Answer:
Step-by-step explanation:
<u>Given recursive formula:</u>
- a₁ = -1
- aₙ = - 3aₙ₋₁ + 6 for n ≥ 2
<u>The first 4 terms are:</u>
- a₁ = - 1, given
- a₂ = - 3*(-1) + 6 = 3 + 6 = 9
- a₃ = - 3*(9) + 6 = - 27 + 6 = - 21
- a₄ = - 3*(-21) + 6 = 63 + 6 = 69
Plug in -6 for a and -5 for b
3(-6)^2 - 4(-5)
3(36)+20
108+20
=120
<7 and <10 are each 84 degrees
Well, 1x5=5 and 2x5=10 so 3x5=15
Answer:
d. m+ 3 = 15
Step-by-step explanation:
it explains you have to add m to 3 so it can't be m + 15. also, its says equals to 15 so 15 will be after the equal sign.
hope this helped... branliest please :)
