 Assuming you want to know the value of "v" 

So, step one we would have solve from the same value 

\frac{1}{12}(12-v) =  \frac{1}{6}(v-6)\\ \frac{1}{12}(12) +  \frac{1}{12} (-v) =  \frac{1}{6}(v)+  \frac{1}{6} (-6)  \\ 1 +  \frac{-1}{12}(v) =  \frac{1}{6}v + -01 \\  \frac{-1}{12} (v) +1  =  \frac{1}{6} - 1

Step two we have to subtract by \frac{1}{6}v on each of your sides (so it can kind of be easier for you to solve) 


So,\frac{1}{6} v  + 1 -  \frac{1}{6}v =  \frac{1}{6}v - 1  \frac{1}{6}v 
You would have to cancel out the right side because it would give you a(n) answer of 1 

Now that we got those steps out of your way, let's subtract 1 to your sides that we're working with 

\frac{-1}{4}(v) +1 -1 \\ = -1 -1

Finally we're close to our answer for v

\frac{-1}{4}(v)= 2

\frac{4}{1} ( \frac{-1}{4} ) cancel this out because it gives you one 

But, keep: \frac{4}{1} (-2) because it gives you the answer

v = 8

Good luck on your assignment
and enjoy your day

You have to first make like terms 

-\frac{2}{7} -(-  \frac{4}{3})-  \frac{1}{3} 

**you want the denominator to be 21 

\frac{-6+28-7}{21} =  \frac{15}{21}= \frac{5}{7}

Tema [17]

Answer:

For mileages higher than 80 miles Company A  will charge less than Company B

Step-by-step explanation:

Hi, to answer this question we have to write an inequality:

Company A charges $111 and allows unlimited mileage.

Company A =111

Company B has an initial fee of $55 and charges an additional $0.70 for every mile driven

Company B = 55+0.70m

Where m is the number of miles.

Company A has to charge less than Company B

a<b

111 < 55+0.70m

Solving for m

111-55 < 0.70 m

56 < 0.70m

56/0.70 < m

80 < m  

For mileages higher than 80 miles Company A will charge less than Company B

F(x) is a quadratic function with x-intercepts at (−1, 0) and (−3, 0). If the range of f(x) is [−4, ∞) and g(x) = 2x2 + 8x + 6,
svetlana [45]

Answer:

B) Both functions have the same domain.

C) Both functions have the same x-intercepts.

D) Both functions are decreasing on the interval (−∞, −2).

Step-by-step explanation:

step 1

Find the vertex of f(x)

we know that

The x-coordinate of the vertex is the midpoint of the roots

we have

x=-1 and x=-3

so

the midpoint is

(-1-3)/2=-2

The y-coordinate of the vertex is -4 (because the range is [−4, ∞))

therefore

The vertex of f(x) is the point (-2,-4)

Is a vertical parabola open upward

The vertex is a minimum

The domain is all real numbers

step 2

we have

g(x)=2x^2+8x+6

Find the vertex

Factor the leading coefficient

g(x)=2(x^2+4x)+6

Complete the square

g(x)=2(x^2+4x+4)+6-8

g(x)=2(x^2+4x+4)-2

Rewrite as perfect squares

g(x)=2(x+2)^2-2

Is a vertical parabola open upward

The vertex is the point (-2,-2)

The domain is all real numbers

The range is the interval [−2, ∞)

Find the x-intercepts

For g(x)=0

0=2(x+2)^2-2

2(x+2)^2=2

(x+2)^2=1\\x+2=\pm1\\x=-2\pm1

so

The roots or x-intercepts are

x=-1 and x=-3

<u><em>Verify each statement</em></u>

A) Both functions have the same vertex

The statement is false

The vertex of f(x) is (-2,-4) and the vertex of g(x) is (-2,-2)

B) Both functions have the same domain.

The statement is true

The domain is all real numbers

C) Both functions have the same x-intercepts

The statement is true  (see the explanation)

D) Both functions are decreasing on the interval (−∞, −2)

The statement is true

Because the x-coordinate of the vertex is the same in both functions, and both functions open upward

What is the smallest value of y in the solution set to the system of equations below?
n200080 [17]

Answer:

The smallest value of y in the given two equations is 78

Step-by-step explanation:

Given as :

The two equation is given as :

y = x² + 6 x +23               ...........1

y = 18 x - 12.                     ..........2

Now, solving both equations

putting the value of y from eq 2 into eq 1

So,  x² + 6 x +23 = 18 x - 12

Or,  x² + 6 x +23 - 18 x + 12 = 0

Or, x² - 12 x + 35 = 0

Or, x² - 5 x - 7 x + 35 = 0

Or, x (x - 5) - 7(x - 5) = 0

Or, (x - 5) (x - 7) = 0

∴ x = 5 , 7

Now, for smallest value of y , take x = 5

∴ put the value of x in eq 2

So, y = 18 x - 12

I.e y = 18 × 5 - 12

Or, y = 90 - 12

∴   y = 78

Hence, The smallest value of y in the given two equations is 78 . answer
