Answer:

The first option

Step-by-step explanation:

Order of operations says that you raise everything in the parentheses to the third power as the 1st step.

2m^5^3 = 8m^5*3 = 8m^15

n^4^3 = n^4*3 = n^12

They are multiplied in the original equation, so multiply those and you get 8m^15n^12

Line BC has an equation of a line Y equals 2X +3 and F has an equation of a line Y equals -1/2 x+4 these two equations represent

Masja [62]

Answer:

Lines BC and F represent perpendicular lines

Step-by-step explanation:

we have

Line BC

$y=2x+3$

the slope of the line BC is $m=2$

Line F

$y=-(1/2)x+4$

the slope of the line F is $m=-1/2$

we know that

If two lines are perpendicular, then the product of their slopes is equal to -1

$m1*m2=-1$

we have

$m1=2$ -----> slope line BC

$m2=-1/2$ -----> slope line F

Find the product of their slopes

$(2)(-1/2)=-1$

therefore

Lines BC and F represent perpendicular lines

What value of x is in the solution set of 8x 6 12+2x O-1 O 0 O 3 O 5

Sergeu [11.5K]

Step-by-step explanation:

Just consider the inequalities an equal sign and do the usual way of solving:

8x - 6 > 12 + 2x

8x - 2x > 12 +6

6x > 18

x > 3

*The only rule that you need to remember is that when you multiply or divide a negative number on both sides, then the inequality sign would be reverse.*

Example:

-x + 3 > -2

-x > -2-3

-x > -5

Multiplying both sides by -1:

x < 5
