Are the graphs of the lines in the pair parallel? explain. y = 5x + 6 –18x + 3y = –54 no, since the y-intercepts are different. no, since the slopes are different. yes, since the slopes are the same and the y-intercepts are the same. yes, since the slopes are the same and the y-intercepts are different.

No, since the slopes are different.

Step-by-step explanation:

When the lies are parallel then the slopes are equal.

Lets find out slope of each equation and check

For equation of a line , where m is the slope

Slope of first equation = 5

solve for y

Add 18x on both sides

Divide both sides by 3

Slope of second equation = 6

Slope of both equations are not same , so they are not parallel.

No, since the slopes are different.

18.8 cubic inches.

step-by-step explanation:

volume of a cone = πr²h

r = 1.5 inches

h = 8 inches

pi = 3.14

volume of our cone = × 3.14 × 1.5² × 8 = 18.84 square inches

or equals to 18.8 square inches rounded up to nearest tenth.
