Y + 2x = 5
y = 5 - 2x, x = -1, 0 , 3
When x = -1, y = 5 - 2*(-1) = 5 +2 = 7, y = 7
When x = 0, y = 5 - 2*(0) = 5 -0= 5, y = 5
When x = 3, y = 5 - 2*(3) = 5 - 6 = -1, y = -1
A snowflake falls 90 feet in 1 minute.
60 ÷ 4 = 15
6 x 15 = 90

The result of
is ![x^3 + 13x^2+ 55x+ 75](https://tex.z-dn.net/?f=x%5E3%20%2B%2013x%5E2%2B%2055x%2B%2075)
<h3>Composite functions</h3>
Composite functions are functions that are gotten by combining multiple functions
<h3>The functions</h3>
The functions are given as:
![f(x) = x^2 + 8x + 15](https://tex.z-dn.net/?f=f%28x%29%20%3D%20x%5E2%20%2B%208x%20%2B%2015)
![g(x) = x+5](https://tex.z-dn.net/?f=g%28x%29%20%3D%20x%2B5)
To calculate f(x) * g(x), we have:
![f(x) \times g(x) = [x^2 + 8x + 15] \times [x + 5]](https://tex.z-dn.net/?f=f%28x%29%20%5Ctimes%20g%28x%29%20%3D%20%5Bx%5E2%20%2B%208x%20%2B%2015%5D%20%5Ctimes%20%5Bx%20%2B%205%5D)
Expand the above expression
![f(x) \times g(x) = x^3 + 8x^2 + 15x + 5x^2 + 40x + 75](https://tex.z-dn.net/?f=f%28x%29%20%5Ctimes%20g%28x%29%20%3D%20x%5E3%20%2B%208x%5E2%20%2B%2015x%20%2B%205x%5E2%20%2B%2040x%20%2B%2075)
Collect like terms
![f(x) \times g(x) = x^3 + 8x^2 + 5x^2+ 15x + 40x + 75](https://tex.z-dn.net/?f=f%28x%29%20%5Ctimes%20g%28x%29%20%3D%20x%5E3%20%2B%208x%5E2%20%2B%205x%5E2%2B%2015x%20%20%2B%2040x%20%2B%2075)
Evaluate the like terms
![f(x) \times g(x) = x^3 + 13x^2+ 55x+ 75](https://tex.z-dn.net/?f=f%28x%29%20%5Ctimes%20g%28x%29%20%3D%20x%5E3%20%2B%2013x%5E2%2B%2055x%2B%2075)
Hence, the result of
is ![x^3 + 13x^2+ 55x+ 75](https://tex.z-dn.net/?f=x%5E3%20%2B%2013x%5E2%2B%2055x%2B%2075)
