Identify the equations as parallel lines, perpendicular lines, or neither. Equation 1: -3x + y = 7 Equation 2: 3y = -x -3

A. Perpendicular
B. Parallel
C. Neither

B. Parallel

Step-by-step explanation:

Equation 1 simplified:   y = 3x+7

Equation 2 simplified: y = -x/3-3

The slopes are completely different, ruling out the possibility of the lines being parallel.

But we also see the slopes of the equations are opposite and negative to each other. Making the lines perpendicular.

phosphate, calcium ion, chloride ion, neon atom

step-by-step explanation:

first anwser choice.

step-by-step explanation:

the greater/less or equal to symbol (> or < with the line at the bottom) is a closed/filled in circle.

-5c + 2 _< _27

subtract from both sides by 2

-5c _< _ 27

divide both sides by -5

c _< _ 5.4

flip the inequality sign

c _> _5.4

the only possible answer that would match the simplified inequality is the first answer choice
