A is at negative 1, negative 2 --------A(-1, -2)
A(-1, -2), reflect over y=x would be (-2 , -1)
(-2 , -1) , reflect across x-axis: (-2, 1)
(-2, 1) , reflect over y=x would be (1 , -2)
(1 , -2) , reflect across y-axis: (-1 , -2)
Answer is B
B) y=x, x-axis, y=x, y-axis
Answer:
see the explanation
Step-by-step explanation:
Let
c------> the number of cards in one pack of cards
we know that
After one year,
he had a total of 107 cards in his collection.
Remember that in one year there are 12 months
so
107=12c+11
Solve for c
12c=107-11
12c=96
c=96/12
c=8 cards
One pack has 8 cards
Let
x ------> the time in months
f(x) ------> the number of basketball cards in Stanley's collection
The linear equation that represent this situation is
f(x)=8x+11
Find out the number of cards after 15 years
x=15*12=180 months
substitute
f(180)=8(180)+11=1,451 cards
therefore
The domain of the function is 180 months
The range of the function is 1,451 cards
Answer:
c
Step-by-step explanation:
200.36-112.56=87.8
87.8+68.34= 156.14
26 out of 130 were marked.
Divide 26 by 130:
26/130 = 0.20
20% of the bass caught were tagged.
Now divide the total amount caught and tagged by that percentage:
258 / 0.20 = 1,290
There are 1,290 bass in the lake.
Answer:
(x -2)² +y² = 16
Step-by-step explanation:
The circle has its center at (h, k) = (2, 0), and has a radius of r = 4. The standard form equation is ...
(x -h)² +(y -k)² = r²
For the given values of (h, k) and r, this equation is ...
(x -2)² +y² = 16
