Step-by-step explanation:
Each term is double the previous term. The recursive formula is:
aₙ₊₁ = 2 aₙ
The first term is 9, so the explicit formula is:
aₙ = 9 (2)ⁿ⁻¹
If he had 100, and got 300 more:
100 + 300 = 400.
Bill now has 400 balloons.

Answer:
$240
Step-by-step explanation:
100 - 25 = 75 (Sheyna)
75% = 180
1% = 180 ÷ 75 = 2.4
100% = 2.4 x 100 = 240 (Muniyah)
Answer:
y = 10x - 3
Step-by-step explanation:
We have the point (0, -3), which is the y-intercept. In slope-intercept form,
y = mx + b,
that is the b.
Now we find the slope between the other 2 points:
So m = 10. Therefore, the equation is
y = 10x - 3
