Let point L be between M and N on MN. Given that MN=31, ML= h-15 and LN = 2h-8. Find LN

Answers

Answer 1

Answer: Since point L is merely found on the line MN, ML and LN are considered to be line segments. So adding both line segments should add up to line MN's total length which is 31 units. We can use the given relations to create a mathematical equation as follows:

Given: MN = 31; ML = h - 15; LN = 2h - 8

MN = ML + LN

Substituting the given values:
31 = h - 15 + 2h - 8
31 = 3h - 23

It is necessary to solve for the value of h. To do this, we must isolate h and solve for it:

Adding 23 to both sides of the equation:
31 + 23 = 3h - 23 + 23
54 = 3h
h = 18

Substituting the value of h to the equation of LN we get the following:
LN = 2(18) - 8
LN = 36 - 8
LN = 28

Therefore the value of LN is 28.

Write an equation that is parallel to 3x- 2y = 14 and passes through the point (-6, -11).

Answers

Answer:

Y=3/2x-2

Step-by-step explanation:

turn 3x-2y=14 into slope equation which would be y=3/2x-7 and. Since it's a parallel line u only need to change the y intercept do if u put it on a graph, the equation would be y=3/2x-2 bc it goes through the point (-6,-11) and is also parallel to the standard equation given.

A system of equations is shown below:y = 8x − 2
y = 9x − 7

What is the solution to the system of equations?

(−5, 38)
(−5, −38)
(5, 38)
(5, −38)

Answers

y = 8x - 2
y = 9x - 7

8x - 2 = 9x - 7
- 8x - 8x
-2 = x - 7
+ 7 + 7
5 = x

y = 8x -2
y = 8(5) - 2
y = 40 - 2
y = 38
(x, y) = (5, 38)

The answer is C.

Answer would be C (5, 38)
