Answer: A. A relation that is a function.
Step-by-step explanation:
A relation is said to be a function if each input value is associated with one unique output value.
Here, Number of miles run by car is directly proportional to the quantity of gasoline.
Independent variable - quantity of gasoline.
Dependent variable - Number of miles
On assuming the condition of car as good, the number of miles a car can run highly depends on the gallons of gasoline in the tank .
As quantity of gasoline increases number of miles driven would also increases.
i.e. Number of miles driven is a function with respect to quantity of gasoline.
Hence, the given line best describe as : A relation that is afunction.
Answer:
The answer is - 60
Step-by-step explanation:
19^2 + x^2 = 21^2
19^2 = 361
21^2= 441
361 + x^2 = 441
x^2 = 441-361 = 80
x = sqrt(80) = 8.944 round to nearest tenth = 8.9
Answer:
y-1 = 5/3(x-3)
Choice C
Step-by-step explanation:
slope = (y2-y1)/(x2-x1)
(3,1) (6,6)
m = (6-1)/(6-3)
m = (5/3)
the point slope form of a line is given by
y-y1 = m(x-x1)
You have point (3,1)
y-1 = 5/3(x-3)
Choice C
Answer:
-3x x(2x²+4x-3)
