c and a
by the way, thats easy. NO OFFENCE XD
We have two points so we can find the gradient using y1-y2/x1-x2
gradient = 21-27/2-8
= 1
we know the form for any linear equation is y = mx + c
we have m and a point so we can substitute in point (2,21) to find c
21 = 1 x 2 + c
c = 19
therefore, the equation is y = x + 19
Circumference = πD
30π = πD
D = 30 inches
Answer: 30 inches
Answer:
6
(x−7)(x−1) this is the correct answer
