1.)  4=-6v+5v combine like terms -6v=5v=-1v rewrite 4=-1v divide -1 from both sides 4/-1=-4 rewrite v=-4

2.)  -7(3r+6)=7(7r+4) we r goin to have to distribute -7(3r)=-21r   -7(6)= -42 same for the other side   7(7r)=49r  7(4)=28 rewrite 
-21r-42=49r+28 add 42 to both sides 28+42=66 rewrite -21r=49r+66 subtract 49r from both sides -21r-49r=-70r rewrite -70r=66 divide -70 from both sides 66/-70=-0.94  r=-0.94
hope this helps have a nice nite

If y varies inversely as x and y=7 when x=−4, find y when x=2.
olga2289 [7]

Answer:

Explanation:

The statement is expressed as

y

∝

1

x

inverse means

1

variable

To convert to an equation introduce k, the constant of variation.

y

=

k

×

1

x

⇒

y

=

k

x

To find k use the given condition that y = 8 when x = 4

8

=

k

4

⇒

k

=

4

Two numbers multiply to be -7 and add to be -6. What are the numbers?<br><br> Example; 2,3
rewona [7]

<u>Given</u>:

Let the two numbers be x and y.

Two numbers multiply to be -7 and add to be -6.

This can be written in equation as,

xy=-7 and

x+y=-6

<u>Value of the two numbers:</u>

Let us determine the value of the two numbers using substitution method.

Substituting y=-6-x in the equation xy=-7, we get;

x(-6-x)=-7

Simplifying, we get;

       -6x-x^2=-7

   x^2+6x-7=0

(x+7)(x-1)=0

x=-7, 1

Thus, the values of x are x = 1,-7

When x = 1 , the equation x+y=-6 becomes y=-7

When x = -7, the equation x+y=-6 becomes y=1

Therefore, the two numbers are 1 and -7
