Rufina [12.5K]
<h2>Lisa and Ann ate 3/4 of the box together</h2>

<em><u>Solution:</u></em>

Given that,

Lisa and Ann are eating a box of crackers

Lisa\ ate = \frac{3}{6}\\\\Ann\ ate = \frac{1}{4}

<h3><u>How much of the box did the two girls eat together?</u></h3>

Together\ eaten = Lisa\ ate + Ann\ ate\\\\Together\ eaten = \frac{3}{6} + \frac{1}{4}\\\\Together\ eaten = \frac{1}{2} + \frac{1}{4}\\\\Together\ eaten = \frac{1 \times 2}{2 \times 2} + \frac{1}{4}\\\\Together\ eaten = \frac{2}{4} + \frac{1}{4}\\\\Together\ eaten = \frac{3}{4}

Thus Lisa and Ann ate 3/4 of the box together

A function f is defined by f(x) = 1 + 6x + x2 + 6x3 + x4 + ⋯ that is, its coefficients are c2n = 1 and c2n + 1 = 6 for all n ≥ 0
Alenkinab [10]

From the odd-degree terms, take out one copy and rewrite the series as

1+6x+x^2+6x^3+\cdots=(1+x+x^2+x^3+\cdots)+5x+5x^3+\cdots

1+6x+x^2+6x^3+\cdots=(1+x+x^2+x^3+\cdots)+5x(1+x^2+\cdots)

Then if |<em>x</em>| < 1, we can condense this to

\displaystyle\sum_{n=0}^\infty x^n+5x\sum_{n=0}^\infty x^{2n}=\frac1{1-x}+\frac{5x}{1-x^2}=\frac{1+6x}{1-x^2}

Since the series we invoked here converge on -1 < <em>x</em> < 1, so does this one.

Q1: Find the slope of the line passing through the pairs of points and describe
AlladinOne [14]

Answer:

m=0

horizontal line

Step-by-step explanation:

Given two points, we can find the slope from

m = (y2-y1)/(x2-x1)

   = (1-1)/(-3-2)

   =0/-5

The slope is 0

The line is horizontal
