To find the solution, we use the substitution method.
x+y=-1
<span>x-3y=11
</span>
x+y = -1-y
-y
x = -1-y
Now apply the value of x into the other equation.
x-3y=11
-1-y-3y = 11
Combine like terms
-4y -1 = 11
+1 +1
-4y = 12
-4y = 12
-4y/-4 = 12/-4
y = -3
Now, apply the value of Y to one equation to find x.
y = -3
x -3 = -1
+3 +3
x= 2
Now we have the value for both, x and y.
x = 2
y =-3
Final answer: A. <span>(2, −3)</span>
The opening balance of the March billing cycle for Bernice's credit card = $2374.
Amount of new purchase = $200 on the 20th of March.
She did purchase only of $200 in that March month.
We are given that she didn't do any payment.
So, still she has balance $2374 till end of the month.
Therefore, her average daily balance is $2374.00
So, the correct option is B. $2374.00.
Y= 12 because anything to the 0 power is 1 so 4*1=4 * 3=12
There's not enough info to know the exact number for each. There would be at least a 2 different answers because either could be calculated to conclude the end result.
Answer: C (A unimodal histogram, and the dotted line lands at 210)
Step-by-step explanation:
Khan Academy - “The sample size is reasonably large (n = 30 _> 30), so the sampling distribution of x will be approximately normal even though the population isn’t.”
