Answer:
a4 = 128
a5 = -512
Step-by-step explanation:
a1= -2
q= (-1)^(n+1) × 4
a4 = a1q³ = (-2) (-4)³ = -2 × -64 = +128
a5 = a1q⁴ = (-2) (-4)⁴ = -2 × 256 = -512
Answer:
The answer is $690.78
Step-by-step explanation:
Answer:
3 ( x-1) (x+1) is the factored form
zeros are x=1, -1
Step-by-step explanation:
3x^2-3
Factor out a 3
3 ( x^2 -1)
What is inside the parentheses is the difference of squares
( a^2 -b^2) = ( a-b)(a+b)
3 ( x-1) (x+1)
To find the zeros, set this equal to zero
3 ( x-1) (x+1) =0
Using the zero product property
x-1 =0 x+1 =0
x=1, x=-1
Answer:
A
Step-by-step explanation:
We know that there are two tickets (which we'll represent with x) and a fee for transporation (which is $20)
So we can set up the equation 20+2x=48
We want to isolate x so we'll subtract 20 from each side, which gives us the equation
2x=28
Then divide each side by 2
Giving us the final answer of
x=14
So each ticket costs $14
