Answer:
Area of the rectangular pen is:
Step-by-step explanation:
We need to specify that the perimeter of the rectangular area of side x adds to the amount of fence Pablo has (36 feet). Recall as well that the opposite sides of a rectangle are equal, so if there is a side of length x, there must be another one of this size as well (a total of 2 x in the perimeter),let's assume that the perpendicular sides to x are of length y, then:
Perimeter= 2 x + 2 y = 36
so, 2 (x+y) = 36 then (x+y) = 18
and therefore the side y should be:
y = 18 - x
Now we can write the formula for representing the area of the rectangle (product of both quantities: x * y
The equation of the line that passes through the point (5,4) and is perpendicular to the line whose equation is 2x + y = 3 in standard form is x - 2y = - 3
<u>Solution:</u>
Given, line equation is 2x + y = 3
2x + y – 3 = 0 ----- eqn (1)
We have to find a line that is perpendicular to 2x + y – 3 = 0 and passing through (5, 4).
Now, let us find the slope of the given line,
Now, slope of our required line = 1/2 and it passes through (5, 4)
<em><u>The point slope form is given as:</u></em>
<em><u>Now let us convert to standard form:</u></em>
The standard form of a line is just another way of writing the equation of a line.
The standard form of an equation is Ax + By = C. In this kind of equation, x and y are variables and A, B, and C are integers.
2(y – 4) = 1(x - 5)
2y – 8 = x – 5
x – 2y - 5 + 8 = 0
x - 2y + 3 = 0
x - 2y = - 3
Hence, the line equation in standard form is x - 2y = - 3
