Answer:

The circle equation is x^{2}+y^{2}=9

Step-by-step explanation:

The rule of the equation of the circle whose center (h , k) and radius r is:

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

∵ The center of the circle is the origin (0 , 0) and its radius is 3

∴ The equation is (x-0)^{2}+(y-0)^{2}=3^{2}

∴ x^{2}+y^{2}=9

Nonamiya [84]

Answer:

x = 17

Step-by-step explanation:

5x + 29 + 2x + 32 = 180    (linear pair means that these angles add up to 180 cos they are in a line)

7x = 119

x = 17

What is the equation of the line that is perpendicular to the line y=3/5xplus 10 and passes through the point (15,-5)?
Allisa [31]

Step-by-step explanation:

a general line equation is

y = ax + b

the original line is

y = 3/5 x + 10

the factor of x is always the slope (inclination of the line).

it is "y change/x change".

the slope of a perpendicular line (angle of 90°) is turning the slope of the original line upside-down and flips the sign.

so, it is -5/3.

we use the point information to get the right "b" for our new line :

-5 = -5/3 × 15 + b

-5 = -5×5 + b

-5 = -25 + b

b = 20

so, the perpendicular line equation going through (15, -5) is

y = -5/3 x + 20
