Answer:
135 square ft.
Step-by-step explanation:
To solve this equation, you need to find the area of this rectangle. Area is always base x height, or in this case, length x width. Now you multply your length, 15', by your width, 9', to get your answer, 135 square feet. When you multiply two measurments of the same unit together, you get square (units), which simply means that you multiplied two of the same unit of measurment together.
X = 3y - 6 so:
2(3y - 6) - 4y = 8
6y - 12 - 4y = 8
2y - 12 = 8
2y = 20
y = 10
x = 3(10) - 6
x = 30 - 6
x = 24
Answer:
![y = -8x - 39](https://tex.z-dn.net/?f=y%20%20%3D%20%20-8x%20-%2039)
Step-by-step explanation:
First, find the <em>rate of</em><em> </em><em>change</em><em> </em>[<em>slope</em>]:
-y₁ + y₂\-x₁ + x₂ = m
![\frac{7 + 9}{4 - 6} = -\frac{16}{2} = -8](https://tex.z-dn.net/?f=%20%5Cfrac%7B7%20%2B%209%7D%7B4%20-%206%7D%20%20%3D%20%20%20-%5Cfrac%7B16%7D%7B2%7D%20%3D%20%20-8)
Then use the Point-Slope Formula since we are given points. Now, according to this formula, all negative symbols give the OPPOSITE terms of what they really are, so be EXTREMELY careful inserting the coordinates into the formula with their CORRECT signs. It does not matter which one you choose:
y - y₁ = m(x - x₁)
y - 9 = -8(x + 6)
y - 9 = -8x - 48
+ 9 + 9
______________
y = -8x - 39
__________________________________________________________
y + 7 = -8(x + 4)
y + 7 = -8x - 32
- 7 - 7
______________
y = -8x - 39
** You see? I told you it did not matter which ordered pair you choose because you will always get the exact same result.

Answer:
20.398 miles
Step-by-step explanation:
The total distance ran would be the sum of the distances they ran.
5.12 + 7.278 + 8 = 12.398 +8 = 20.398 miles
