Find x.<br> 8x + 11<br> 12x - 1

ELEN [110]

Answer:

x = 3

Step-by-step explanation:

If T is the midpoint, that means segments ST and TU are congruent.

Step 1: Set up expression

8x + 11 = 12x - 1

Step 2: Solve

11 = 4x - 1

12 = 4x

x = 3

Using mathematical induction prove whether or not the following statement is true for all positive integers n, or show why it is

aniked [119]

Base case: For $n=1$ , the left side is 2 and the right is $2\cdot1^2=2$ , so the base case holds.

Induction hypothesis: Assume the statement is true for $n=k$ , that is

$2+6+10+\cdots+4k-2=2k^2$

We want to show that this implies truth for $n=k+1$ , that

$2+6+10+\cdots+4k-2+4(k+1)-2=2(k+1)^2$

The first $k$ terms on the left reduce according to the assumption above, and we can simplify the $k+1$ -th term a bit:

$\underbrace{2+6+10+\cdots+4k-2}_{2k^2}+4k+2$

$2k^2+4k+2=2(k^2+2k+1)=2(k+1)^2$

so the statement is true for all $n\in\mathbb N$ .

Answer: $m\angle 2+m\angle 5=180^{\circ}$

Step-by-step explanation:

You are ending by proving $\angle 2$ and $\angle 5$ are supplementary, so right before that, you need to prove their measures add to 180 degrees.
