Answer:
= 4n + 11
Step-by-step explanation:
There is a common difference between consecutive terms, that is
19 - 15 = 23 - 19 = 4
This indicates the sequence is arithmetic with explicit rule
= a₁ + (n - 1)d
where a₁ is the first term and d the common difference
Here a₁ = 15 and d = 4 , then
= 15 + 4(n - 1) = 15 + 4n - 4 = 4n + 11
Answer:
Step-by-step explanation:
Y = kx is the direct variation equation. First find k, the could variation. 16 = k * 20. Divide both sides by 20. 16/20 = k 4/5 = k. The direct variation is "y=kx" . As "x" increases the value of "y" increases.
Divide because it's one length of the total area
Mindy ate 3/9 pieces or 1/3. Troy ate 1/4c, or 1/4 of the total cake, which I'm using as the variable c. So it would be 1/3+1/4c
