Short answer-
5 ways.

Explanation-
This is a *little* hard to explain through text but hopefully this should be fine.

So, in the image below we have 7 audience members (orange) including you and your buddy (green).
In the columns I have marked how many times you, your friend and another audience member has been theoretically chosen.

As we can see, both you and your friend have been chosen five times, while everyone else has been chosen once.
These are all the possible combinations.
The answer is 5.
Hope this helps :)

Answer:

f(-3) = g(-3)

Step-by-step explanation:

Let's look at each option to which one is true with regard to the given functions on the graph.

The option that is correct is the option that shows where the graph of f(x) and g(x) intercepts or cut across each other.

Now, take a look at the graph, the line of both functions intercepts at x = -3. At this point, the value of f(-3) and g(-3) is equal to -4.

Therefore: f(-3) = g(-3)

The difference of two positive numbers is 69. The quotient obtained on dividing one by the other is 4. Find the number.

valentinak56 [21]

Answer:

x=92 y=23

Step-by-step explanation:

Let them be x and y respectively

so given

x-y=69

and

x/y=4 x=4y

so we can write

x-y=69

as

4y-y=69 3y=69 y= 69/3 = 23

now y is 23

so putting in any equation will give the value of x

so

x-23=69 x=92

There are six wires which need to be attached to a circuit board. A robotic device will attach the wires. The wires can be attac

lesya692 [45]

Answer:

$S=720$

Step-by-step explanation:

From the question we are told that

Six wire are attached to a circuit board

Generally using multiplication rule

Let number of possible sequence be given as S

Mathematically

$S=6! =6*5*4*3*2*1=720$

Therefore

Number of possible sequence $S=720$

Hey i need help with system of equations.<br> i uploaded a doxs file you can onpen it in google docs

Art [367]

Answer:

<h2>PART A: x = 15 and y = -8</h2><h2>PART B: x = -5 and y = 3</h2>

Step-by-step explanation:

PART A:

The first equation is $x + y = 7\\y = 7 - x .............(a)$

The second equation is $3x - 2y = 1\\2y = 3x - 1$

Putting the value of y from (a) in the above equation, we get $2y = 3x - 1\\2(7 - x) = 3x - 1\\14 - 2x = 3x - 1\\x = 15$

From (a) we get y = 7 - x = 7 - 15 = -8

PART B:

Here the system of equations are $-x + 4y = 17........(a) and 3x - 5y = -30.........(b)$

From (a) we get, $x = 4y - 17$

Putting the above value of x in (b) we get, $3x - 5y = -30\\3(4y - 17) - 5y = -30\\12y - 51 - 5y = -30\\7y = 21\\y = 3$

Hence, $x = 4y - 17 = 12 - 17 = -5$
