Answer:
see explanation
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
(x + 4)² + (y + 6)² = 16 is in this form
with r² = 16 ⇒ r = = 4
---------------------------------------------------------------
given (h, k) = (5, 2) and r = 20, then
(x - 5)² + (y - 2)² = 400 ← represents the delivery area
Answer:
<em>y = - x + 5 </em>
Step-by-step explanation:
A(1, 4)
B(4, 1)
= = - 1
y - 1 = - 1 ( x - 4 )
<em>y = - x + 5</em>
P=12/3
Explanation: P is the variable and to find how many we can buy with 12 dollars we divide 12 by 3 which is the price.
Answer:
y = - 5/2x - 23/2
Step-by-step explanation:
b = y - (slope)(x)
b = -4 - (-5/2)(-3)
b = -4 - 15/2 = - 23/2
y = -5/2x - 23/2
