The answer for this is 1.39
Answer:
![5y +3x= 25](https://tex.z-dn.net/?f=5y%20%2B3x%3D%20%2025)
![3y -2x= - 12](https://tex.z-dn.net/?f=3y%20-2x%3D%20-%2012)
Step-by-step explanation:
An equation in standard form is:
![Ax + By = c\\](https://tex.z-dn.net/?f=Ax%20%2B%20By%20%3D%20c%5C%5C)
Solving (a):
Given
--- slope
--- y intercept
Required: Determine the equation
An equation has the form:
![y = mx + b](https://tex.z-dn.net/?f=y%20%3D%20mx%20%2B%20b)
Substitute values for m and b
![y = -\frac{3}{5}x + 5](https://tex.z-dn.net/?f=y%20%3D%20-%5Cfrac%7B3%7D%7B5%7Dx%20%2B%205)
Multiply through by 5
![5y = -3x + 25](https://tex.z-dn.net/?f=5y%20%3D%20-3x%20%2B%2025)
Add 3x to both sides
![5y +3x= 3x-3x + 25](https://tex.z-dn.net/?f=5y%20%2B3x%3D%203x-3x%20%2B%2025)
![5y +3x= 25](https://tex.z-dn.net/?f=5y%20%2B3x%3D%20%2025)
Solving (b):
Given
--- slope
--- y intercept
Required: Determine the equation
An equation has the form:
![y = mx + b](https://tex.z-dn.net/?f=y%20%3D%20mx%20%2B%20b)
Substitute values for m and b
![y = \frac{2}{3}x -4](https://tex.z-dn.net/?f=y%20%3D%20%5Cfrac%7B2%7D%7B3%7Dx%20-4)
Multiply through by 3
![3 * y = (\frac{2}{3}x -4) * 3](https://tex.z-dn.net/?f=3%20%2A%20y%20%3D%20%28%5Cfrac%7B2%7D%7B3%7Dx%20-4%29%20%2A%203)
![3y = 2x - 12](https://tex.z-dn.net/?f=3y%20%3D%202x%20-%2012)
Subtract 2x from both sides
![3y -2x= -2x+2x - 12](https://tex.z-dn.net/?f=3y%20-2x%3D%20-2x%2B2x%20-%2012)
![3y -2x= - 12](https://tex.z-dn.net/?f=3y%20-2x%3D%20-%2012)
Answer:
and ![y+1=\frac{4}{3}\left(x+2\right)](https://tex.z-dn.net/?f=y%2B1%3D%5Cfrac%7B4%7D%7B3%7D%5Cleft%28x%2B2%5Cright%29)

Answer:
<h2>3x²</h2>
Step-by-step explanation:
Given three functions 3x⁴, 15x³and 21x², the greatest common factor is the greatest value that can divide through the three functions at the same time.
To get this GCF, let us divide each functions into simplest form
3x⁴ = (3 *x * x) * x * x
15x³ = 5 * (3 * x * x) * x
21x² = 7 * (3 * x * x)
<em>It can be seen that the product in parenthesis is common to the three functions given on expanding them, </em><em>hence the greatest common factor of the three functions is 3 * x * x = 3x²</em>
