Y=2.50x+20. Plug in values for x starting at 0 and you will get values for y and then graph.
(x - h)^2 + (y - k)^2 = r^2
h = -2
k = -2
r = 6
(x - (-2))^2 + (y - (-2))^2 = 6^2
(x + 2)^2 + (y + 2)^2 = 6^2
(x + 2)^2 + (y + 2)^2 = 36. your answer

Answer:
(- 1, - 1 )
Step-by-step explanation:
Since the dilatation is centred at the origin, then multiply the coordinates of the original point by the scale factor, that is
(- 3, - 3 ) → (
× - 3,
× - 3 ) → (- 1, - 1 )
First, convert your mixed numbers into improper fractions, so 8+3/8=69/8 and 2+1/3=7/3. Now you have 69/8=r-(7/3). Now, add 7/3 to both sides, so (69/8)+(7/3)=r. Now, just add your fractions, so (69/8)+(7/3)=207/24+56/24=(207+56)/24=263/24. If you need to, this can be converted back into the mixed number 10+23/24.
