1) the vertex of a parable is given for two points, ( -b/2a, -b2-4ac/4a)
2) Now substitute the values in the equation
x = - (-8)/2(-2) = 8/ -4 = -2
y = -(8^2-4(-2)(1)/ 4(-2) = -(64-8) /-8 = 56/8 = 7
v(-2,7)
Answer:
The answer is A
Step-by-step explanation:
Start at (0,2) and draw a dot. Then, go up 2 units, and right 5 times. Draw a dot. Now connect the 2 dots and extend the line.
Now, it's graphed! :)
Answer:
9.5 m
Step-by-step explanation:
If width is -- x
12.4 + x + 12.4 + x = 43.8
2x = 19
x = (19/2)
x = 9.5 m
Thenks and mark me brainliest :))
Answer:
g(x) x^2 - 5
------ = --------- where x ≠ - 1/4
f(x) 4x+1
Step-by-step explanation:
f(x) = 4x+1
g(x) = x^2 - 5
g(x) x^2 - 5
------ = ---------
f(x) 4x+1
The denominator cannot equal zero
4x+1 ≠ 0
4x≠-1
x≠-1/4
g(x) x^2 - 5
------ = --------- where x ≠ - 1/4
f(x) 4x+1
