American Airlines charges $270 for a flight to Denver and $50 for each piece of luggage. Delta Airlines charges $330 for a flight and only $30 for each piece of luggage. Which inequality shows the number of pieces of luggage that need to be checked for American Airlines to cost more than Delta Airines for a flight to Denver?
F 270 + 50x > 330 + 30x
G 270x +50 > 330x + 30
H 270x + 50 < 330x +30
J 270 +50x > 330 + 30x
Answer:
J; 250 + 50x > 330 + 30x
Step-by-step explanation:
Since we don't have to worry about formatting the numbers to slope-intercept form, we can start the process of elimination.
First, we can disregard G and H because both have the x in the wrong place:
—> F 270 + 50x ≥ 330 + 30x
—> G 270x + 50 > 330x + 30
—> H 270x + 50 < 330x +30
—> J 270 + 50x > 330 + 30x
We're looking for 270 + 50x > 330 + 30x.
Next, we determine which symbols are correct. Since the question is only asking for when American Airlines would be more expensive, not when it would be just as much or more, we can get rid of F.
—> F 270 + 50x ≥ 330 + 30x
—> J 270 +50x > 330 + 30x
We finally have our answer, J.

(dy/dx) - 2xy = x, y(0) = 0, find y(1).
Answer :
2y=1+e−x2
Solution :
IF=e∫2xdx=ex2
∴y×ex2=∫xex2dx=12∫etdt+C, where x2=t
=12ex2+C.
∴y=12+Cex2
Putting y=1andx=0, we get C=12.
help plz with question
Answer:
y = -x +1
Step-by-step explanation:
-0+1 = 1
-(-6)+1 = 7
etc
Answer:
y = - x + 1
Step-by-step explanation:
m = [tex]\frac{y_{2} -y_{1} }{x_{2} -x_{1} }[/tex]
y - [tex]y_{1}[/tex] = m( x - [tex]x_{2}[/tex] ) point - slope form
y = mx + b slope - intercept form
~~~~~~~~~~~~
(1, 0)
(3, - 2)
m = ( - 2 - 0 ) / ( 3 - 1 ) = - 1
y - 0 = ( - 1)(x - 1)
y = - x + 1
julie opens a bank account with $500.she deposits $60 each month.write a function that represents the amount that is in julies account after x months
Answer:
[tex]f(x) = 500 + 60x[/tex]
Step-by-step explanation:
Given
[tex]Ope\ ning\ Balance = 500[/tex]
[tex]Deposits = 60[/tex] --- monthly
Required
Write as a function
Represent the number of months with x and the balance at any month with f(x)
f(x) is calculated as thus:
Opening Balance + Deposits * Number of Months
So, we have:
[tex]f(x) = 500 + 60 * x[/tex]
[tex]f(x) = 500 + 60x[/tex]
Hence, the function that represents the scenario is
[tex]f(x) = 500 + 60x[/tex]

An equilateral triangle has sides of equal length. Find the dimensions of an equilateral triangle with a perimeter of 45 inches. P=4s
Answer:
P= 4s
P= 4(45)
P= 180 in.
Explanation: write down the formula first. Then write down P= 4s, but change the "s" to the 45. Then multiply 45 by 4 then you have your answer. If your teacher ask you for an degrees it will be 180°. Which is also the sum of a triangle.

(0,3)
(3,2)
(4,0)
Step-by-step explanation:
The feasible region is the doubly-shaded area in the lower left corner of the first quadrant. It is a quadrilateral, so has 4 vertices. Those are the vertices of the feasible region:
(0,0)
(0,3)
(3,2)
(4,0)

Step-by-step explanation:
8(-8x – 6) = -6x - 22
solve for x
Answer:
x = - 13/29 OR x = - -0.44827586
Step-by-step explanation:
We use PEMDAS to evaluate the equation.
P stands for parenthesis. In this case we distribute the 8 to the equation in parenthesis.
8(-8x - 6)
-64x - 48 = -6x - 22 we will move the terms to their proportional sides
-64x + 6x = 22 + 48 (remember we do the opposite equation to move to the other side of the equals to sign)
-58x = 70 we divide both sides by -58 to isolate x
x = - 13/29 OR x = - -0.44827586
