4 0

Answer:

-0.7

Step-by-step explanation:

First do 3.2-1.8= 1.4. So now we know that -2n=1.4. Next you solve for n to get the answer of -0.7 with your answer of the third option.

Given: KL || MN Prove: KM/JM = LN/JL
jeka94

Answer:

See the bolded parts below. It corresponds to the blanks we have to fill in for each step.

Step-by-step explanation:

Taking a look at the figure, we see that KL ║ MN, ( which is given, as you can see ) while MJ and NJ act each as a transversal. This is a key point that will help us.

2. For step 2, we see that ∠JKL ≅ ∠JMN, while ∠JLK ≅ ∠JNM. This is true is they are present as corresponding angles, on either transversal. We can fill in this blank with " Corresponding angles. "

3. Therefore, for this 3rd step triangles JKL and JMN will be similar by " angle angle similarity. " After all, ∠JKL ≅ ∠JMN / ∠JLK ≅ ∠JNM.

4. This step can be proved by the " Proportionality of Corresponding Parts in Similar Triangles. " As you can see, the triangles are similar - and hence their parts correspond to one another.

5. I believe you mean step 5 to be " JM = JK + KM and JN = JL + LN. " That being said this is true by the " Partition Postulate, " which states that a whole is composed of it's parts.

6. This step substituted the 5th step into the 4th step. Therefore, it can be stated as " Substitute step 5 ➡ step 4. "

7. And for this last step here you can say " Simplify further. "

Find the indicated limit, if it exists.
Luda [366]
Find {\displaystyle\lim_{x \rightarrow ~-8}f(x)}

where { f(x) =   \begin{cases}  & x+9,~~~~~~~~~~{\large x\ \textless \ -8} \\   & -7-x,~~~~~~{\large x\ge-8} \end{cases}     }

<span>So to find the left sided limit, you need to plug in -8, into x+9 and to find the right sided limit, you need to plug in -8, into -7-x.
</span>
<span>If the two sides of the limit are no equivalent, then </span>{\displaystyle\lim_{x \rightarrow ~-8}f(x)~~DNE}

Since both sides are equal to 1, the limit is 1.
