A function on a graph to figure it out you can do the line test where you draw a line through the graph and if the line touches two points its not a function. With this in mind bottom right is for sure one and the top left looks like one but i cant really tell...
Step-by-step explanation:
Answer:
it arrives at 1:45
Step-by-step explanation:
since it is 10:40, we will ad 3 hours, 11, 12, 1.
Then, we still have the 40, and will have to add the 5 minutes because of the 3 hours and 5 minutes.
Giving us, 1:45
Answer/Step-by-step explanation:
Part A:
Evidence 1: the line passes through the point of origin, (0, 0)
Evidence 2: it has a unit rate or constant of proportionality, k = y/x = 5/3
Part B:
When extended, if the ray passes through the point, (18, 30), then y/x of this point, should give us the same unit rate (k) of 5/3 of the graph.
Thus:
y/x = 30/18
Simplify
= 5/3
Thus, it has the same unit rate of the graph, therefore, the ray passes through the point (18, 30).
(A) (B)
4------------------7
4------------------7
4------------------7
-------------------------
Total (A)=4+4+4=12
Total (B)=7+7+7=21
Total (A) + Total (B)=12+21=33
-------------------------
(4+7)+(4+7)+(4+7)=11+11+11=33
Answer:
3x + 4y = - 20
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Here m = - 
, thus
y = - x + c ← is the partial equation
To find c substitute (- 8, 1) into the partial equation
1 = 6 + c ⇒ c = 1 - 6 = - 5
y = - x - 5 ← in slope- intercept form
Multiply through by 4 to clear the fraction
4y = - 3x - 20 ( add 3x to both sides )
3x + 4y = - 20 ← in standard form
