x.x=30
2x=30
x=30/2=15
x+x=17
15+x=17
x=17-15
x=2
Reemplazamos:
15+2=17
<em>x</em> ² - 4<em>x</em> + <em>y</em> ² + 8<em>y</em> = -4
(<em>x</em> ² - 4<em>x</em> + 4) + (<em>y</em> ² + 8<em>y</em> + 16) = -4 + 4 + 16
(<em>x</em> - 2)² + (<em>y</em> + 4)² = 16
(<em>x</em> - 2)² + (<em>y</em> + 4)² = 4²
which is the equation of a circle centered at (2, -4) and with radius 4.
Answer:
Step-by-step explanation:
The common ratio is the constant found by dividing any term by the previous term.
r=6/36=1/6
r=1/6
I am assuming the 16 at the end of the sequence was a typo. IF 16 was at the end of the sequence it is NOT a geometric sequence as there would not be a common ratio for all terms.
Answer:
x=-11/8
Step-by-step explanation:
First use the Distributive property on [3(2x-1)]:
5x+6x-3=3x-14
Now combine alike terms:
11x-3=3x-14
Now add three to both sides:
11x=3x-11
Now subtract 3x from both sides:
8x=-11
Now divide both sides by 8:
x=-11/8
This fraction cannot be simplified meaning your final answer SHOULD be -11/8
