X = amount of lawns
y = amount of dog walks
25x + 15y = 1975
25x + 15(50) = 1975
25x + 750 = 1975
25x = 1225
x = 49
so x ≤ 49 (this number depends on how much Sarah walks)
y ≥ 50 (is how much Sarah walks)
hope this helps

The equation of a
circle is:
(x - h)² + (y - k)² = r²
The equation of a
parabola is:
(x - h)² = 4p(y - k)
The equation of an
ellipse is:

where variables a and b and the two different measurements of the vertices
The equation of a
hyperbola is:

if it is with a horizontal transverse axis

if it is with a vertical transverse axis
Notice these have a subtraction operation, the exact opposite ellipse.
