√(-80) = √(4²×5(-1)) = 4√5 √(-1) = 4√5i.
Answer: x^2+3
Step-by-step explanation:
If regular f(x) is equal to x^2, then if you just add 3 to the original, you add 3 to the same x^2. The three becomes a shift upwards on the graph. You put your vertex point up 3 on the vertical line then make your parabola
Answer:
c=15
8c-48+48=9c-63+48
8c=9c-15
8c-9c=9c-15-9c
\frac{-c}{-1}=\frac{-15}{-1}
c=15
Answer:
6,7
Step-by-step explanation:
The equation for this is 2 + n/5 = 10, where n is the number
