To determine the center points and the radius of the circle, we can either graph the equation or write it in a form where the center and the radius can be easily be seen. For this, we use the second method. The form should be:

(x - h)^2 + (y-k)^2 = r^2

(h,k) represent the center and r the radius

We do as follows:
<span>x2 + y2 -6x + 10y + 25 = 0
</span>x2 -6x + y2<span> + 10y = - 25
x2 - 6x + 9 + </span> y2 + 10y + 25 = -25 + 9 + 25 = 9
(x - 3)^2 + (y + 5)^2 = 3^2

Therefore, the center is at ( 3,-5) and the radius is 3 units.

-10n+50=-7(4n+8)-2 no solution many solution
ziro4ka [17]

Answer:

n=-6

Step-by-step explanation:

distribute -7 into (4n+8)

-10n+50=-28n-56-2

combine like terms

-10n+50=-28n-58

add -28n on both sides

-10n+28n+50=-58

combine like terms again

18n+50=-58

subtract 50 on both sides

18n=-108

divide both sides by 18

\frac{18x}{18} =\frac{-108}{18}

x=-6

hope this helps

notka56 [123]

Answer:

x = 5

Step-by-step explanation:

Given that, exterior angles on the same side of a traversal are supplementary a Hence, sums up to 180°

Given the angles:

7x° + 11x° + 90° = 180°

18x° + 90° = 180°

18x° = 180° - 90°

18x° = 90°

x = 90° ÷ 18

x = 5

Two consecutive even intergers whose sum is 110
Harrizon [31]
Consecutive even integers are 2 apart
they are
x and x+2


sum is 110
x+x+2=110
2x+2=110
minsu 2 both sides
2x=108
divide both sidedse by 2
x=54
x+2=56
the numbers are 54 and 56
