ANSWER ASAP!!
Answer should only contain positive exponents .
2n/n^2
I got n/n^2 .
Answer:
[tex]\frac{2}{n}[/tex]
Step-by-step explanation:
[tex]\frac{2n}{n^2}[/tex] (exponential rule for fraction is the number subtract each other)
[tex]2n^{-1}[/tex] (from the top n exponent of 1 minus bottom exponent of2 (1-2=-1))
since the n is a -1 exponent to make it positive you put it in the denominator
[tex]\frac{2}{n}[/tex]
(the reason it's not n/n^2 is that the two cannot just disappear or be taken away unless you are solving for something and the n/n^2 can also be simplified into the 1/n)

Answer:
2x+7y=17
Step-by-step explanation:
Considering that the lower intersection is a translation of the upper intersection what does this mean about the measures of the corresponding angles
This mean about the measures of the corresponding angles the lower intersection is a translation of the upper intersection. This means that corresponding angles overlap each other on translation. So, the corresponding angles are congruent This is further explained below.
What is angles?Generally, angles is simply defined as the angle formed when two lines or surfaces meet, or the distance between them (typically measured in degrees).
In conclusion, What does this imply about the sizes of the associated angles Simply said, the bottom intersection is a literal translation of the higher one. What this indicates is that, when translated, the relevant angles overlap. As a result, the two angles are equal.

What is the midpoint between the points (3,-1) and (-9,8)?
Hey there! I'm happy to help!
To find the x value of the midpoint, you add the x values and divide by 2.
3+(-9)=3-9=-6
-6/2=-3
And for the y value you add the y values and divide by 2.
-1+8=7
7/2=3 1/2
Therefore, our midpoint is (-3,3 1/2)

Which angle relationship means two angles add up to 90
degrees?
When two angles add to 90°, we say they "Complement" each other.
So if two angles are complementary,
then the sum of their measures is 90 degrees.
For example, if we had a 62 degree angle and an 18 degree angle,
these two angles are complementary because they add to 90 degrees.

Lloyd solves the equation 24x + 18(x – 2) = 216 for x. Some of his steps are shown.
Step 1: 24+18(x−2)=216
Step 2: 24+18x−36=216
Step 3: 42x−36=216
Step 4: 42x=252
Which of the following statements BEST describes what Lloyd did to get from Step 3 to Step 4?
Answer:
24+18x-36=216
-12+18x=216
18x=216+12
18x=228
x=228/18
