Answer:
1. A, C, and D are on the line.
1st graph:
1. The slope is 2/3.
2. The y-intercept is (0, -1)
3. The equation is y = 2/3x - 1
2nd graph:
1. The slope is 4.
2. The y-intercept is (0, -3)
3. The equation is y = 4x - 3
Step-by-step explanation:
Answer: Tickets cost $25 and each person must contribute $2 for the bus. There are 52 people going on the trip.
Step-by-step explanation:
Given: Mr. Bartley is taking the theater club on a field trip [which must include bus or other vehicle] to see the musical wicked. The school treasurer asked Mr. Bartley for the group's total ticket cost.
He wrote the following cost function for the school treasurer.
Total Cost =52(25+2)
Since cost function is a function based on number of people and per head cost.
So, the statement which best describe the cost function is "Tickets cost $25 and each person must contribute $2 for the bus. There are 52 people going on the trip."

Answer: choice C) 15</h3>
Simplify the left side to get
2(4+x)+(13+x)
2(4)+2(x) +13+x
8+2x+13+x
3x+21
------------
So the original equation
2(4+x)+(13+x) = 3x+k
turns into
3x+21 = 3x+k
------------
Subtract 3x from both sides
3x+21 = 3x+k
3x+21-3x = 3x+k-3x
21 = k
k = 21
-----------
If k = 21, then the original equation will have infinitely many solutions. This is because we will end up with 3x+21 on both sides, leading to 0 = 0 after getting everything to one side. This is a true equation no matter what x happens to be.
If k is some fixed number other than 21, then there will be no solutions. This equation is inconsistent (one side says one thing, the other side says something different). If k = 15, then
3x+21 = 3x+k
3x+21 = 3x+15
21 = 15 .... subtract 3x from both sides
The last equation is false, so there are no solutions here.
note: if you replace k with a variable term, then there will be exactly one solution.
