A local coffee shop sells 35 medium and large cups

Orlov [11]

The right answer is Option C: 20

Step-by-step explanation:

Given,

Cost of medium cup of coffee = $3.00

Cost of large cup of coffee = $4.00

Total cups sold = 35

Total revenue for the coffee = $125.00

Let,

Number of medium cups of coffee = x

Number of large cups of coffee = y

According to given statement;

x+y=35 Eqn 1

3.00x+4.00y=125.00 Eqn 2

Multiplying Eqn 1 by 3;

$3(x+y=35)\\3x+3y=105\ \ \ Eqn\ 3$

Subtracting Eqn 3 from Eqn 2

$(3.00x+4.00y)-(3x+3y)=125.00-105\\3.00x+4.00y-3x-3y=20\\y=20$

As y represents the number of large cups, therefore,

20 large cups of coffee were sold by the shop.

The right answer is Option C: 20

I don't know what to do. This is about odd and even functions.

Alexxandr [17]

Answer:

Step-by-step explanation:

We are given $f,g$ are odd which means:

$f(-x)=-f(x)$

$g(-x)=-g(x)$

We can tell if a function, $h$ , is even if $h(-x)=h(x)$ .

We can tell if a function, $h$ , is odd if $h(-x)=-h(x)$ .

So let's test your I,II,III.

We will be replacing x with -x to find out.

$p(x)=f(g(x))$

$p(-x)=f(g(-x))$

$p(-x)=f(-g(x))$

$p(-x)=-f(g(x))$

$p(-x)=-p(x)$

So $p$ is odd.

$r(x)=f(x)+g(x)$

$r(-x)=f(-x)+g(-x)$

$r(-x)=-f(x)+-g(x)$

$r(-x)=-(f(x)+g(x))$

$r(-x)=-(r(x))$

$r(-x)=-r(x)$

So $r$ is odd.

III

$s(x)=f(x)\cdot g(x)$

$s(-x)=f(-x) \cdot g(-x)$

$s(-x)=-f(x) \cdot -g(x)$

$s(-x)=f(x) \cdot g(x)$

$s(-x)=s(x)$

So $s$ is even.

So I and II are odd and III is even.

C. is the answer.
