The system of the equation doesn't give the solution at (-3, -6).
<h2>Given to us</h2>
<h3>Equation 1,</h3>
-4x+y = 6
solve for y

<h3>Equation 2,</h3>
5x-y =21
substitute the value of y in equation 2,

Substitute the value of x in equation 2,

We can see that the solution of the two equations is at (27, 114). Also, it can be verified by plotting the line on the graph.
Hence, the system of the equation doesn't give the solution at (-3, -6).

Answer:
maximum number: 171
Step-by-step explanation:
The $500 budget that will serve the people (x) with flat fee of $200 and $1.75 per person
1.75x + 200 = 500
1.75 x = 300
x = 171.4
<h3>

are the slopes of perpendicular lines</h3>
<em><u>Solution:</u></em>
We know that,
Product of slope of a line and slope of line perpendicular to it is always equal to -1
<em><u>Option 1</u></em>


Thus, these are not the slopes of perpendicular lines
<em><u>Option 2</u></em>

This option satisfies the slopes of perpendicular lines
<em><u>Option 3</u></em>

Thus, these are not the slopes of perpendicular lines
<em><u>Option 4</u></em>
2 and 2
Product = 2 x 2 = 4
Thus, these are not the slopes of perpendicular lines
