<u><em>The correct question is</em></u>
What is the equation of a line passing through the point (3, 2) and parallel to the line y=5x+4
step 1
Find the slope of the given line
we have
This is the equation of the line in slope intercept form
The slope is
step 2
Find the slope of the line parallel to the given line
we know that
If two lines are parallel, then their slopes are equal
so
The slope is
step 3
Find the equation of the line in point slope form
we have
substitute
step 4
Convert to slope intercept form
isolate the variable y
Answer:
50 soldiers must be transferred elsewhere.
Step-by-step explanation:
We solve this question by proportions, using a rule of three.
As the number of soldiers decrease, the provisions last for more time. This means that the measures are inversely proportional, and we have an inverse rule of three, using line multiplication, instead of cross.
30 days of provisions - 200 soldiers
40 days of provisions - x soldiers
Simplifying by 40
The provisions will last for 40 days with 150 soldiers, which means that 200 - 150 = 50 soldiers must be transferred elsewhere.
