The value of y varies directly with x. If x = 3, then y = 13. Show your work for finding the value of x when y = 39
Answers
Answer:
x = 9 when y = 39Step-by-step explanation:
To solve this, we will use a proportion, since x varies directly with y, each will increase proportionately to the other.
3 / 13 = x / 39
Step 1: Cross Multiply13x = 117
Step 2: Divide both sides by 1313x / 13 = 117 / 13
x = 9
Step 3: Check3 / 13 = 9 / 39
117 = 117 ✅

Audrey's bank account is currently at $75 a fee of 12.50 is deducted each month from Audreys she must maintain a balance greater than zero dollars how many months will Audrey's account stay above zero dollars
Answers
Answer:
5 months
Step-by-step explanation:
Current balance = $75
Monthly deductions = $12.50
75 - 12.5h
Where ,
h = number of months for deduction
she must maintain a balance greater than zero dollars
how many months will Audrey's account stay above zero dollars
0 > 75 - 12.5h
0 - 75 > -12.5h
-75 > - 12.5h
h < -75 / 12.5h
h < 6 months
h < 6 months means h must be less than 6 months which is 5 months
Audrey's account will stay above zero dollars for 5 months and will equal zero dollars in the 6th month

[tex]f(x) = {x}^{2} + 5[/tex]

[tex] {x}^{2} + 5 = y[/tex]
Subtract sides 5
[tex] {x}^{2} + 5 - 5 = y - 5[/tex]
[tex] {x}^{2} = y - 5[/tex]
[tex]x = ± \sqrt{y - 5} [/tex]

Because x is a positive number but -√y-5 is a negative number thus it's unacceptable.

The y intercept is the point where x equals 0
In this case :
(0,4) —> 4 is the y-Intercept
Now, plug in for the equation y= mx + b ( m = slope and b = y intercept)

[AP]
Answers
=======================================================
Explanation:
Let n be the degree of the numerator
Let d be the degree of the denominator
If n < d, then the limit at infinity is always 0. This is because the denominator is growing faster compared to the numerator. I suggest looking at a table of values to see this in action.
In this case, n = 3 and d = 4, so we see that n < d is the case here. So that's why the answer is 0.
----------------------
Side notes:
If n = d, then the limit at infinity is equal to a/b, where a and b are the leading terms of the numerator and denominator. If n > d, then the numerator is growing faster than the denominator, meaning the ultimate result is infinity.
