I hope this helps you
y=5x+6 this lines slope= -5
-3 (6x-y)= -54
6x-y= 18
y= 6x-18 this lines slope= -6
parallel lines slopes equal
-5 is not equal -6 not parallel

Answer:
x = - 5
Step-by-step explanation:
Given
f(x) = - 4x - 10 and f(x) = 10, the equate right sides, that is
- 4x - 10 = 10 ( add 10 to both sides )
- 4x = 20 ( divide both sides by - 4 )
x = - 5
Answer:
z-score = 1
Step-by-step explanation:
Given
Mean= μ=240
SD= σ=32
In order to find the z-score of a value, the mean is subtracted from the value and then divided by standard deviation.
The formula for z-score is:
z-score=(x-μ)/σ
Here x is the value whose z-score is to be found.
In the given question, x = 272
So,
z-score=(272-240)/32
=32/32
=1
So , the z-score for 272 is 1..
