Answer:
(-1, -8)
Step-by-step explanation:
So you would do the simplifying by "subtracting" the equations from each other. So to isolate the x, you could subtract the y away.
8x + y = -16
-3x + y = -5
-___________
11x = -11
x = -1
Then, substitute x into either equation.
8(-1) + y = -16
-8 + y = -16
Isolate y.
y = -8
D) 800 because you can’t get 400 if you didn’t flip the coin over 400 times.. this is because the coin has a 50/50 chance of heads or tails so you double the expectation

Answer:
The least whole number is the number 1
Step-by-step explanation:
we have
Remember that
<u>Whole numbers</u> are positive numbers, including zero, without any decimal or fractional parts [0,1,2,3,4,5,6,...]
so
Solve the inequality for x
Divide both sides by 400
Rewrite
therefore
The least whole number is the number 1
