Describe how you would tell that two lines are parallel or coincide by looking at the equations of the lines in standard form.

You can tell if two lines are parallel when they have the same slope but different y-intercept. For example, y = 2x - 4 and y = 2x + 4 would be parallel lines. If they coincide, then the two lines would be on top of each other. For example, first-line with the equation of 3x +3y = 9 and second-line having 9x + 9y = 27 are coinciding lines.

x > 1.3

step by step:

8.5−0.9x> 9.8−1.9x

step 1: simplify both sides of the inequality.

−0.9x+8.5> −1.9x+9.8

step 2: add 1.9x to both sides.

−0.9x+8.5+1.9x> −1.9x+9.8+1.9x

1x+8.5> 9.8

step 3: subtract 8.5 from both sides.

1x+8.5−8.5> 9.8−8.5

1x> 1.3

step 4: divide both sides by 1.

1x/1 > 1.3/1

30 feet

step-by-step explanation:

that would be 2 1/2 * 12

= 24 + 6

= 30 feet   (answer)
