(x-3)²+y²=9
(x-3)²+(y-0)²=3²
The equation can be written in the form (x-p)²+(y-q)²=r², so it represents a circle with the radius r=3 and the center (3, 0)

Hope my answer helped u :)

Answer:

  • Center = (3, 0)
  • Radius = 3
  • Graph = see below

Concept:

Here, we need to know the idea of the circle equation.

Circle equation: (x - h)² + (y - k)² = r²

(h, k) = center

r = radius

x = variable

y = variable

Solve:

<u>Given expression </u>

(x - 3)² + y² = 9

<u>Find the point of the center</u>

(h, k) = \boxed{(3,0)}

<u>Find the length of the radius</u>

r² = 9

\boxed{r=3}

Hope this helps!! :)

Part 1: Create your own quadratic equation that cannot be solved by factoring, but can be solved using the quadratic formula. Id
eimsori [14]
when you use all prime, non-one numbers for b and c, it cannot be factored most of the time


example
1x^2+7x+5
a=1
b=7
c=5
x=\frac{-b+/- \sqrt{b^2-4ac} }{2a}
x=\frac{-7+/- \sqrt{7^2-4(1)(5)} }{2(1)}
x=\frac{-7+/- \sqrt{49-20} }{2}
x=\frac{-7+/- \sqrt{29} }{2}
x=\frac{-7+ \sqrt{29} }{2} or \frac{-7- \sqrt{29} }{2}

Solve the system of equations.<br><br> 14x + y = −4<br><br> y = 3x^2 − 11x − 4
sveta [45]
You can use substitution here. First, get y alone:

14x + y = -4
subtract 14x from each side
y = -4 - 14x

Then, plug y into the second equation

-4 - 14x = 3x² - 11x - 4
 then solve from there

Hope this helps :)

PLEASE HELP ASAP!!! (No links)

Answer:

No it is not a solution

Step-by-step explanation:

To solve this, you should replace your (x,y) with (8,3)- 8 being your x value and 3 being your y value.

So this inequality, your y value is supposed to be bigger than the value of whatever 3x-4 equals.

So, your inequality should be 3>3(8)-4

3*8=24-4=20

So is 3>(greater than)20? No. Which then means that (8,3) is not a solution because it would make the inequality not true.

Hope this helps!
