Use the point-slope formula to write an equation of the line that passes through (6,23) and has a slope of m= 3. Write the answe

RSB [31]

y=3x+5

plug your coordinate points into the equation for slope (left corner or the paper)

multiply by the denominator on both sides of the equation

x-6 cancels out and leaves y-23=3(x-6)

multiply x and -6 by 3

add 23 to both sides to isolate y

hope this helps!

Simplify the given expression. –10xy(4xy3 – 7xy + 9y2)

Drupady [299]

Answer:

$\large\boxed{-40x^2y^4+70x^2y^2-90xy^3}$

Step-by-step explanation:

Use the distributive property <em>a(b + c) = ab + ac</em>:

$-10xy(4xy^3-7xy+9y^2)\\\\=(-10xy)(4xy^3)+(-10xy)(-7xy)+(-10xy)(9y^2)\\\\\text{use}\ a^na^m=a^{n+m}\\\\=-40x^{1+1}y^{1+3}+70x^{1+1}y^{1+1}-90xy^{1+2}\\\\=-40x^2y^4+70x^2y^2-90xy^3$

PLEASE HELP ANGLE OF TRIANGLE

nadya68 [22]

Answer:

my last answer was why the sum of two known angles is equal to the exterior angle so now you can use the easier way:

add the two known angles.

41+107 = 148

that means the exterior angle is equal to 148

x=148

Inscribe a circle in a unit square and to r= 1000 random.

Oduvanchick [21]

Step-by-step explanation:

area of square = 1

area of a circle in square = $\pi r^2 = \pi *(1/2)^2 = \frac{\pi }{4}$

bu estimate $p^ = X/n = 760/1000 = 0.76Therefore, 
[tex]\frac{\pi }{4} \approx 0.76$

$\pi \approx 0.76*4 =3.04$

b) if n tend to infinity

$\pi will approach 3.14$
