Answer:

2n-7

Step-by-step explanation:

"7 less than twice a number n"

is the same as

"7 less than (twice a number n)".

I put ( ) around that one part because I want you to focus on that part first.

Twice a number n means 2 times that number n or 2n.

So now we have

"7 less than 2n".

This means 2n-7.

Which point lies on the line described by the equation below? y+ 4 = 4(x-3) O A. (3,-4) O B. (2,9) O C. (0,0) O D. (1,-11) E. (1
dangina [55]

The point (3, -4) lie on the line y + 4 = 4(x - 3) because the point (3,-4) satisfy the line option (A) is correct.

<h3>What is a straight line?</h3>

A straight line is a combination of endless points joined on both sides of the point.

The slope 'm' of any straight line is given by:

\rm m =\dfrac{y_2-y_1}{x_2-x_1}

We have an equation of a line:

y + 4 = 4(x - 3)

A (3,-4)  

Plug the above points in the equation of the line.

-4 + 4 = 4(3 -3)

0 = 0    (true)

The point lies on the line

Similarly checking for others points we will find that points (2,9), (0,0) , (1,-11), (1,11), and (-2, 3) does not lie on the line y + 4 = 4(x - 3)

Thus, the point (3, -4) lie on the line y + 4 = 4(x - 3) because the point (3,-4) satisfy the line option (A) is correct.
