Answer:

y = 1/2m + 2

Step-by-step explanation:

1 = -2m + c (1)

4 = 4m + c (2)

2 = -4m + 2c (1*)

(1*) + (2) = 6 = 3c

c = 2

y = mx + 2

4 = 4m + 2

2 = 4m

m = 1/2

so y = 1/2m + 2

Find the sum of this infinite geometric series where a1=0.3 and r=0.55

Lisa [10]

Hello, Marymack!

We know that in a geometric sequence defined by $\mathsf{a_1}$ and $\mathsf{r}$ , the sum can be calculated the following way:

$\mathsf{S_n = \dfrac{a_1}{1-r}}\\ \\ \\ \\ \mathsf{S_n = \dfrac{0.3}{1-0.55}}\\ \\ \\ \mathsf{S_n = \dfrac{0.3}{0.45}}\\ \\ \\ \boxed{\mathsf{S_n = \dfrac{2}{3}=0.666...}}$
