Answer:
Step-by-step explanation:
Two lines are perpendicular if the first line has a slope of
and the second line has a slope of
.
With this information, we first need to figure out what the slope of the line is that we're given, and then we can determine what the slope of the line we're trying to find is:
![5x - 2y = -6](https://tex.z-dn.net/?f=5x%20-%202y%20%3D%20-6)
![-2y = -5x - 6](https://tex.z-dn.net/?f=-2y%20%3D%20-5x%20-%206)
![y = \frac{5}{2}x + 3](https://tex.z-dn.net/?f=y%20%3D%20%5Cfrac%7B5%7D%7B2%7Dx%20%2B%203)
We now know that
for the first line, which means that the slope of the second line is
. With this, we have the following equation for our new line:
![y = \frac{-2}{5}x + C](https://tex.z-dn.net/?f=y%20%3D%20%5Cfrac%7B-2%7D%7B5%7Dx%20%2B%20C)
where
is the Y-intercept that we now need to determine with the coordinates given in the problem statement,
:
![y = \frac{-2}{5}x + C](https://tex.z-dn.net/?f=y%20%3D%20%5Cfrac%7B-2%7D%7B5%7Dx%20%2B%20C)
![(-4) = \frac{-2}{5}(5) + C](https://tex.z-dn.net/?f=%28-4%29%20%3D%20%5Cfrac%7B-2%7D%7B5%7D%285%29%20%2B%20C)
![-4 = -2 + C](https://tex.z-dn.net/?f=-4%20%3D%20-2%20%2B%20C)
![C = -2](https://tex.z-dn.net/?f=C%20%3D%20-2)
Finally, we can create our line:
![y = \frac{-2}{5}x - 2](https://tex.z-dn.net/?f=y%20%3D%20%5Cfrac%7B-2%7D%7B5%7Dx%20-%202)
![5y = -2x - 10](https://tex.z-dn.net/?f=5y%20%3D%20-2x%20-%2010)
![2x + 5y = -10](https://tex.z-dn.net/?f=2x%20%2B%205y%20%3D%20-10)

Answer:
Length: 84 ft
Width: 56 ft
Step-by-step explanation:
Let's define some variables first.
Call the length l and width w.
We know that w = 2/3l. Therefore, we can express w in terms of l with this expression.
Now, let's set up an equation. The flower garden is rectangular, and 280 feet of fencing are used to enclose the garden. This represents perimeter.
Remember the formula for perimeter of a rectangle: 2l + 2w
Let's substitute 2/3l for w:
2l + 2*2/3l = P
2l + 4/3l = 280
2 4/3l = 280
10/3l = 280
l = 84
Now, we know that the length is equal to 84 feet. We can multiply 84 feet by 2/3 to find the width.
84*2/3 = 56
Length: 84 ft
Width: 56 ft
Let's plug these values into the formula and see if they give us the correct perimeter:
2l + 2w = P
2*84 + 2*56 = P
168 + 112
= 280 feet
These are the correct dimensions!

Answer:
The number is 5
Step-by-step explanation:
If we need to find the hidden number, Which for simplicity's sake we will denote as "n", lets first write out the equation.
"2 x [n + (-3)] = 4"
We can work through this problem backwards. if we need two times the sum of "n" and (-3) to get to 4, the only number that can be multiplied by 2 to get a product of 4 is 2, so "n" + (-3) must equal 2. so, From here, we can figure out that since 5 + (-3) equals 2, "n" Must equal 5. so, if we plug in 5 for "n" the equation looks like this:
"2 x [5 + (-3)] = 4"
So, since the equation makes sense, the answer is, "n = 5"
