Answer: x=-3
Step-by-step explanation:
2x-4(x+3)=x-3
2x-4x-12=x-3
-2x-12=x-3. add 12 to both sides
-2x=x+9. subtract x from both sides
-3x=9. Divide both sides by -3
x=-3
Common ratio, is r=6/3=12/6=2
Answer: common ratio 2
First term a₁ = 3
nth term aₙ = a₁rⁿ⁻¹ = 3 (2ⁿ⁻¹)
13th term = 3(2¹²) = 12288
Answer: 13th term is 12,288
Answer:
B
Step-by-step explanation:
RANGE are the Y values
Answer: let x be the number of songs downloaded
Each song is $1.29; the total cost would be found by multiplying the cost by the number of songs or $1.29x.
This cannot be more than 20 so we set this less than or equal to 20
1.29x < 20
To solve this we divide both sides by 1.29
<;
x < 15.5
We cannot download half a song so we round this down to 15 (although the number rounds up mathematically he would not have enough money to download 16 songs.) This means he can download at most 15 songs
