Line bc is represented by 3x + 2y =8 line ad is a represented by -3 x -2y =6 what is the relationship of line bc to line ad expl

Vlad1618 [11]

Answer:

Parallel lines

Step-by-step explanation:

Line BC:

$3x + 2y =8$

Line AD:

$-3x - 2y =6$

Adding both equations, in this case, gives us the point at which the lines intersect:

$3x + 2y-3x-2y =8+6\\0=14$

Since zero will never equal fourteen, the equation above means that lines BC and AD will never intersect. When two lines have no point in common, they are said to be parallel lines.

During a weekend trip, Ashley will drive a 150 miles of the 200 mile road trip, what percent of the total mile age will she driv

madreJ [45]

It is simple, you are converting 150 of 200 into a fraction and reducing it

150/200=15/20

5 goes into 20 4 times

15/20=1/4

1/4=0.75=75%

What is 125^2/3 in simplest form? and What is \sqrt[5]({-245} ) ^{5} in simplest form?

Natasha_Volkova [10]

${ 125 }^{ \frac { 2 }{ 3 } }\\ \\ ={ \left( { 125 }^{ \frac { 1 }{ 3 } } \right) }^{ 2 }\\ \\ ={ \left( \sqrt [ 3 ]{ 125 } \right) }^{ 2 }\\ \\ ={ 5 }^{ 2 }\\ \\ =25$

This is because:

${ a }^{ \frac { m }{ n } }\\ \\ =\sqrt [ n ]{ { a }^{ m } }$

Remember that:

5 x 5 x 5 = 125
