3v=v+6

Subtract v from both sides

3v-v = v+6-v

2v= 6

Now divide both sides by 2

2v/2=6/2

v= 3


I hope that's help:0


Lets check if the answer is good

all you need to do is to replace v by 3

3v=v+6

3(3)=3+6

9=9

The answer is good

Irina18 [472]

Answer:

the graph will describe 13x+15 if the cost per audio book goes up by $1.00.

Step-by-step explanation:

This happens because the coefficient to x is 12 before the change. If the change is the cost per audio book going up by one dollar, the coefficient changes to 13. The initial joining fee is the same ($15.00).

What is the value of (2x^2-5x+4)if x =7
Troyanec [42]
<span>We have to use PEMDAS for this expression.

Parentheses
Exponents
Multiplication
Division
Addition
Subtraction

</span>(2x^2 - 5x + 4)                    Original Mathematical Expression

[2(7)^2 - 5(7) + 4]                 Plugging the value of x, 7 into expression.

There are parentheses, so that means we have to work in them.

There are exponents, so we have to do those first.

[2(49) - 5(7) +4]                    Exponents.

There is multiplication, that we can do, so we do that left to right.

[98 - 35 + 4]                         Multiplication.

There is no division.

There is addition and subtraction, so we do those left to right.

[63 + 4]                                Subtraction.

67                                        Addition.

Final Answer: 67
