How many solutions does the system of equations below have?<br><br> x − 4y = 6<br> 2x − 8y = 12
bearhunter [10]

Answer:

x = 4y + 6

Step-by-step explanation:

x-4y=6

2x-8y=12

multiply 2 on both side in equation 1, and multiple - on both side in equation 2:

2x-4x=12

-2x+8y=-12

so the equation becomes:

4y=0

y=0

put the value of y in both of the equations:

x=6 equation 1

x=6 equation 2

so,

x = x

then,

x = 4y + 6 equation 1

-2 ( x - 4y ) = -12

x - 4y = -12/ -2

x - 4y = 6

x = 4y + 6

so the ans is:

x = 4y +6

The least common multiple of a number n and 6 is 42 what are all of the possible whole number values for n
iren [92.7K]
I did it with "tries & mistakes" method:

n is not 1, because LCM of 1 and 6 is 6
n is not 2, because LCM of 2 and 6 is 6
n is not 3, because LCM of 3 and 6 is 6
n is not 4, because LCM of 4 and 6 is 12
n is not 5, because LCM of 5 and 6 is 30
n is not 6, because LCM of 6 and 6 is 6
n might be <u>7</u>, because LCM of 7 and 6 is what we're looking for - 42.
n might be also <u>14</u> or <u>21</u> - so these are all multiplies of 7 which are less or equal to half of 42.

I hope it helps :)

Graph the function y = |1.6x – 2| – 3.2. Over which interval is the function increasing?
Murrr4er [49]
Hmm,
the absolute value makes whaterver inside positive
so

find whre the abslte value is 0
1.6x-2=0
1.6x=2
x=2/1.6
x=1.25

as x approaches 1.25, the function decreases

so from left to right
from the left to right, from -ifninty to 1.25, it is decreasing
from 1.25 to infinity, it is increasing

so it is increasing in the interval (1.25,∞)
