Answer:
17
Step-by-step explanation:
angle one and angle three are equal to each other
so if you set the equations equal to each other
(4x+2)=( 5x-15)
move the 4x the right by subtracting it giving you 1x
then add 15 to 2 giving you 17 
17=1x
 
        
             
        
        
        
You know if something is a function or not because the X will never be used twice in a set. If it is, then it's not a function.
A. Uses -1 twice
B. Uses Nothing twice (good)
C. Uses 0 twice
D. Uses 0 twice
B is your answer
        
             
        
        
        
Answer:
Step-by-step explanation:
y = (x^2 + 4x)      + 2
Take 1/2 of the linear term 4/2 = 2 and square that result. 2^2 = 4.
Put it after 4x
y = (x^2 + 4x + 4)   +2  Subtract what you put inside the brackets on the outside.
y = (x^2 + 4x + 4) + 2 - 4      Combine the right.
y = (x^2 + 4x + 4) - 2            Express the brackets as a square.
y = (x + 2)^2 - 2
That's your answer
a = 1
h = 2
k = -2
 
        
             
        
        
        
Answer:
Step-by-step explanation:
x +3 I x⁴ + 0x³ - 6x² + 0x  -28 I x³ - 3x² + 3x - 9
          x⁴ + 3x³
        <u>-       -      </u>
                 -3x³ - 6x²
                 -3x³ - 9x²
                <u>  +      +     </u>
                         3x² + 0x
                        3x²  + 9x
                        <u> -       -       </u>
                                 -9x  -28
                                 -9x  - 27
                                 <u> +      +    </u>
                                          -1
P(x) =(x +3)* (x³ - 3x² + 3x - 9) + (-1)
