Step-by-step explanation:
Let <em>f(x)</em> be the sum of the geometric series,

for |<em>x</em>| < 1. Then taking the derivative gives the desired sum,

Answer:
126?
Step-by-step explanation:
sense there are 3 cartons and 42 in each carton you would multiply 3 by 42 to get 126.
Answer:
11
Step-by-step explanation:
Two negatives cancel each other out and makes the equation 9+2. 9+2 equals 11.
Answer:
y = 2x + 4
Step-by-step explanation:
Two points on this line are (-2, 0) and (0, 4). Going from the first to the second, x increases by 2 (this is the 'run') and y increases by 4 ('rise').
Thus, the slope of this line is m = rise / run = 4/2 = 2
Using the slope-intercept formula, we get y = mx + b = 2x + b
Let x = -2 and y = 0 to find b: 0 = 2(-2) + b, so b = 4, and the desired equation is then:
y = 2x + 4
