Step-by-step explanation:
-4x - 2y = 18
+ (4x - 4y = -36)
=> -6y = -18, y = 3
As we added the equations together, we have eliminated x and found y.
Hence the correct answer is "Add to eliminate x".
Answer:
$295.01
Step-by-step explanation:
Using the compounding continuously formula, we are looking for A. We have that P = 190; r = .11 (always use the decimal form of the rate!); and t = 4. Filling in we have:
Simplifying that multiplication:
.
On your calculator, raise e to the .44 power to get
A = 190(1.552707219) and
A = $295.01
Answer:
B
Step-by-step explanation:
Answer:
P₂ =
Step-by-step explanation:
Given expression:
Boyle's law:
P₁ V₁ = P₂ V₂
Problem is to find P₂;
Solution:
P₁ V₁ = P₂ V₂
To solve this problem, multiply both sides by ;
P₁ V₁ x ; = P₂ V₂ x ;
cancels out V₂ on the right hand side;
P₂ =
