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

Find a. Roud to the nearest tenth:<br> 2cm<br> 15*<br> a<br> 105*<br> c
MariettaO [177]

Answer:

So since we use law of sines. We can get 2 fractions equal to eachother but first we need to solve for missing angle. That would be 180-105-15 = 60

So now we can get a fraction. So that means that sin(105)/2 = sin(60)/a

Then we do recipricol. 2/sin(105) = a/sin(60)

multiply by sin(60) both sides.

2sin(60)/sin(105) = a

round and solve and we get a is equal to

1.7931 or 1.8

PLEASE HELP ME WITH MY PROBLEM!!! 50 POINTS!!!
Molodets [167]

Well he started off right by solving for y=y to find the abscissa of the intersection points between the two points,but then he assumed that their ordinate (y coordinates) are both zero,which is incorrect obviously. To find their ordinate,all we have to do is plug the x values into any of the two equations, since they both will pass through that point ੴ

y = 4 x+ 1 \\ y = 4(3) + 1  \\ y = 12 + 1 \\ y = 13

y = 4x + 1 \\ y = 4( - 2) + 1 \\ y =  - 8 + 1 \\ y =  - 7

I chose to plug the values in the second linear equation, since it's easier to compute
