Y-1=1/4(x-12)
Y-1=1/4x-3
Y=1/4x-3+1
Y=1/4x-2
Now write it in standard form ax+by+c
-1/4x+y=-2
It’s better not to have a negative in front so y-1/4x=-2
Answer:
x = -10
Step-by-step explanation:
1.4x = -7.9 -6.1
1.4x = -14
x = -14÷1.4
x= -10
If you’re putting this in point slope form the answer is y=-3x+4 you just have to subtract 3x from both sides so only the y is on one side :)
Answers:
where 'a' cannot be zero.
=========================================================
Explanation:
The vertex is (h,k)
The x coordinate of the vertex is h which is found through this formula
For example, if we had the quadratic , then we'll plug in a = 3 and b = -6 to get:
------------
To find the value of k, we plug that h value into the original standard form of the quadratic and simplify.
It's interesting how we end up with the numerator of which is similar to found under the square root in the quadratic formula. There are other ways to express that formula above. We need to avoid dividing by zero. The values of b and c are allowed to be zero.
I believe the answer is 8.54, if you take 42.70 and multiply it by 20% you get 8.54!
