Answer:

Step-by-step explanation:
Two Tangent Theorem: Tangents which meet at same point are equal in length.
Here tangents at J and H meet at I.

10 x 40 = 400 so the answer is 400 pieces of chalk.
Answer:
-2/3
Step-by-step explanation:
Answer:
exponential. not linear functions because they change by equal differences not intervals.
Answer:
Step-by-step explanation:
1 + 3 = 4
so find the point 1/4 of the way from (-1, 2) to (7, 8)
x coordinate
Δx = ¼(7 - (-1)) = 2
x = x₀ + Δx
x = -1 + 2 = 1
y coordinate
Δy = ¼(8 - 2) = 1½
y = y₀ + Δy
y = 2 + 1½ = 3½
(1, 3½)
