4. Find an equation for the nth term of the arithmetic sequence.
-20, -16, -12, -8, ... (2 points)
A an = -20 x 4(n - 1)
B an = -20 + 4(n - 1)
C an = -20 + 4(n + 2)
D an = -20 + 4(n + 1)

Horizontal change or the change of x

The answer is 6 weeks

One shot. if 60% of 10 is 6, then what is 70%? we know it would be seven (since 60% is mathematically 60/100, or 6/10, then 70% is 70/100, or 7/10) but we can check anyway using ratios: 6 : 60% = x : 70%*inverse multiplicationx * 60% = 6 * 70%*divide both sides by 60%x = (6 * 70%) / 60%x = 7and since he has made 6 shots already, he would need just one more to get 7 shots or 70%. if the explanation is too confusing, comment and i will try to
