Answer:
B
Step-by-step explanation:
we are given a equation of a line
we want to figure out the equation of the perpendicular line passes through the <u>(</u><u>6</u><u>,</u><u>5</u><u>)</u><u> </u>points
in order to do so
recall that,
we got from our given equation that m=2
because equation of a line is y=mx+b
thus
remember that, when we want to figure out perpendicular line or parallel line we should the formula given by
since we got our perpendicular m is -½, and
, substitute
to get the perpendicular equation you should simplify the above equation to y=mx+b form
distribute -½:
add 5 to both sides:
hence,
our answer choice is B
Let
x--------> the number of gray bricks
y--------> the number of red bricks
we know that
------> inequality 1
<em>-----> </em>inequality 2
therefore
<u>the answer is</u>
x > 0
0.45x+0.58y≤200
