Answer:
Range is given by the second option: 
{
}.
Step-by-step explanation:
Range is the set of possible 
values in a given function.
Here, the function is defined by the following ordered pairs:
The y values of the function are {}
Therefore, the range is given as {}.
So, the second option is correct.
Answer:
Step-by-step explanation:
we know that
Triangles ABM and CDN are congruent
so
CD=AB
AB=2AL ----> because the diameter divide the circle into two equal parts
CQ=AL=140/2=70 units
NC----> is the radius
NC=148/2=74 units ----> the radius is half the diameter
Applying Pythagoras Theorem find the value of NQ
substitute the values
The equation that would best describe the situation would be the first option. To solve this question, simply break down the question into sections and then use variables X and y to represent each of the things asked for in the problem. We know the following:
X = no of tetra fish
Y = no of goldfish
If there is twice as much goldfish than tetra fish, then it would be 2y.
X = 2Y.
Then knowing what X and y represent, find the equation that gives the total cost of fish he bought, knowing that 1.50 is for a goldfish and 2.00 is for a tetra fish.
Answer:
C. (5,1)
Step-by-step explanation: You have to substitute the numbers in for x & y
A. (-4,1):
2x − y = 9
2(-4) - 1 = 9
-8 - 1
-9 = 9
NO
B. (-2,5):
2x − y = 9
2(-2) - 5 = 9
- 4 - 5 = 9
-9 = 9
NO
C. (5,1):
2x − y = 9
2(5) - 1 = 9
10 - 1 = 9
9 = 9
YES
D. (6,-3):
2x − y = 9
2(6) - - 3 = 9
12 - - 3 = 9
12 + 3 = 9
15 = 9
NO
Hope this helps you!!! :)
