What is the equation of the line that is parallel to y-3x=2 and that passes through (6,1)?

Artemon [7]

Try this solution (analytic method):

1. if new line is parallel to the given one (y=3x+2) it means the new line has a form y=3x+b, where b - number.

2. In order to calculate 'b', it need to substitute the coordinates of point (6;1) into the equation of the new line:

1=3*6+b, ⇒ b=-17.

3. If to make up the equation of the new line:

y=3x-17

The sum of three numbers is 3068.Two of the numbers are 1266 and 1755,find the third number<br><br>

ratelena [41]

Answer:

The third number is 47.

Step-by-step explanation:

The sum of three numbers is 3068 - this can be expressed mathematically as:

$\displaystyle{x + y + z = 3068}$

Given that two of the numbers are 1266 and 1755 (in order) then substitute x = 1266 and y = 1755:

$\displaystyle{1266 + 1755 + z = 3068}$

Find the third number - solve for z-variable:

$\displaystyle{3021 + z = 3068}\\\\\displaystyle{z = 3068-3021}\\\\\displaystyle{z = 47}$

Therefore, the third number is 47.
