Answer: 0=x


Step-by-step explanation: First we need to combine like terms.

3 = x + 3 + 6x

3=3+7x

Then we subtract 3 from both sides.

3=3+7x

0=7x

Finally we divide both sides by 7

0=7x

0/7=7x/7

0=x

Hope this helps!

Answer:

x=0

Step-by-step explanation:

3 = x + 3 + 6x

Combine like terms

3=7x + 3

Use order of operations to isolate x

3=7x + 3

-3       -3

0/7=7x/7

x=0/7 or 0

Idk this is supper hard
vlabodo [156]

Answer:

The equation of the line is:  y = x + 4

Step-by-step explanation:

When we are given two points passing through a line, we can find the equation of the line by using two - point form.

Two - point form:    $ \frac{\textbf{y - y}_\textbf{1}}{\textbf{y}_{\textbf{2}} \textbf{-} \textbf{y}_{\textbf{1}}} = \frac{{\textbf{x - x}_\textbf{1}}}{\textbf{x}_{\textbf{2}} \textbf{-} \textbf{x}_{\textbf{1}}    }$

where $ (x_1, y_1) \hspace{3mm} \& \hspace{3mm} (x_2, y_2) $ are the points passing through the line.

Here, let us take two points (can be any two):

$(x _1, y_1) = (1, 5) $ and

$ (x_2, y_2) = (5, 9) $

Therefore, we have:

$ \frac{y - 5}{9 - 5} = \frac{x - 1}{5 - 1} $

$ \iff \frac{y - 5}{4} = \frac{x - 1}{4} $

$ \iff y - 5 = x - 1 $

$ \implies y = x - 1 + 5 $

$ \implies y = \textbf{x + 4} $ which is the required answer.

igomit [66]

Answer:

f(3) just means to substitute 3 in for x.

Step-by-step explanation:

f(3) just means to substitute 3 in for x.  

f

(

)

=

−

2

Explanation:

f

(

)

=

−

(

3

)

2

+

7

According to the order of operations, first square the 3, which is 9.

f

(

3

)

=

−

9

+

7

The negative sign in front of the x squared is equivalent to multiplying by negative one.

Add -9 and 7 together, which is -2

So,  

f

(

3

)

=

−
