Answer:

x = \frac{A}{4y}

Step-by-step explanation:

Given

A = 4xy ( isolate x by dividing both sides by 4y )

\frac{A}{4y} = x

Find all solutions to the following system of equations -y²+6y+x-9=0 ; 6y=x+27.Illustrate with a graph.
Dimas [21]

Answer:

The solution to the system is the pair (9, 6)

Step-by-step explanation:

Hi!

First, let´s write the system of equations:

-y² + 6y + x -9 = 0

6y = x +27

The solutions of the system are the pairs (x, y) that satisfy both equations.

Let´s take the second equation and solve it for x:

6y = x +27

Subtract 27 from both sides of the equation

6y - 27 = x

Now, we can replace x in the first equation and solve it for y:

-y² + 6y + x -9 = 0

-y² + 6y + 6y - 27 -9 = 0

-y² + 12y - 36 = 0

Notice that -y² + 12y - 36 = -(y - 6)², then:

-(y - 6)² = 0

y - 6 = 0

y = 6

(alternatively you can solve the quadratic equation using the quadratic formula).

Now let´s find the value of x:

x = 6y -27

x = 6·6 -27

x = 9

The solution to the system is the pair (9, 6)

Please see the attached figure. The point where the curves intersect is the solution to the system.

A club has 800 members. 100 of the members were randomly picked and were asked if the dues should be raised. 6 of the members sa
frez [133]

Answer:

About 48 members would be expected to say that dues be raised

Step-by-step explanation:

Here, we shall be using a case of a representative sampling to determine the actual.

Out of the 100 selected members, 6 said the dues should be raised;

This represents a percentage of 6/100 = 6%

So out of the 800, the expected number of members that would ask for a dues raising will be;

6/100 * 800 = 48

BRAILEST + THANKS <br> F(x)=x^2+14 and g(x)=x−8<br> Find (f+g)(−1)
Murrr4er [49]

Answer:

Step-by-step explanation:

Disclaimer all solutions need to be verified by the student for accuracy in typos, algebra and calculations.

f(x) = x² + 14      g(x) = x - 2      -1 ?   I think it means evaluate when x = -1

Find (f(x) + g(x))  when x = -1

 (f(x) + g(x))  =   [ ( x² + 14)  +  (x - 2)]        insert f(x)  and g(x)

                    =   [ x² + x + 14 - 2]               add like the term

 (f(x) + g(x))  =   x² + x + 12

(f(-1) + g(-1))  =   (-1)² + (-1) + 12             evaluate at x = -1

                   =    1 - 1 + 12

                   =    12
