The 5th term of linear sequence is 17
dedylja [7]

Answer:

397

Step-by-step explanation:

lets say there's an eqn which is y = mx + c, x is the term no. (5, 6 in the egs provided), y is the value corresponding to x (17, 21)

to find the 100th term sequence we need to find m and c. m is how much y changes when x increases by 1

in this case we can find m easily (m = 21-17 = 4)

now we have c left so just sub one of the egs given to what we have alrd found

17 = 4(5) + c

17 = 20 + c

c = - 3

so the eqn is y = 4x - 3, and we can solve for when x = 100

y = 4(100) - 3

y = 397

hope this isn't too confusing :^)

Help me -2 (8 - e) = 2 - e​
-BARSIC- [3]

Answer:

e = 6

Step-by-step explanation:

Step 1: Write equation

-2(8 - e) = 2 - e

Step 2: Solve for <em>e</em>

  1. Distribute -2: -16 + 2e = 2 - e
  2. Add e to both sides: -16 + 3e = 2
  3. Add 16 to both sides: 3e = 18
  4. Divide both sides by 3: e = 6

Step 3: Check

<em>Plug in e to verify it's a solution.</em>

-2(8 - 6) = 2 - 6

-2(2) = -4

-4 = -4
