C=K x D
125= k x 5 so k= 125/5 = 25
answer is C= 25D
Answer:
17
Step-by-step explanation:The rule is that x is increased by one then added to x
So 5 + 6 = 1
So 8 +9= 17
Answer:
y = 2x-3
Step-by-step explanation:
y – 1 = 2(x – 2)
Distribute
y-1 =2x-4
Add 1 to each side
y-1+1 = 2x-4+1
y = 2x-3
Answer:
(x + 7)2 + (y + 1)2 = r2.
To get we use point (8, 7): (8 + 7)2 + (7 + 1)2 = r2, r2 = 225 + 64 = 289 = 172.
So, equation of circle: (x + 7)2 + (y + 1)2 = 289
