520 x 0.2 = 104
520 + 104 = 625
Curtley's annual heating cost before he got his loft insulated was $624.00
Answer:
(- 3, 5 )
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 + 3)² + (y - 5)² = 1 ← in standard form
with centre = (h, k) = (- 3, 5 )
Answer: 130
Step-by-step explanation:
Plug in 3 for x
It’s hard to completely answer without a graph or coordinates, but I do believe that point slope form is y-y1=m(x-x1). Plug in your slope for m. After that, plug in your x coordinate in the appropriate place as well as your y coordinate. Solve from there
