When solving an equation, you must do the same thing to both sides or else it won't be equal

when dealing with one unknown (x) try to get the unknown on one side

2(x-3)=1.2-x
distribute or multiply 2 by x then -3

so (2 times x)+(2 times -3[remember negative times positive=negative])
2x-6=1.2-x
add 6 to both sides
2x=7.2-x
add x to both sides
3x=7.2
divide both sides by 3
x=2.4

2(x-3) = 1.2-x
2x-6 = 1.2-x
2x+x = 1.2+6
3x = 7.2
3x/3 = 7.2/3
x = 2.4

Write the equation of a line in slope-intercept form that is parallel to the given line and passes through the point (12,-25).

lina2011 [118]

Answer:

$m_1 = m_2 = \frac{1}{4}$

And then since the new equation have the following form:

$y = m_2 x +b$

We can use the point given (x=12, y = -25) in order to find the intercept with this equation:

$-25 = \frac{1}{4} (12) +b$

And solving for the intercept b we got:

$-25 = 3 +b$

We subtract in both sides 3 and we got:

$b = -25-3 = -28$

And our final equation who satisfy the condition given is:

$y= \frac{1}{4} x -28$

Step-by-step explanation:

For this case we have the following equation given:

$y = \frac{1}{4} x + 2$

And we want to find an equation of a line parallel to the given function and this case we need to satisfy this condition:
