f(x) = 5x^2 - 4x
g(x) = 5x + 1
Therefore f - g = 5x^2 - 4x - (5x + 1)
= 5x^2 - 4x - 5x -1
= 5x^2 -9x - 1
Hope it helps :)
Final Answer: 
Steps/Reasons/Explanation:
Question: Solve by using the quadratic formula:
.
<u>Step 1</u>: Use the Quadratic Formula.
![x = \frac{6 + \sqrt[2]{2} }{2}, \frac{6 - \sqrt[2]{2} }{2}](https://tex.z-dn.net/?f=x%20%3D%20%5Cfrac%7B6%20%2B%20%5Csqrt%5B2%5D%7B2%7D%20%7D%7B2%7D%2C%20%5Cfrac%7B6%20-%20%5Csqrt%5B2%5D%7B2%7D%20%7D%7B2%7D)
<u>Step 2</u>: Simplify solutions.

~I hope I helped you :)~ The quadratic formulaic is attached in an image.
From the graph we can see that the horiz. directrix is 1 unit down from the vertex, which in turn is (1,4). The focus is located the same distance (1) upward from the vertex, that is, at (1, 5).
Answer:
Terms: 4b, 7b, 5
Like Terms: 4b, 7b
Coefficients: 4, 7
Constants: 5
Step-by-step explanation:
Terms: the numbers in an equation
Like Terms: terms that have the same variables
Coefficients: numbers that are next to a variable
Constants: numbers that don't have a variable
Well since all of them are the same we have to look for one common number and given that they are all acute angles id say its about 30 or 50
