Answer: The distance is 15
Step-by-step explanation:
To find the distance between L and Y find the difference in the x and y coordinates then square them and add them to find their square root.
-7-5= -12
0-9 = -9
12^2 + 9^2 = d^2 where d is the distance
144 + 81 = d^2
225 = d^2
d=
d= 15
Answer:
Answer C is the only one in function notation.
Step-by-step explanation:
To find something in function notation, we look for 2 different criteria.
- On the left side, it must say f( ), with a variable in the parenthesis.
- On the right side, the variable being used must match that from the left side.
Since C is the only one that satisfies both of those needs, we know it is the answer.
<h3>Answer:</h3>
A. y = -1/3x + 2 . . . . . . . . assuming a typo in your problem statement
<h3>Explanation:</h3>
The point (0, 2) is the y-intercept. This tells you the equation will be something of the form ...
... y = mx + 2 . . . . . . matching only answer choices A and C
_____
Knowing this, you can either substitute the values x=3, y=1 into these two equations to see which one works (it is not C), or you can look at the two points and determine the value of the slope.
The slope is ...
... (difference in y)/(difference in x) = (1-2)/(3-0) = -1/3 . . . . . matches choice A
The equation of the line is ...
... y = -1/3x + 2 . . . . . matches answer choice A
The equation of the parabola is
.. y = a(x +4)(x -2)
Substituting (x, y) = (6, 10) gives
.. 10 = a(6 +4)(6 -2)
The 4th selection is appropriate.
