Answer:

The answers to the first question are A,C,D

The answer to the second question is YZ=16

Step-by-step explanation:

(1st Question)

Since <K and <M Are equal, and both <L's are equal, KL and ML are congruent (Answer choice) because of the ASA postulate.

You need to create the following equation to find the length of KN and MN 7x-4=5x+12

(Get the "x" variable to one side)

2x-4=12

(Isolate the variable)(Remove the 4)

2x=16

(Divide the 2 by itself to remove it from the x, remember to divide both sides by 2)

x=8 (Answer Choice)

Plug in the x value into each equation

KN= 7(8)-4

KN= 56-4

KN= 52

MN= 5(8)+12

MN= 40+12

MN= 52 (Answer Choice)

MN=KN

(Second Question)

Since XWY(20) is half of XWZ(40), ZWY also equals 20.

This now proves the triangle is congruent by the AAS postulate.

Since the triangles are congruent, if XY = 16, YZ also equals 16.

How do you solve 5(N+4)/3 = N-8

Dmitriy789 [7]

Answer:

n=-22

Step-by-step explanation:

rewrite the equation as 5(n+4) = n-8

now distribute the 5 through the parentheses 5n+20 = n-8

multiply each side by 3 5n+20=3n - 24

subrtact 3n from both sides 5n+20=3n - 24

-3n -3n

2n+20=-24

then subtract 20 from each side 2n +20=-24

-20 -20

Giving you 2n=-44 then divide both sides by 2

2n=-44 Giving you n=-22

(-5, 4), (8,-6) help me please.. I don't know anything about geometry

Tom [10]

Answer:

Distance= 16.4 units

Midpoint= (1½, -1)

Step-by-step explanation:

$\boxed{distance \: between \: 2 \: points = \sqrt{ {(x1 - x2)}^{2} + {(y1 - y2)}^{2} } }$

Distance between (-5, 4) and (8, -6)

$= \sqrt{ {( - 5 - 8)}^{2} + {[4 - ( - 6)]}^{2} }$

$= \sqrt{ {( - 13)}^{2} + (4 + 6) {}^{2} }$

$= \sqrt{169 + 10^{2} }$

$= \sqrt{169 + 100}$

$= \sqrt{269}$

= 16.4 units (3 s.f.)

$\boxed{midpoint = ( \frac{x1 + x2}{2} , \frac{y1 + y2}{2} )}$

Midpoint

$= ( \frac{8 - 5}{2} , \frac{ - 6 + 4}{2} )$

$= ( \frac{3}{2} , \frac{ - 2}{2} )$

$= ( 1\frac{1}{2} , - 1)$

Which function best fits the following points?

Rudik [331]

Answer:

Correct answer is choice B.

Step-by-step explanation:

We have been given a graph and 4 different choices.

Now we need to determine about which of the given functions best fits the points in the graph.

From graph we can clearly see that points are going upward very fast as compared to x when x-value increases.

That happens in exponential type function which is usually written in form of

$y=ab^x$

Choice B looks similar to that.

hence correct answer is choice B.
