Answer:
Given equation are:
......[1]
.....[2]
- The two lines are parallel lines then their slopes will be equal.
- When two lines are perpendicular then, the slope of lines are the negative reciprocals of each other.
Now, Equation of a line is in the form of y =mx+b where m is the slope of the line.
Slope of equation of line in [1] is;
then;
Slope of equation of line in [2];
Add both sides 2x we get;
-2x + 8y + 2x = 2x + 4
Simplify:
8y = 2x +4
Divide both sides by 8 we get;
then;
Therefore, the given two lines are neither parallel nor perpendicular.
Answer:
so the discount is 42 and the bill is $78
Step-by-step explanation:
0.35*120=42
discount is 42
120-42=78
the bill is $78
4x + 6y = 30 can be an equation.
Answer:
68
Step-by-step explanation:
Let x be the original price
The original price times the percent = 17
x*25% = 17
Change to decimal form
x*.25 = 17
Divide each side by .25
.25x/.25=17/.25
x =68
