Answer:
vertex = (- 3, 2 )
Step-by-step explanation:
The equation of a parabola in vertex form is
y = a(x - h)² + k
where (h, k) are the coordinates of the vertex and a is a multiplier
y = - 4(x + 3)² + 2 ← is in vertex form
with (h, k ) = (- 3, 2 )
Answer:
12
Step-by-step explanation:
Since 20 is 2 x 10, you can multiply the value for 2 kilometers by 10 and get 12.
Depends on the formula, but with most cases yes, because you may have -3 as an answer, but adding only 4 makes it positive.
There are some cases where you could look at it and know the sign, like if I am adding -100 and -93, I know the answer will be negative
