What is the equation of the line that has a slope of 2 and passes through the point (2,9)?
jenyasd209 [6]

Answer:

D

Step-by-step explanation:

use the formula for point slope form, since all of your choices are in that form : y-y1=m(x-x1) (m is the slope)

we're given that m=2 and the point is (2,9)

Substitute into the equation

y-9=2(x-2)

That means that the answer is D

Hope this helps!

Find the center and the radius of the circle with the equation:x^2+6x+y^2+4y+12=0
oksian1 [2.3K]

Answer:

The center is at (-3, -2) and the radius = 1.

Step-by-step explanation:

We can do this by converting the given equation to standard form.

x^2+6x+y^2+4y+12=0

x^2+6x+y^2+4y = -12

Completing the square on the x and y terms:

(x + 3)^2 - 9 + (y + 2)^2 - 4 = -12

(x + 3)^2 + ( y + 2)^2 = -12 + 9 + 4

(x + 3)^2 + ( y + 2)^2 = 1

So the center is (-3, -2) and the radius = 1.

The price of a notebook is 20% less than the price of a book. By what percent is the price of the book higher than the price of
TiliK225 [7]

The price of the book is 125% higher than the price of the notebook if the price of a notebook is 20% less than the price of a book.

<h3>What is the percentage?</h3>

It is defined as the ratio of two numbers expressed in the fraction of 100 parts. It is the measure to compare two data, the % sign is used to express the percentage.

Let x is the price of the book

And y is the price of the notebook,

Then,

y = x- 0.20x = 0.80x

x = (1/0.80)y

x = 1.25y

So x is 1.25 or 125% higher than the, y

Thus, the price of the book is 125% higher than the price of the notebook if the price of a notebook is 20% less than the price of a book.
