Answer:
The next two terms and 5 and 8.
Step-by-step explanation:
Find the recursive formula (tₙ = tₙ₋₁ + d) of -4, -1, 2.
Arithmetic sequences have a common difference, "d" , between terms.
To find the common difference, subtract a term value from the term value after it.
-1 - -4 = 3
2 - -1 = 3
The common difference is 3.
To find the next term, add 3 to the previous term.
The recursive formula is tₙ = tₙ₋₁ + 3
tₙ = tₙ₋₁ + 3
t₄ = t₃ + 3
t₄ = 2 + 3
t₄ = 5
tₙ = tₙ₋₁ + 3
t₅ = t₄ + 3
t₅ = 5 + 3
t₅ = 8
Answer:
$212.50
Step-by-step explanation:
So you have to multiply 8.5 by 25 because for every hour she gets $25. And if she works for 8.5 hours then you multiply both numbers to get your answer.
Hope this helps!
Answer:
y=x+1/2z+-1/2
Step-by-step explanation:
Let's solve for y.
2x−2y+z=1
Step 1: Add -2x to both sides.
2x−2y+z+−2x=1+−2x
−2y+z=−2x+1
Step 2: Add -z to both sides.
−2y+z+−z=−2x+1+−z
−2y=−2x−z+1
Step 3: Divide both sides by -2.
-2y/-2 = -2-z+1/-2
y=x +1/2z+-1/2
