Answer:
x=7
Step-by-step explanation:
Step 1: Subtract 4x from both sides.
x+30−4x=4x+9−4x
−3x+30=9
Step 2: Subtract 30 from both sides.
−3x+30−30=9−30
−3x=−21
Step 3: Divide both sides by -3.
−3x
−3
=
−21
−3

Answer:
(-12, 5), (12, -5)
Step-by-step explanation:
Reflection across the origin is the transformation ...
(x, y) ⇒ (-x, -y)
Look for coordinates that are the opposites of their counterparts. You will find the appropriate answer choice is ...
(-12, 5), (12, -5)
You have to divide 784 by 93 so when you do it you get 8.43 which is rounded about 8
Hope this helps =)
Answer:
2/9
Step-by-step explanation:
For the first draw:
We have,
Number of blue marbles (B)= 5
Total number of marbles (N)= 10
Probability of drawing a blue marble in first
draw [P(B)] = B/N
=5/10
=1/2
For the second draw when the initially drawn blue marble is not placed back in the bag:
We have,
Number of blue marbles (b) = 4
Total number of marbles (n) = 9
Probability of drawing a blue marble in the second draw [P(b)] = b/n
= 4/9
Finally,
Probability of drawing two blue marbles
[P(Bb)] = [P(B)] * [P(b)]
= 1/2 * 4/9
=2/9
Therefore, [P(Bb)] = 2/9
