Answer: KX = 14 m.

Step-by-step explanation: We are given a triangle ΔJKL with medians KN,

JM and LP.

Definition : <em>The median is the segment that connects a vertex of a triangle to a midpoint on one of the triangle's sides.</em>

<em>Note: The medians of a triangle cut each other in the ratio 2:1.</em>

Therefore, for median KN, the ratio of KX and XN would be 2:1. That is

KX/XN = 2/1.

We are given KN = 21.

21 could be divided into two parts 14+7.

We can see 14 and 7 are in ratio 2:1.

Therefore, KX = 14m and XN = 7m.

So, KX = 14 m.

Graph the following y=3x-4x<br> plz help i give brainliest and points

trasher [3.6K]

Answer:

I put in a screenshot on what the graph would look like (i used desmos)

Step-by-step explanation:

Ok, you have the equation y=3-4x. This can be broken down into the y=mx+b format. -4 would be the m, and since m is the slope -4 would be the slope of your line. 3 would be your b- your y-intercept. Basically at (0,3) your line crosses the y-axis.

I hope this helps :)

4x + y = 10<br> 7x + 2y = 17

Nezavi [6.7K]

Answer:

x = 3, y = - 2

Step-by-step explanation:

By substitution method,

4x + y = 10 -------> equation 1.

7x + 2y = 17 -------> equation 2.

From equation 1,

y = 10 - 4x ------> equation 3.

Substitute equation 3 in 2,

7x + 2 ( 10 - 4x ) = 17

7x + 20 - 8x = 17

7x - 8x = 17 - 20

- x = - 3

x = 3

Substitute x = 3 in equation 1,

4 ( 3 ) + y = 10

12 + y = 10

y = 10 - 12

y = - 2

Hence,

x = 3

y = - 2

A 10-year annuity pays $1,850 per month, and payments are made at the end of each month. If the APR is 12 percent compounded mon

Fittoniya [83]

Based on the amount the annuity pays per month and the APR, the value of the annuity today is $133,349.85.

<h3>What is the present value of the annuity?</h3>

First, find the present value of the annuity at 5 years:

= 1,850 x present value interest factor of annuity, 60 months, 8/12%

= 1,850 x 49.32

= $91,242

Then find the present value of the annuity from 5 years till date:

= (1,850 x present value interest factor of annuity, 60 months, 12/12%) + ( 91,242) / (1 + 1%)⁶⁰)

= (1,850 x 44.955) + ( 91,242) / (1 + 1%)⁶⁰)

= $133,349.85
