Answer:
A. Right angle -- if you multiply the slopes of 2 intersecting lines and you "-1" then the lines are perpendicular - in this case the line in quadrant 3 has a slope of "1" and the line in quadrant 4 has a slope of "-1", hence their product is "-1" and the angles formed at the intersection of the lines are right angles.
Step-by-step explanation:
Answer:
There are 2 ters because you would distribute the 19 to the a and the b to make it 19a + 19b, which has 2 terms
3u+ 9 is the right answer, since thier not like terms you can’t add them
Let the amount of adult tickets sold be x
Since the total of 380 tickets sold consists of the amount of adult tickets and the amount of children tickets that are 70 fewer:
x + (x - 70) = 380
2x - 70 =380
2x = 450
x = 225
Therefore, the amount of adult tickets sold is 225
1/7x-6=3/7x+4
+6 +6
1/7x=3/7x+10
-3/7x -3/7x
-2/7x=10
x= -35
