Answer:
n = -8
Step-by-step explanation:
Given the expression
(-2y-3) + (-6y-5) = (ny -8),
Expanding the LHS
-2y-3 - 6y -5 = ny - 8
-2y-6y-3-5 = ny - 8
-8y - 8 = ny - 8
Compare both sides
-8y = ny
-8 = n
Swap
n = -8
Hence the value of n is -8
Answer:
(-4, -5)
Step-by-step explanation:
-4x + 2y = 6
-4x + 2(x - 1) = 6
-4x + 2x - 2 = 6
-2x - 2 = 6
-2x - 2 + 2 = 6 + 2
-2x = 8
-2x/-2 = 8/-2
x = -4
------------------------
y = x - 1
y = -4 - 1
y = -5
-------------------------
-4(-4) + 2(-5) = 6
16 + -10 = 6
6 = 6
it would be 2/6 bc, one die, rolled twice, and landing on a 2 the first time and 6 the second time, is actually a 2/6 chance, you have 6 numbers, one die, two chances.
