Answer:
y = 8
Step-by-step explanation:
Two triangles are said to be congruent if all the three sides and three angles of both triangles are equal.
The distance between two points on the coordinate plane is given as:
[tex]Distance=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2} \\[/tex]
In triangle ABC:
[tex]|AB|=\sqrt{(2-8)^2+(6-4^2)}=\sqrt{40} =2\sqrt{10}\\\\|AC|=\sqrt{(5-8)^2+(0-4)^2}=5\\\\|BC|=\sqrt{(5-2)^2+(0-6)^2 }=\sqrt{45}[/tex]
In triangle MNO:
[tex]|MN|=\sqrt{(1-7)^2+(2-4^2)}=\sqrt{40} =2\sqrt{10}\\\\|MO|=\sqrt{(4-7)^2+(y-4)^2}\\\\|NO|=\sqrt{(4-1)^2+(y-2)^2 }[/tex]
Since triangle ABC and triangle MNO are congruent, hence:
|AB| = |MN| = 2√10, |AC| = |MO| = 5, |BC| = |NO| = √45
[tex]|AC|=|MO|=5\\\\\sqrt{(4-7)^2+(y-4)^2}=5\\\\(4-7)^2+(y-4)^2=25\\\\9 +(y-4)^2=25\\\\(y-4)^2=16\\\\square\ root\ of\ both\ sides:\\\\y-4=4\\\\y=4+4\\\\y=8[/tex]
Hence O = (4, 8)

Which equation represents the rectangular form of r = 8?
Answer:
x^2 + y^2 = 64
Step-by-step explanation:
EDGE 2020
The equation that represents the rectangular form of r = 8 is x² + y² = 64
What is rectangular form?Rectangular form, is where a complex number is denoted by its respective horizontal and vertical components.
According to the given problem,
x=rcosθ
y=rsinθ
substituting we have
x=8cosθ
y=8sinθ
Squaring and adding we obtain the
circle's origin centered equation,
x² + y² = 64
Hence, we can conclude, the equation x² + y² = 64, represents the rectangular form of r = 8.

A bag contains 4 g r e e n marbles, 8 b l a c k marbles, and 7 b l u e marbles. If a marble is drawn from the bag, replaced, and another marble is drawn, what is the probability of drawing first a g r e e n marble and then a b l u e marble
Answer:
[tex]P(Green\ and\ Blue) = 0.0776[/tex]
Step-by-step explanation:
Given
[tex]Green = 4[/tex]
[tex]Black = 8[/tex]
[tex]Blue=7[/tex]
Required
Determine the probability of selecting green then blue marble
This probability is represented as:
[tex]P(Green\ and\ Blue)[/tex]
And it is calculated using:
[tex]P(Green\ and\ Blue) = P(Green) * P(Blue)[/tex]
[tex]P(Green\ and\ Blue) = \frac{n(Green)}{Total} * \frac{n(Blue)}{Total}[/tex]
Total marble is:
[tex]Total = 4 + 8 + 7[/tex]
[tex]Total = 19[/tex]
So, we have:
[tex]P(Green\ and\ Blue) = \frac{4}{19} * \frac{7}{19}[/tex]
[tex]P(Green\ and\ Blue) = \frac{4*7}{19*19}[/tex]
[tex]P(Green\ and\ Blue) = \frac{28}{361}[/tex]
[tex]P(Green\ and\ Blue) = 0.0776[/tex] -- approximated
Hence, the required probability is approximately 0.0776

Subtract .75x from each side
8 + 1.25x-.75x = 10+.75x-.75x
8 + .5x = 10
Subtract 8 from each side
8-8 + .5x=10-8
.5x =2
Divide each side by .5
.5x/.5 = 2/.5
x = 4
