#6

  • x-y=-2
  • y=x+2

Ordered pairs

  • (0,2)
  • (1,3)
  • (2,4)

And

  • x-y=2
  • y=x-2

Ordered pairs

  • (1,-1)
  • (2,0)
  • (-2,-4)

Remember parallel lines have no solutions

Answer:

Step-by-step explanation:

<u>Given system of equations</u>

\textsf{Equation 1}:\quad x-y=-2

\textsf{Equation 2}:\quad x-y=2

Rewrite each equation to make y the subject.

Input x = 0 into the equation to find the y-intercept.

Input y = 0 into the equation to find the x-intercept.

Input x = 4 into the equation to find a third ordered pair.

Plots the points on the graph and draw a line through them.

<u>Equation 1</u>

\begin{aligned}x-y &=-2\\ \implies -y&=-x-2\\y&=x+2\end{aligned}

x=0 \implies y=0+2=2 \implies (0,2)

y=0 \implies x+2=0 \implies x=-2 \implies (-2,0)

x=4 \implies y=4+2=6 \implies (4,6)

<u>Equation 2</u>

\begin{aligned}x-y& =2\\\implies -y &=-x+2\\y & = x-2\end{aligned}

x=0 \implies y=0-2=-2 \implies (0,-2)

y=0 \implies x-2=0 \implies x=2 \implies (2,0)

x=4 \implies y=4-2=2 \implies (4,2)

Slope-intercept form of a linear equation:  y=mx+b

(where m is the slope and b is the y-intercept)

Comparing both equations:

  • Same slopes
  • Different y-intercepts

Therefore, the lines are parallel. This is called <u>Inconsistent</u> and means the system of equations has <u>no solution</u> (since the lines never intersect).

Mandarinka [93]
\begin{matrix}1\\1&1\\1&2&1\\1&3&3&1\\1&4&6&4&1\end{bmatrix}

The rows add up to 1,2,4,8,16, respectively. (Notice they're all powers of 2)

The sum of the numbers in row n is 2^{n-1}.

The last problem can be solved with the binomial theorem, but I'll assume you don't take that for granted. You can prove this claim by induction. When n=1,

(1+x)^1=1+x=\dbinom10+\dbinom11x

so the base case holds. Assume the claim holds for n=k, so that

(1+x)^k=\dbinom k0+\dbinom k1x+\cdots+\dbinom k{k-1}x^{k-1}+\dbinom kkx^k

Use this to show that it holds for n=k+1.

(1+x)^{k+1}=(1+x)(1+x)^k
(1+x)^{k+1}=(1+x)\left(\dbinom k0+\dbinom k1x+\cdots+\dbinom k{k-1}x^{k-1}+\dbinom kkx^k\right)
(1+x)^{k+1}=1+\left(\dbinom k0+\dbinom k1\right)x+\left(\dbinom k1+\dbinom k2\right)x^2+\cdots+\left(\dbinom k{k-2}+\dbinom k{k-1}\right)x^{k-1}+\left(\dbinom k{k-1}+\dbinom kk\right)x^k+x^{k+1}

Notice that

\dbinom k\ell+\dbinom k{\ell+1}=\dfrac{k!}{\ell!(k-\ell)!}+\dfrac{k!}{(\ell+1)!(k-\ell-1)!}
\dbinom k\ell+\dbinom k{\ell+1}=\dfrac{k!(\ell+1)}{(\ell+1)!(k-\ell)!}+\dfrac{k!(k-\ell)}{(\ell+1)!(k-\ell)!}
\dbinom k\ell+\dbinom k{\ell+1}=\dfrac{k!(\ell+1)+k!(k-\ell)}{(\ell+1)!(k-\ell)!}
\dbinom k\ell+\dbinom k{\ell+1}=\dfrac{k!(k+1)}{(\ell+1)!(k-\ell)!}
\dbinom k\ell+\dbinom k{\ell+1}=\dfrac{(k+1)!}{(\ell+1)!((k+1)-(\ell+1))!}
\dbinom k\ell+\dbinom k{\ell+1}=\dbinom{k+1}{\ell+1}

So you can write the expansion for n=k+1 as

(1+x)^{k+1}=1+\dbinom{k+1}1x+\dbinom{k+1}2x^2+\cdots+\dbinom{k+1}{k-1}x^{k-1}+\dbinom{k+1}kx^k+x^{k+1}

and since \dbinom{k+1}0=\dbinom{k+1}{k+1}=1, you have

(1+x)^{k+1}=\dbinom{k+1}0+\dbinom{k+1}1x+\cdots+\dbinom{k+1}kx^k+\dbinom{k+1}{k+1}x^{k+1}

and so the claim holds for n=k+1, thus proving the claim overall that

(1+x)^n=\dbinom n0+\dbinom n1x+\cdots+\dbinom n{n-1}x^{n-1}+\dbinom nnx^n

Setting x=1 gives

(1+1)^n=\dbinom n0+\dbinom n1+\cdots+\dbinom n{n-1}+\dbinom nn=2^n

which agrees with the result obtained for part (c).
