Answer:
you have to solve the system:
1)W=L-6
2)W*L=72
so (L-6)*L=72
L^2-6L-72=0
(L-12)*(L+6)=0
so the answers for L are 12 and -6,but we only consider 12 cause there can't be -6miles. so L=12
and W=12-6, so W=6.
Answer:
Width = 6mi
Length = 12mi
Step-by-step explanation:
Let's say our length = x
Since the width is 6 miles less than the length, width = x - 6
The area of rectangle is width x length so just substitute your values
(x - 6)(x) = 72
therefore: x^2 - 6x = 72
*subtract 72 to form a quadratic equation
x^2 - 6x - 72 = 0
*solve by factorising
(x+6)(x-12) = 0
therefore x = -6 or 12
Since you can't have a negative length, x = 12
thus, our length is 12mi
To find the width, just subtract 6 which = 6mi
So: length = 12mi and width = 6mi

how would I graph the line, 3x+4y= -4
Given the equation:
3x + 4y = -4
Let's graph the line that represents the equation above.
To grah the line, rewrite the equation in slope-intercet form:
y = mx + b
Where m is the slope and b is the y-intercept.
Rerite the equation for y:
3x + 4y = -4
Subtract 3x from both sides:
3x - 3x + 4y = -3x - 4
4y = -3x - 4
Divide all terms by 4:
[tex]\begin{gathered} \frac{4y}{4}=-\frac{3x}{4}-\frac{4}{4} \\ \\ y=-\frac{3}{4}x-1 \end{gathered}[/tex]The slope of the line is -3/4, while the y-intercept is at (0, -1).
Now, let's graph the line using 3 points.
• When x = -4:
Substitute -4 for x and solve for y
[tex]\begin{gathered} y=-\frac{3}{4}\ast(-4)-1 \\ \\ y=3-1 \\ \\ y=2 \end{gathered}[/tex]• When x = 0:
Substitute 0 for x and solve for y
[tex]\begin{gathered} y=-\frac{3}{4}\ast(0)-1 \\ \\ y=-1 \end{gathered}[/tex]• When x = 4:
Substitute 4 for x and solve for y
[tex]\begin{gathered} y=-\frac{3}{4}\ast4-1 \\ \\ y=-3-1 \\ \\ y=-4 \end{gathered}[/tex]Therefore, we have the following points:
(-4, 2), (0, -1) and (4, -4)
Plot the three points on the graph, then connect all 3 points using a straight edge.

Draw the figure and its rotation as described. Identify the coordinates of the image. J(−4, 1), K(−2, 1), L(−4,−3) 90° clockwise about vertex L.
The new coordinates of the image after rotation are L′(−4,1), J′(0,−3), and K′ (0,−5).
Step 1:
The first thing we have to do is to graph the figure. We will color it red. The graph is shown below:
Step 2:
We know that the distance between L and J is 4 units upward. If we rotate it 90° clockwise, the direction will become right. Therefore,
J′ is 4 units to the right of L. We can see that the distance between
J and K is 2 units to the right. If we rotate it 90° clockwise, the direction will become downwards. Therefore, K′ is 2 units down of L′.
Then, connect L and K′ to complete the figure. The new coordinates are L′(−4,1), J′(0,−3), and K′ (0,−5). We will graph it and color it blue.
Hence the answer is the new coordinates of the image after rotation are L′(−4,1), J′(0,−3), and K′ (0,−5).

i)
The vertex form of a quadratic equation of a parabola opening upwards or downwards is,
[tex]y=a(x-h)^2+k\ldots\ldots(1)[/tex]Here, (h,k) is the coordinates of the vertex of the parabola. If a is positive, the parabola is facing up and if a is negative, the parabola is facing down.
The given equation of parabola is,
[tex]y=(x+2)^2-5\ldots\ldots(2)[/tex]So, the given equation is in the vertex form of the quadratic equation.
Comparing equations (1) and (2), we get
a=1, h=-2, k=-5.
Since a is positive, the parabola opens upwards. The coordinates of the vertex of the parabola is (-2,-5).

What is the slope of the line that passes through the points (12, -13) and (-18, 11)? Round your answer to the nearest tenth.
The slope of the line is 0.8.
What is slope of the line?
The slope of a line is also called its gradient or rate of change. The slope formula is the vertical change in y divided by the horizontal change in x, sometimes called rise over run. The slope formula uses two points, (x1, y1) and (x2, y2), to calculate the change in y over the change in x.
slope of the line = (y2-y1)/x2-x1
Here, the points are (12,-13) and (-18,11)
x1=12,y1=-13, x2=-18, y2=11
m (slope of line) = 11+13/(-18-12)
