Answer:
Step-by-step explanation:
1 is y = 15x, in 9 years he will have saved $13,500
2 is x2 − 4x − 211 is y = 15x, in 9 years he will have saved $13,500
2 is x2 − 4x − 21
Answer:
RM ≈ 6.08 ( to 2 dec. places )
Step-by-step explanation:
to calculate the distance use the distance formula
• d = √(x₂ - x₁ )² + (y₂ - y₁ )²
with (x₁, y₁ ) = R(- 2, 3) and (x₂, y₂ ) = M(4, 2)
d = = = ≈ 6.08
the apir is nshfjdbdbdbd 7 and 8
1, -4, -9, -14, this is arithmetic sequencewith difference =d = -5 a12 = a1 +(n-1) d =1 +(12-1)(-5) = 1+(11)(-5) = 1 -55 = -54 sum of the first 12 terms =( n/2 ) * (a1 +a12) =12/2 (1-54) =6(-53) =-318
