Step-by-step explanation:
y=x(x+3)-1(x+3)
y= x^2+3x-x-3
y=x^2+2x-3
that is the answer
The equation of the line which is plotted on the graph and passes from the points (2,5) and (-2,-3) is y=2x-6.
<h3>What is the equation of line?</h3>
The equation of the line is the way of representation of a line in the equation form.
The equitation of the lines represents the line by the set of points on which the line lies or passes through in the coordinate system.
The formula to find equation of line is,
(y-y₁)={(y₂-y₁)/(x₂-x₁)}(x-x₁)
Here, x and y are the coordinate and subscript (1,2) used for the first and second point.
The points from which the line passes through are (2,5) and (-2,-3). Put the values,
(y-y₁)={(y₂-y₁)/(x₂-x₁)}(x-x₁)
(y-(-2))={(-3-5)/(-2-2)}(x-2)
y+2={-8/-4}(x-2)
y+2=2(x-2)
y+2=2x-4
y=2x-4-2
y=2x-6
Thus, the equation of the line which is plotted on the graph and passes from the points (2,5) and (-2,-3) is y=2x-6.

<span>The correct answer is 50,000.
Explanation<span>:
We can set up the equation 5000=1/10x to represent this situation.
To solve, we will divide both sides by 1/10:
5000</span></span>÷<span><span>(1/10) = (1/10x)</span></span>÷<span><span>(1/10)
5000</span></span>÷<span><span>(1/10) = x.
To divide fractions, flip the second one and multiply; this gives us
5000*(10/1) = x
50000 = x.</span></span>
Say the number of adult tickets is x. That means the number of student tickets is 71 less, making it x - 71.
We can add the number of student and adult tickets, because we know their sum is 479.
x + x - 71 = 479
Now, we solve for x.
2x - 71 = 479
2x = 550
x = 275
So, there were 275 adult tickets sold.
