Use the distributive property to simply 27-9x+15y

Mathematics

Distributive property: ⇒ a(b+c)=ab+ac

First you had to rewrite down as the nine and its should be three times three is equal to nine. Then you rewrite down as the twenty-seven and its should be nine times three is equal to twenty-seven. Next, you rewrite down as fifteen and its should be five times three is equal to fifteen.

And it gave us ⇒ =5*3y+9*3-3*3x.

Then you had to factor out by the common term of three.

And it gave us ⇒ 3(5y+9-3x)

Final answer ⇒ \boxed{=3(5y+9-3x)}

Hope this helps!

And thank you for posting your question at here on brainly, and have a great day.

All 3 terms have a common factor 3 which we can take out

=3 ( 9 - 3x + 5y )

Find the center of the circle: x2 + 2x - 3 + y2 = 5.
rosijanka [135]

Answer:

\boxed{(-1, 0)}

Step-by-step explanation:

x² + 2x - 3 + y²  = 5

Strategy:

Convert the equation to the centre-radius form:

(x - h)² + (y - k)² = r²

The centre of the circle is at (h, k) and the radius is r .

Solution:

Move the number to the right-hand side.

x² + 2x + y²  = 8

Complete the square for x

(Take half the coefficient of x, square it, and add to each side of the equation)

(x² + 2x + 1) + y² = 9

Complete the square for y

The coefficient of y is zero.

(x² + 2x + 1) + y² = 9

Express the result as the sum of squares

(x + 1)² + y² = 3²

h = -1; k = 0; r = 3

The centre of the circle is at \boxed{(-1,0)}

The graph of the circle below has its centre at (-1,0) and radius 3.

What is the equation for the vertical asymptote of the function shown below? f(x)=3x^4-3/2x-5
levacccp [35]
f(x)= \frac{3x^4}{2x-5}

the va's are where x is undefined, or where the denomenator is zero
first simplify if applicable
cannot simplify

set denom to zero
2x-5=0
2x=5
x=2.5

the vertical assemtote is vertical so it is x=2.5 or 5/2

the VA is x=5/2
