Answer:
Step-by-step explanation:
The distance between two points A(x₁,y₁) B(x₂,y₂) is given by the formula as follows :
It is used to find the distance between two points. It is an application of the Pythagorean theorem. Usually, the distance covered is equal to the product of speed and time. But when speed and time in not given but coordinates are given, then only we can use this formula.
First you need to distribute : -4x + 8x - 3
Combine like terms : 4x -3
The answer to the question
the 1 is the h and the -2 is the k
f(x) = a(x - h)^2 + k
f(x) = a(x-1)^2 -2
to find a substitute x=3, y=6 in
6= a(3-1)^2 -2
6 =a *2^2 -2
add 2 to each side
8 = 4a
a =2
f(x) = 2(x-1)^2 -2 this is the vertex form
distribute to get the standard from
f(x) = 2(x^2-2x+1) -2
2x^2 -4x+2-2
f(x) =2x^2-4x is the standard form
Choice A
Answer:
x=10
Step-by-step explanation:
3x-8=22
3x-8+8=22+8
3x=30
3x/3=30/3
