First fine the slope.
How?
2 random points and plug them in the slope formula.
In this case :
(-3,0)(0,4) —> 4-0/0-(-3) = 4/3 <— slope
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)
y = 4/3x + 4
Hope I helped:)

♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️

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

[tex]y = {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]

[tex]x≠ - \sqrt{y - 5} [/tex]

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

So ;

The larger of two numbers is sixteen less than twice the smaller number. If the sum of the numbers is 44, find the two numbers. Write your answer as two numbers separated by a coma.

Answers

Answer:

20, 24

Step-by-step explanation:

smaller:   x

  larger:  2x - 16

x + 2x - 16 = 44

3x -16 = 44

3x = 60

x = 20

smaller:   x = 20

  larger:  2x - 16 = 2(20) - 16 = 24

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 = 39

Step-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 Multiply

13x = 117

Step 2: Divide both sides by 13

13x / 13 = 117 / 13

x = 9

Step 3: Check

3 / 13 = 9 / 39

117 = 117 ✅

x = 9 when y = 39

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

3. Lim
x-infinity

x²+3
[AP]

Answers

Answer:  0

=======================================================

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.
