y = 8x + 12
3.x – 3y = 6
Step-by-step explanation:
y = 8x + 12 _____(1)
3x - 3y = 6 ______(2)
Substituting the.the expression for y in eqn (1)
into eqn (2).
3x - 3(8x + 12) = 6
3x - 24x - 36 = 6
-21x = 42
x = -2.
y = 8(-2) + 12 = -4.
hence x = -2 and y = -4.
Answer:
54
Step-by-step explanation:
To obtain a mixture that is 70% antifreeze, you need to mix 70 gallons of an 80% antifreeze solution with 70 gallons of a 30% antifreeze solution.
To determine how many gallons of an 80% antifreeze solution must be mixed with 70 gallons of 30% antifreeze to get a mixture that is 70% antifreeze, we can use the concept of the concentration of solutions.
Let's assume x gallons of the 80% antifreeze solution need to be added.
The amount of antifreeze in the 80% solution is 0.8x gallons, and the amount of antifreeze in the 30% solution is 0.3 * 70 = 21 gallons. The total amount of antifreeze in the final mixture is 0.7 * (70 + x) gallons.
Setting up the equation: 0.8x + 21 = 0.7 * (70 + x).
Solving for x, we get x = 70 gallons. Therefore, you need to mix 70 gallons of the 80% antifreeze solution with 70 gallons of the 30% antifreeze solution to get a mixture that is 70% antifreeze.

Answer:
Var(X)=1.6
Step-by-step explanation:
Formula for calculating the coefficient of variation for a probability generating function:
Var(X)= PX''(1) + PX'(1) - [PX'(1)]² ........... eq(1)
Now compute each individual term in the above formula.
PX'(z) =
PX'(1) = = 8
[PX'(1)]² = 64
PX''(z) =
PX''(1) = = 57.6
Substitute all terms back in eq(1)
Var(X)= 57.6 + 8 - 64
Var(X)= 1.6
