Answer:

We conclude that:

\frac{18p}{5}+12q+18-\frac{18p}{5}-16q-6=-4q+12

Hence, option A is true.                    

Step-by-step explanation:

Given the expression

3\left(\frac{6}{5}p+4q+6\right)-2\left(\frac{9}{5}p+8q+3\right)

solving the expression

3\left(\frac{6}{5}p\:+\:4q\:+\:6\right)\:-\:2\left(\frac{9}{5}p\:+\:8q\:+\:3\right)=3\left(\frac{6p}{5}+4q+6\right)-2\left(\frac{9p}{5}+8q+3\right)

Expand  3\left(\frac{6p}{5}+4q+6\right)=\frac{18p}{5}+12q+18

                                                           =\frac{18p}{5}+12q+18-2\left(\frac{9p}{5}+8q+3\right)

Expand  -2\left(\frac{9p}{5}+8q+3\right)=-\frac{18p}{5}-16q-6

                                                             =\frac{18p}{5}+12q+18-\frac{18p}{5}-16q-6

Group like terms:                                

                                                             =\frac{18p}{5}-\frac{18p}{5}+12q-16q+18-6

Add similar elements: \frac{18p}{5}-\frac{18p}{5}=0

                                                               =12q-16q+18-6

Add similar elements:  12q-16q=-4q

                                                                =-4q+18-6

                                                                =-4q+12

Therefore, we conclude that:

\frac{18p}{5}+12q+18-\frac{18p}{5}-16q-6=-4q+12

Hence, option A is true.

Determine all possibilities for the solution set of a system of 2 equations in 2 unknowns. I. No solutions whatsoever. II. One a
Minchanka [31]

Answer:

II. One and only one solution

Step-by-step explanation:

Determine all possibilities for the solution set of a system of 2 equations in 2 unknowns. I. No solutions whatsoever. II. One and only one solution. III. Many solutions.

Let assume the equation is given as;

x + 3y = 11 .... 1

x - y = -1 ....2

Using elimination method

Subtract equation 1 from 2

(x-x) + 3y-y = 11-(-1)

0+2y = 11+1

2y = 12

y = 12/2

y = 6

Substitute y = 6 into equation 2:

x-y = -1

x - 6 = -1

x = -1 + 6

x = 5

Hence the solution (x, y) is (5, 6)

<em>Hence we can say the equation has One and only one solution since we have just a value for x and y</em>

Can Someone Help Please.
djverab [1.8K]

Answer:

1. y = 9280 - 20x

2. f(y) = 6.37y - 3

Step-by-step explanation:

1. The equation is given to be \frac{1}{16}x + \frac{1}{320}y - 29 = 0

Now, rearranging the function we can write  

\frac{y}{320} = 29 - \frac{x}{16}

⇒ y = 9280 - 20x

Hence, this is the equation as a function of x. (Answer)

2. The given function is y - 6.37x = - 3

Therefore, we can write, y = 6.37x - 3

Hence, f(x) = 6.37x - 3

⇒ f(y) = 6.37y - 3.

Hence, option D is true. (Answer)

How do I find the endpoint of a segment when given the first endpoint (-6, 5) and the midpoint(-1.5, 1)?​
Anika [276]

Answer:

(3, -3)

Step-by-step explanation:

Use the midpoint formula.

x = (x₁ + x₂) / 2

-1.5 = (-6 + x) / 2

-3 = -6 + x

x = 3

y = (y₁ + y₂) / 2

1 = (5 + y) / 2

2 = 5 + y

y = -3

The other endpoint is (3, -3).
