Answer:

  JM = 7

Step-by-step explanation:

Triangles LMN and LJK are similar, so corresponding sides have teh same ratio:

  LM/MN = LJ/JK

  14/(JM+3) = (14 +JM)/15

  210 = (JM +3)(JM +14) . . . . . multiply by 15(JM +3)

  JM² +17JM -168 = 0 . . . . . . . subtract 210; put in standard form

  (JM +24)(JM -7) = 0 . . . . . . factor

The values for JM that make this true are 7 and -24. The length must be positive, so ...

  JM = 7

How can the equations of lines help you identify whether the lines are perpendicular, parallel, or nether?
Natali5045456 [20]

Answer:

We can determine whether two lines are parallel by comparing their slopes. If the slopes are the same and the y-intercepts are different, the lines are parallel. If the slopes are different, the lines are not parallel. Unlike parallel lines, perpendicular lines do intersect. Their intersection forms a right, or 90-degree, angle.

This Venn diagram shows sports played by 10 students.
seropon [69]

Answer: Option A

P(A|B)=\frac{3}{5}=0.6

Step-by-step explanation:

By Definition the probability of A given B is:

P(A|B)=\frac{P(A\ and\ B)}{P(B)}=\frac{A\ and\ B}{B}

Note that the number of students playing basketball is 6

The number of students playing soccer is 5

The number of students who play both sports is 3

Therefore we have that:

P(A|B)=\frac{3}{5}=0.6

The answer is the option A

Solve equation by using the elimination method
VladimirAG [237]
Re-write
8x + 14y = 4 (1)
-6x - 7y = -10 (2)

multiply (1) by 3 and (2) by 4
now you have
24x + 42y = 12 
-24x - 28y = -40
-------------------------add
           14y = -28
               y = -2

8x + 14y = 4
8x + 14(-2) = 4
8x - 28 = 4
8x = 32
  x = 4

answer
x = 4 and y= -2
