Answer:
f(6) = 10, f(10) = 30, f(20) = 80
Step-by-step explanation:
Plug in the values into the equation and compute. 5*6 - 20 = 10, 5*10 - 20 = 30, 5*20 - 20 = 80.
 
        
             
        
        
        
Answer:
x = -2
Step-by-step explanation:
Equation is given as;
 4 x - 5 = 2 + 3 ( x - 3 )
Step 1: Expand the brackets
4x - 5 = 2 + 3x - 9
Step 2: Collect like terms
4x - 3x = 2 - 9 - (-5)
Step 3: Simplify
x = 2 - 9 + 5
x = -2

 Here, we need to set up an equation. So since the two angles need to add up to 90, and x will represent the angle, the initial equation will look like this. x=90-x. When you plugin the 14, it will look like x=14(90-x) and that gives you x=1490-14x. Add the 14x to the left and it becomes 15x=1490. Divide by 15 and you get x=84. That is the first angle. Now, we subtract 84 from 90 and we get 6. therefore the angles are 84 and 6 degrees.
Hope this is clear enough.
