Solve the system of equations. y = 6x - 27 y = 4x - 17
NeTakaya
Y=6x-27...........(1)
y=4x-17...........(2)

By comparison
6x-27=4x-17
=> 2x=10 => x=5
Substitute x=5 into (1)
y=6(5)-27=3
Check:
y=4(5)-17=3 as well.

Answer the picture below.
pav-90 [236]

Answer:

The distance between point M and point L is 8

Step-by-step explanation:

The given points on the coordinate are M = (- 2, 4) and L = (4, - 1)

The formula for determining the distance between two points is expressed as

d = √(x2 - x1)^2 + (y2 - y1)^2

Where

y2 = final value of y = - 1

y1 = initial value of y = 4

x2 = final value of x = 4

x1 = initial value of x = - 2

Therefore,

d = √(4 - - 2)^2 + (- 1 - 4)^2

d = √6^2 + (-5)^2

d = √36 + 25

d = √61 = 8
