The vertices of parallelogram ABCD are A(2,1),B(3,4),C(5,3), and D(4,0). ABCD is reflected over the x-axis to create parallelogram QRST. What are the coordinates of QRST?A
Q(−2,1),R(−3,4),S(−5,3),T(−4,0)
B
Q(−2,−1),R(−3,−4),S(−5,−3),T(−4,0)
C
Q(1,2),R(4,3),S(3,5),T(0,4)
D
Q(2,−1),R(3,−4),S(5,−3),T(4,0)
Answers
Answer:
The correct answer is:
D) Q(2,1) R(3,-4) S(5,-3) T(4,0)
Step-by-step explanation:
When you reflect over the x-axis the vertices of the parallelogram, the y -coordinates is multiplying by -1.
Then the new coordinates of the parallelogram are:
Q(2,-1) R(3,-4) S(5,-3) T(-4,0)

Answer: Probability that they will both occur is 25%.
Step-by-step explanation:
Since we have given that
There are two non simultaneous events.
Probability of each event = 50%
Since both are independent to each other.
Let A and B be two events.
We need to find the probability that they will both occur i..e P(A∩B).
As we know the rule of independence of events:
Hence, Probability that they will both occur is 25%.

Step-by-step explanation:
180=85+44+60+(x)-9
Answer:
A. -9
Step-by-step explanation:
A triangle equals 180 degrees so:
60 + 85 + x + 44 = 180
add like terms
x + 189 = 180
subtract 189 from both sides
x = -9

Answer: 6 feet
Step-by-step explanation:
Hi, to answer this question we have to apply the next formula:
Volume of a cone= (1/3) π radius² height
Replacing with the values given and solving for r:
36π = (1/3) π r² 12
36π/ [(1/3) π 12]= r²
9 = r²
√9 =r
3 ft = r
Since:
Diameter = 2 x radius
Substituting r=3
D = 2x 3
D = 6 feet

move y by itself
7x+5y=20
minus 7x from both sides
7x-7x+5y=20-7x
0+5y=20-7x
5y=20-7x
divide both sides by 5
5y/5=(20-7x)/5
y=(20-7x)/5
y=(20/5)+(-7x/5)
