Answer:

v = -16

Step-by-step explanation:

<u>→Distribute the 5 to (-7v - 11):</u>

14 - 10v + 11 = 20v - 35v - 55

<u>→Add like terms:</u>

25 - 10v = -15v - 55

<u>→Add 15v to both sides:</u>

25 + 5v = -55

<u>→Subtract 25 from both sides:</u>

5v = -80

<u>→Divide both sides by 5:</u>

v = -16

Answer:

\boxed{v =  - 16}

Step-by-step explanation:

=  > 14 - 10v + 11 = 20v + 5( - 7v - 11) \\  \\  =  > 14  + 11 - 10v = 20v + (5 \times ( - 7v)) - (5 \times 11) \\  \\  =  > 25 - 10v = 20v - 35v - 55 \\  \\  =  > 25 - 10v =  - 15v - 55 \\  \\  =  > 25  - 10v + 15v =  - 55 \\  \\  =  > 25  + 5v =  - 55 \\  \\  =  > 5v =  - 55 - 25 \\  \\  =  > 5v =  - 80 \\  \\  =  > v =  -  \frac{80}{5}  \\  \\  =  > v =  - 16

Which of the following coordinate pairs make the equation x - 9y = 12 true?
Ne4ueva [31]

Options:

(12,0)     (0,12)    (3,-1)    (0,-4/3)

Answer:

(12,0) ,  (3,-1)  and (0,-4/3)

Step-by-step explanation:

Given

x - 9y = 12

Required

Which option is true?

A coordinate point is of the form; (x,y)

So, we have to substitute the x and y values in the given equation.

A. For (12,0)

x = 12 and y = 0

x - 9y = 12 becomes

12 - 9*0 = 12

12 - 0 = 12

12 = 12

<em>This is true</em>

B. For (0,12)

x = 0 and y = 12

x - 9y = 12 becomes

0 - 9*12 = 12

- 9*12 = 12

- 108 = 12

<em>This is false</em>

C. For (3,-1)

x =3 and y = -1

x - 9y = 12 becomes

3 - 9*-1 =12

3 + 9 =12

12 = 12<em></em>

<em></em>

<em>This is true</em>

D. For (0,-4/3)

x = 0 and y = -\frac{4}{3}

x - 9y = 12 becomes

0- 9*-\frac{4}{3} = 12

0+ 9*\frac{4}{3} = 12

0+ 3*4 = 12

0+12 = 12

12 = 12

<em></em>

<em>This is true</em>

<em></em>

<em>Hence, (12,0) ,  (3,-1)  and (0,-4/3) are true values of the equation</em>
