# Answer on Linear Algebra Question for robb

Question #13036

algebraically, find the intersection points of the two lines given in each part of this problem. y=0.12x+18 y=0.08x+25

Expert's answer

To find intersection point we need to equate right parts of given expressions:

0.12x+18=0.08x+25

0.12x-0.08x=25-18

0.04x=7

x=7/0.04=175

To find corresponding value of y we should substitute obtained x into any of the expressions:

y=0.12*175+18=21+18=39

So the intersection point is (175,39)

0.12x+18=0.08x+25

0.12x-0.08x=25-18

0.04x=7

x=7/0.04=175

To find corresponding value of y we should substitute obtained x into any of the expressions:

y=0.12*175+18=21+18=39

So the intersection point is (175,39)

5=5

9=3*3=3<sup>2</sup>

Therefore LCM(5,9)=5*3<sup>2</sup>=45
