Answer: See the graph attached.
Step-by-step explanation:
The Slope-intercept form of the equation of the line is:
Where "m" is the slope and "b" is the intersection of the line with the y-axis.
Given the equation , you can identify that:
The line intercepts the y-axis when , therefore, you can know that the line passes through the point:
(0,3) → Point of intersection with the y-axis.
Now, substitute and solve for "x" to find the point of intersection with the x-axis:
Now, you know that the line also passes through the point:
(-6,0) → Point of intersection with the x-axis.
Draw the a line that passes through these points.
Therefore, you get the graph attached.
ANSWER
to the nearest thousandth.
EXPLANATION
The given irrational number is
We use the calculator to evaluate this to obtain,
To round to the nearest thousandth means we are rounding to 3 decimal places.
The third decimal place is 5.
The next number is 5 so we round up.
440 gallons of 80 % antifreeze solution must be mixed with 80 gallons of 15% antifreeze to get a mixture that is 70% antifreeze
<em><u>Solution:</u></em>
Let "x" be the gallons of 80 % antifreeze added
Therefore, "x" gallons of 80 % antifreeze solution must be mixed with 80 gallons of 15% antifreeze
Final mixture is x + 80
Therefore, we can frame a equation as:
"x" gallons of 80 % antifreeze solution must be mixed with 80 gallons of 15% antifreeze to get (x + 80) gallons of 70 % antifreeze
Thus, we get,
x gallons of 80 % + 80 gallons of 15 % = (x + 80) gallons of 70 %
Thus 440 gallons of 80 % antifreeze solution must be mixed
