what is 2x - y = -42
Answer:
A linear equation
Step-by-step explanation:
It just is
Answer:
Step-by-step explanation:
2x + -1y = -42
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add 'y' to each side of the equation.
2x + -1y + y = -42 + y
Combine like terms: -1y + y = 0
2x + 0 = -42 + y
2x = -42 + y
Divide each side by '2'.
x = -21 + 0.5y
Simplifying
x = -21 + 0.5y

Jordan uses 1/4 of the 31/2 yards of fabric she has to make a top. How many yards did she use?
The fabric left is 2 1/4 yards which is calculated using subtraction.
Total fabric = 3 1/2 = 7 / 2 yards
Used fabric = 1 / 4 yards
Fabric left will be calculated using subtraction.
So, we get that:
Left fabric = 7 / 2 - 1 / 4
= 14 / 4 - 1 / 4
= 13 / 4
= 2 1/4 yards.
Therefore, we get that, the fabric left is 2 1/4 yards which is calculated using subtraction.

Answer:
Step-by-step explanation:
75x + -300 = 25x + 200
Reorder the terms:
-300 + 75x = 25x + 200
Reorder the terms:
-300 + 75x = 200 + 25x
Solving
-300 + 75x = 200 + 25x
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-25x' to each side of the equation.
-300 + 75x + -25x = 200 + 25x + -25x
Combine like terms: 75x + -25x = 50x
-300 + 50x = 200 + 25x + -25x
Combine like terms: 25x + -25x = 0
-300 + 50x = 200 + 0
-300 + 50x = 200
Add '300' to each side of the equation.
-300 + 300 + 50x = 200 + 300
Combine like terms: -300 + 300 = 0
0 + 50x = 200 + 300
50x = 200 + 300
Combine like terms: 200 + 300 = 500
50x = 500
Divide each side by '50'.
x = 10

(pre-calc) Use Limit Laws to determine the limit of a(n). It is not -∞, so what answer is it and why?
The limit of the function as the variable n tends to minus infinity is -1
Limit of a functionGiven the limit of a function expressed according to the equation;
a(n) = 6n²-n-3n³/3n³+n-1
The value of the function if n tends to minus infinity is expressed as show:
a(n) = 6n²-n-3n³/3n³+n-1
Divide both all the terms by n³
a(n) = 6n²/n³-n/n³-3n³/n³/3n³/n³+n/n³-1/n³
a(n) = 6/n-1/n²-3/(3+1/n²-1/n³)
a(n) = 6/-∞ - 1/(-∞)²-3/(3+1/(-∞)²-1/(-∞)³)
a(n) = -3/3

In uniform probability distributions, the likelihood of each possible outcome happening or not is the same. This property means that, for any given trial, the probability that an event will be successful does not change. Take the probability of rolling a 5 on a die for instance, no matter how many trials are performed, there is always a 1 in 6 probability for each trial.
