Step-by-step explanation:

2/7+5/7=7/7=1 because 7/7 would be a 1 whole

Answer:

35/7

Step-by-step explanation:

4 = 28/7

28/7 + 2/7 + 5/7 = 35/7

Answer:

it is a b and c

Step-by-step explanation:

Hi how u doin ?

[tex] log( \frac{x}{x + 1} ) = \\ [/tex]

[tex] log(x) - log(x + 1) [/tex]

Have a great day ❤

yessssss I cannnnnnn helppppp youu

[tex] \frac{ - 12}{c} = 6 \\ [/tex]

Inverse both sides

[tex] - \frac{c}{12} = \frac{1}{6} \\ [/tex]

Multiply both sides by - 12

[tex]( - 12) \times - \frac{c}{12} = ( - 12) \times \frac{1}{6} \\ [/tex]

[tex]c = - 2[/tex]

There u go have a great day ❤

Answer:  C = -2

Step-by-step explanation:  Well if you times 2x3 that = 12.  So -2= c.

I am really sorry if this is wrong. I tried my best.  :-)

Hope you have a wonderful day !

Option B) 13 is correct

Step-by-step explanation:

Answer:

25

Step-by-step explanation:

turn 68% into a decimal (or keep as a percentage, your choice) and divide

17 divided by 0.68 (68% as a decimal) = 25

Answer: f(-9)

Step-by-step explanation:

A function is described in the form of f(x)

Therefore, if this is how a function is stated we have x as the input.

Here, the x is equal to -9

So now:

f(-9) after substitution.

Answer:

  x = 6

Step-by-step explanation:

12(x -2) +3x = 1/3(x +12) +10x

12x -24 +3x = 1/3x +4 +10x . . . . . eliminate parentheses

15x = (10 1/3)x +28 . . . . . . . . . . add 24, collect terms

(4 2/3)x = 28 . . . . . . . . . . . . . subtract 10 1/3

x = (3/14)(28) = 6 . . . . . . . . multiply by 1/(4 2/3) = 3/14

The value x=6 satisfies the equation.

Answer:

y = - 1/7x - 7

Step-by-step explanation:

Given equation ,

=> y = -1/7 - 2

On comparing to slope intercept form of the line we get the slope as -1/7

Now as we know that the slope of two parallel lines are same . So the slope of parallel line will be -1/7 .

Using point slope form ,

=> y - 6 = -1/7( x -7)

=> y -6 = -1/7x +1

=> y -7 = -1/7x

=> y = -1/7x -7

Answer:

multiply them by a a number that allows the denominators to be the same

Step-by-step explanation:

example

1/2-1/6

I would multiply 1/2 by 3 to get 3/6 which i could then subtract from 1/6

3/6-1/6 = 2/6

(7,5) not solution for 2x+y

Step-by-step explanation:

2(7) + 5 =19 which is not 5,

possible answer for X/Y

(0,5)

(7,-9)

Okay, suppose your income is about $100.

You might spend $70 & save $30.

Now, suppose your income remains constant at $100 but your expenses go up to, say, $90. You can see that your savings will reduce or decrease. Now, you'll only have about $10 to save.

=》 So, if your income is constant, then your savings will 'decrease' when your expenses increase.

=−913+113

=−800

Answer:

F =672

Step-by-step explanation:

joint variation is of the form

F = k *q1 * q2

Inversly means divide

F = k * q1 * q2

     -------------------

              d^2

We know  F=8 when q1=2, q2=8, and d=4  so we can solve for k

8 = k * 2*8

    -----------------

          4^2

8 = 16k

     ----

     16

8 = k

Substituting

F = 8 * q1 * q2

     -------------------

              d^2

Let q1=28, q2=12, and d=2

F = 8 * 28 * 12

   ----------------

    2^2

F = 2688

      -------

         4

F =672

We are given:

F varies jointly (directly) with q1 and q2, which means that F is proportional to both q1 and q2. also,

F varies inversely with d², so F is inversely proportional to the square to d

Finding a mathemetical experssion:

using the above information, we can say that:

F ∝ q₁

F ∝ q₂

F ∝ 1/(d²)

joining these together, we get:

F ∝ q₁q₂ / d²

let's say that 'k' is the constant of proportionality in this case,

F = k (q₁q₂ / d²)

First case:

F = 8, q₁ = 2, q₂ = 8, d = 4

we can use these values in our expression to find k

[tex]8 = k\frac{2*8}{4^2}[/tex]

[tex]8 = k\frac{16}{16}[/tex]

k = 8

Finding F in the second case:

q₁ = 28, q₂ = 12, d = 2, k = 8

[tex]F = k\frac{q_{1}*q_{2}}{d^2}[/tex]

[tex]F = 8(\frac{28*12}{2^2})[/tex]

[tex]F = 8(\frac{336}{4})[/tex]

[tex]F = 2(336)[/tex]

F = 672 N
