K+5/3=-7/4 (those are fractions) also can you show your work?
iris [78.8K]

Answer:

-3 5/12=k

Step-by-step explanation:

K+5/3= -7/4

subtract 5/3 from both sides

K= -7/4-5/3

lcm of 4 and 3 is 12

so

K= -21/12-20/12

K= -41/12

K= -3 5/12

Which of the following answer choices is an equation for the circle with a center of (-2, 3) and a radius of 3?
mamaluj [8]

Answer:

A

Step-by-step explanation:

The equation of a circle in standard form is

(x - h)² + (y - k)² = r²

where (h, k) are the coordinates of the centre and r is the radius

Here (h, k) = (- 2, 3) and r = 3 , then

(x + 2)² + (y - 3)² = 9 ← expand left side using FOIL

x² + 4x + 4 + y² - 6y + 9 = 9  ( subtract 9 from both sides )

x² + y² + 4x - 6y + 4 = 0 → A
