∑ from 1 to infinity of 12(3/5)^(i - 1)
Since the common ratio is less than 1, the series is convegent. [i.e. 3/5 < 1]
Sum to infinity of a geometric series is given by a/(1 - r); where a is the first term, and r is the common ratio.
Sum = 12/(1 - 3/5) = 12/(2/5) = 30.
x+y=64 and x-y=16 can be used to solve the system.
Step-by-step explanation:
Let,
x,y be the two shirts.
According to given statement;
Bob spent $64 on both shirts;
x+y=64 Eqn 1
The difference between the costs of the shirts was $16 means subtraction;
x-y=16 Eqn 2
x+y=64 and x-y=16 can be used to solve the system.

Answer:
I may be able to help you I need a image though
The slope intercept form for this line would be in the form of y=mx+b. The slope is m and the y-intercept is b.
y = (slope)x + (y-intercept)
y = 2x - 3
So, the answer is C.
Hope I could help! Have a good one!
