Answer:
SSS similarity
Step-by-step explanation:
From the smaller triangle to the larger triangle, the ratio of each pair of corresponding sides is 2.
3y-9=6
add 9 to both sides
3y=15
Divdide both sides by 3
y=5 is the answer
Answer:
9.28 × 10⁻⁴ cm/year.
Step-by-step explanation:
Let d(t₀) represent the initial position of Kauai island = 0 km from the hot spot. at time t = 0 million years. Let d(t₁) represent its final position at time t₁ = 5.1 million years later in the North - west direction. d(t₁)=473 km = 4.73 × 10³ cm. The average speed v = total distance/ total time =[d(t₁) - d(t₀)]/t₁₋t₀ = (4.73 × 10³ - 0)/(5.1 × 10⁶ - 0) = 4.73/5.1 × 10³⁻⁶ = 9.275 × 10⁻⁴ cm/year ≅ 9.28 × 10⁻⁴ cm/year
In linear functions (mx+b), the m is the slope, therefore the -2 is the slope.
Answer:
-3mn + 14n - m is your answer.
Step-by-step explanation:
Combine like terms (terms with the same amount of variables). Reorder so that it is so:
(-5mn + 2mn) + (6n + 8n) + (-4m + 3m)
Combine like terms. Add or subtract the variables. Note that if there is no number, it is assumed that there is a 1:
(-5mn + 2mn) = (2mn - 5mn) = -3mn
(6n + 8n) = 14n
(-4m + 3m) = 3m - 4m = -m
(-3mn) + (14n) + (-m)
-3mn + 14n - m is your answer.
