⇒ y - 2 = 12 (x - 4)

⇒ y - 2 = 12 (x - 4)

⇒ y - 2 = 12x - 48

⇒ y = 12x - 48 + 2

⇒ y = 12x - 46

Therefore, The equation of line passes through the point (4, 2) will be;

⇒ y = 12x - 46

HELP ME it's almost due<br> find the length of the diagonals of rectangle QRST
Westkost [7]

Answer:

11.since diagonal are equal of rectangle

QS=RT

4x+6=6x-4

6+4=6x-4x

2x=10

x=10/2

x=5

now

diagonal :4x+6=4*5+6=<u>26</u>

12.

again

QS=RT

9x+12=11x-10

12+10=11x-9x

2x=22

x=11

now

diagonal=9*11+12=99+12=<u>111</u>

Find the standard deviation of the distribution in the following situations. (Round your answers to two decimal places.) (a) MEN
Arturiano [62]

Answer:

a) 15.579

b) 39.019

Step-by-step explanation:

a) For the top 2% the z-value from the z table

z = 2.054

thus,

z = \frac{\textup{X-Mean}}{\sigma}

here

X = 132

Mean = 100

thus,

2.054 = \frac{\textup{132-100}}{\sigma}

or

σ = 15.579

b) Using tables, we get for Z = 0.89 the value of 0.8133 and for Z= 0.90 the value of 0.8159

By interpolation, values for 0.815 and we get Z=0.897

thus,

z = \frac{\textup{X-Mean}}{\sigma}

here

X = 220

Mean = 185

thus,

0.897 = \frac{\textup{220-185}}{\sigma}

or

σ = 39.019

Find the Equation of the line
romanna [79]

Answer:

y = \frac{1}{2}x + \frac{1}{2}

Step-by-step explanation:

Mark any two point on the line

(-1 , 0)  & (-3 , -1)

Slope = \frac{y_{2}-y_{1}}{x_{2}-x_{1}}\\

          = \frac{-1-0}{-3-[-1]}\\\\= \frac{-1}{-3+1}\\\\= \frac{-1}{-2}\\\\= \frac{1}{2}

m = 1/2   ; (-1 , 0)

Equation: y - y_{1} =m(x -x_{1})

y - 0 = \frac{1}{2}(x - [-1])\\\\y = \frac{1}{2}(x + 1)\\\\y = \frac{1}{2}x + \frac{1}{2}
