Answer:
D
Step-by-step explanation:
If the cost is the y-axis (said in question) it would be narrowed down to B and D. But since the rate of change is constant and will be the same, the line would be countinuous making D be the right answer.

Two groups of people went to see Avatar in IMAX 3‐D. The first group spent $33.00 on two adult and three children tickets. The other group spent $55.00 on five adult and two children tickets. Let x represent the cost of an adult ticket and y represent the cost of a children ticket. Answer each of the questions. Label each answer.
1) What is the equation that represents the first group spending?
2) What is the equation that represents the second group spending?
3) What is the cost for each type of ticket (the adult and the children)? Show your work.
Answers
Answer: An adult’s ticket costs $9 while a children’s ticket costs $5.
Step-by-step explanation:
1). 2x + 3y = 33
2). 5x + 2y = 55
3). I’m going to use substitution.
Isolate a variable (x):
2x + 3y = 33
2x = -3y + 33
X = (-3y + 33)/2
X = -3/2y + 33/2
Substitute and solve for y:
5x + 2y = 55
5(-3/2y + 33/2) + 2y = 55
-15/2y + 165/2 + 2y = 55
-11/2y = -55/2
Y = 5 <— children’s ticket.
Solve for x:
2x + 3y = 33
2x + 3(5) = 33
2x + 15 = 33
2x = 18
X = 9 <— adult’s ticket.
Check:
5x + 2y = 55
5(9) + 2(5) = 55
45 + 10 = 55
55 = 55
2x + 3y = 33
2(9) + 3(5) = 33
18 + 15 = 33
33 = 33

BC is 40.8
B° is 59.03°
C° is 30.96°
Step-by-step explanation:
classic pythagoras (a² + b² = c²)
35² + 21² = 1666
sqrt1666 = 40.8
you do tan(x) here because you want to find B° and only know the opposite and adjacent sides.
35/21 = 1.66...
tan-¹(1.66..) = 59.03°
you do tan(x) here because you want to find C° and only know the opposite and adjacent sides.
21/35 = 0.6
tan-¹(0.6) = 30.96°

Step-by-step explanation:
So since it's a line, they will equal 180. So since angle 7 is half of 8 we need to a pair of numbers that add to 180. So you can find out that 120/2 is 60. Then 60+120=180

Answers
Answer:
x = 46
Step-by-step explanation:
Here, we want to get the value of the angle marked x
From the diagram given , the two angles that are other than x can be gotten from the value of their supplements
Angles on a straight line are supplementary as they add up to 180
Thus, mathematically;
(180-130) + (180-96) + x = 180
50 + 84 + x = 180
x = 180-50-84 = 46

A They are parallel because they have the same slope of −2.
B They are parallel because they have the same slope of one half.
C They are lines that lie exactly on top of one another because they have the same slope and the same y-intercept.
D They are lines that lie exactly on top of one another because they have the same slope and a different y-intercept.
Answers
Answer:
C. They are lines that lie exactly on top of one another because they have the same slope and the same y-intercept.Step-by-step explanation:
Given lines
6x + 3y = 12 ⇒ 2x + y = 4 ⇒ y = -2x + 44x + 2y = 8 ⇒ 2x + y = 4 ⇒ y = -2x + 4The lines are same as both have same slope and y-intercept.
