Answer:
Explicit formula is
Step-by-step explanation:
The given arithmetic sequence is 4/5, 29/30, 17/25, 13/10
The explicit formula of this sequence will be in the form of
Where = nth term of the sequence
= first term of the sequence
n = number of terms
and d = Second term - first term
Now we put the values in the explicit formula
Therefore the explicit formula of this arithmetic sequence is f(n)=
Answer:
x=-7 x=4
Step-by-step explanation:
(x −2)(x + 5) = 18
Foil
x^2 +5x-2x-10 = 18
Combine like terms
x^2 +3x -10 =18
Subtract 18 from each side
x^2 +3x -28 = 0
Factor
What two numbers multiply to -28 and add to 3: 7 and -4
(x+7) (x-4) =0
Using the zero product property
x+7=0 x-4 =0
x=-7 x=4
