Answer:
Step-by-step explanation:
a₆ = a₁r⁶⁻¹ = (-2)4⁵ = -2048
-8=2-4y
-10=-4y
y=5/2 or 2 1/2 or 2.5
Answer:
-88
Step-by-step explanation:
Let N(x) be the number of students at NMS for a certain number of years.
Let S(x) be the number of students at SMS for a certain number of years.
Let x be the number of years.
N(x)=1240-25x
S(x)=800-30x
When # of students is equal, N(x)=S(x). Therefore, we are looking for the value of x (# of years) when 1240-25x=800-30x
Subtract 1240 from each side
-25x=-440-30x
Add 30x
5x=-400
x=-88 years
