This is extremely grammatically incorrect but I will try my best to answer. If a package of books has 10 books and all 10 together cost 5 euro and 10 pencils cost 4.50 euro then 5 / 10 is 0.5 euro so 0.5 + (4.50 / 10) = 0.45 euro! So your answer is 0.45 euro
So basically what you would is u would plug the first equation into the second equation. -5x+21=4x+6
-21 -21
-5x=4x-15
-4x -4x
-9x=-15
-9x/-9=15/-9
x=-1.66
then you would plug x back into the equation to get your y value
y=4(-1.66)+6
y=6.64+6
y=12.64
<em>Answer:</em>
<em>0 because 0 is sea level, anything below is negative and anything above is positive.</em>

It is four fluid ounces. Just divide 3 by 27 and convert to fluid ounces.
From the equation the slope is -1/3 and the y-intercept is -3/2. This shows that the intercept must pass through the y-axis at -3/2.
<h3>Equation of a line</h3>
A line is defined as the shortest distance between two points. The formula for finding the equation of a line in slope-intercept form is given as;
y = mx + b
The point sloe form of the equation is given as y-y1 = m(x-x1)
where
- m is the slope
- b is the intercept
- (x1, y1) is any point on the line
Given the equation of graph to plot
y=-x/3 -3/2
From the equation the slope is -1/3 and the y-intercept is -3/2. This shows that the intercept must pass through the y-axis at -3/2.
