Hello!
For the given problem the inequality will be;

x+4<or equal to 13

this is saying any number (x) plus 4 is equal to or less than 13 and this follows the question of 4 more than a number(x) is no more than 13. So it is saying the sum of these two number can equal or be less than 13.

Hope this helps! Any questions please just ask! Thank you so much!

The function g is defined by g(x) = 3x - 5.<br> Find g (2x).
Lady bird [3.3K]
We want to replace x with 2x in the original equation
g(2x) = 3(2x) -5
We can multiply 3 and 2x to simplify this, which will give us 6x
g(2x) = 6x - 5

A concession stand at an athletic event is trying to determine how much to sell cola and iced tea for in order to maximize reven
Cerrena [4.2K]

Solution :

Demand for cola : 100 – 34x + 5y

Demand for cola : 50 + 3x – 16y

Therefore, total revenue :

x(100 – 34x + 5y) + y(50 + 3x – 16y)

R(x,y)  = $100x-34x^2+5xy+50y+3xy-16y^2$

$R(x,y) = 100x-34x^2+8xy+50y-16y^2$

In order to maximize the revenue, set

$R_x=0, \ \ \ R_y=0$

$R_x=\frac{dR }{dx} = 100-68x+8y$

$R_x=0$

$68x-8y=100$  .............(i)

$R_y=\frac{dR }{dx} = 50-32x+8y$

$R_y=0$

$8x-32y=-50$  .............(ii)

Solving (i) and (ii),

4 x (i)    ⇒       272x - 32y = 400

     (ii)   ⇒   (-<u>)     8x - 32y = -50   </u>

                        264x        = 450

∴   $x=\frac{450}{264}=\frac{75}{44}$

     $y=\frac{175}{88}$

So, x ≈  $ 1.70      and    y = $ 1.99

    R(1.70, 1.99) = $ 134.94

Thus, 1.70 dollars per cola

          1.99 dollars per iced ted to maximize the revenue.

Maximum revenue = $ 134.94

One third of a bird's eggs hatched. If 2 eggs hatched, how many eggs did the bird lay?
Elodia [21]
The bird laid 6 eggs since only 1/3 hatched, one can multiply 2 by 3 to get 3/3 of the eggs which would equal 6.
