Answer:
<h2>3x - y + 7 = 0</h2>
Step-by-step explanation:
The slope-intercept form of an equation of a line:

m - slope
b - y-intercept
Put the given y-intercept b = 7 and the coordinates of the point (-2, 1) to the equation:
<em>subtract 7 from both sides</em>
<em>divide both sides by (-2)</em>

We have the equation:

Convert it to the general form
:
<em>subtract 3x and 7 from both sides</em>
<em>change the signs</em>

Answer:
x = 6
Step-by-step explanation:
7 x = 56-14
7 x = 42
7 x/7 to remain with x only = 42
then x = 6

Hi there!
Since a decimal is a portion of 1 we can simply put a 100 in the denominator to form it into a fraction.
By doing this, we get the fraction 29/100.
Since there is no simplifying we can do for the fraction this is it's final form!
Your answer would be 0.29 = 29/100.
