Answer:

The point that lies on the line parallel to line KL would be ( 8, - 10 )

Step-by-step explanation:

Line KL passes through the points ( - 6, 8 ) and ( 6, 0 ) while it's respective parallel line passes through point M, ( - 4, - 2 ).

Our approach here is to first determine the slope of KL such that the slope of it's parallel line will be the same, and hence we can determine a second point on this line.

Slope of KL : ( y₂ - y₁ ) / ( x₂ - x₁ ),

( 0 - 8 ) / ( 6 - ( - 6 ) ) = - 8 / 6 + 6 = - 8 / 12 = - 2 / 3

Slope of respective Parallel line : - 2 / 3,

Another point on Parallel line : ( 8, - 10 )

How can we check if this point really belongs to the parallel line? Let's take the slope given the points ( - 4, - 2 ) and ( 8, - 10 ), and check if it is - 2 / 3.

( y₂ - y₁ ) / ( x₂ - x₁ ),

( - 10 - ( - 2 ) ) / ( 8 - ( - 4 ) ) = ( - 10 + 2 ) / ( 8 + 4 ) = - 8 / 12 = - 2 / 3

And therefore we can confirm that this point belongs to line KL's parallel line, that passes through point M.

Triss [41]

Answer:

2029

Step-by-step explanation:

We can write an equation:

0.28+0.006x=0.51

A few things explained:

The constant 0.28 comes from the fact in 1990, 28% of babies were born to parents who were not married. 28%=0.28

0.006 represents 0.6% and x represents the number of years will pass until 49% of babies will be born out of wedlock

0.51 represents 51%. 51% represents the percentage of babies who will be born to parents not married (100% - 49%=51%). You want to use 51% instead of 49% because the right side represents the babies born to parents not married.

We can solve the equation:

0.28+0.006x=0.51

0.006x=0.23

x=38.33

Since you can't have 38.3333 years, we'll say that 39 will pass until 49% of babies are born out of wedlock.

So, we add 39 years to 1990.

1990+39=2029

Hope this helps!

Write the equation of the circle with center (3,2) and with (9,3) being a point on the circle
miss Akunina [59]

Answer:

(x-3)^2 + (y-2)^2 = 37

Step-by-step explanation:

To write the equation of a circle, use the formula (x-h)^2+(y-k)^2 = r^2 where the center of the circle is (h, k).

This means the equation is (x-3)^2 + (y-2)^2 = r^2.

Find the radius r by finding the distance between (3,2) and (9,3) using the distance formula.

d = \sqrt{(9-3)^2 + (3-2)^2} =\sqrt{6^2 + 1^2} =\sqrt{36+1} =\sqrt{37}

Since the radius is √37 and therefore r^2 = 37.

The equation is (x-3)^2 + (y-2)^2 = 37.

PLS HELP 75 POINTSSSSSSSSS WILL MARK BRAINLIEST!!!!!!
Julli [10]

Answer:

Step-by-step explanation:

3x - 4y = 9...........(1)

2x + 8y = 6..........(2)

Multiply (1) by 2 and (2) by 3

6x - 8y = 18.........(3)

6x + 24y = 18......(4)

Subtracting (3) from (4)

24y - (-8y) = 18 - 18

24y + 8y = 0

32y = 0

y = 0/32

y = 0

Substituting y = 0 into (1)

3y - 4y = 9

3y - 4(0) = 9

3y = 9

y = 9/3

y = 3
