Answer:
-6
Step-by-step explanation:
We are given x=- 3 , y= 6 and z= -4.
We are also given the expression:
-15 + (-x) +y
Substitute -3 in for x and 6 in for y.
-15 + (- -3) + 6
2 negative signs creates a positive sign
-15 + (+3) +6
-15 + 3+ 6
Add -15 and 3.
(-15+3) +6
-12 +6
Add -12 and 6.
-6
-15+(-x)+y evaluated at x= -3 and y=6 is equal to -6.

Neither because sometimes as x increases, y increases and sometimes as x increases, y decreases so this graph have no corrleation so it neither.
Answer:
7 ( 2x + 3y - z)
Step-by-step explanation:
To factor this expression, you need to find the GCF, which is 7.
7 ( 2x + 3y - z)
