22.5
Answer:
hi
Step-by-step explanation:
hi
Y2 - y1/x2 - x1 = slope
4 - 8/ 9 - 5 = slope
-4/4 = slope
-1 = slope
hope this helps :)
First, make the mixed fraction into improper fraction,
x−12=54
Add 1/2 on both sides
x−12+12=54+12
Find LCM,
LCM is 4
x=54+1⋅22⋅2
x=54+24
Add
x=74
Or,
x=134
Or,
x=1.75
X=1.75 IS YOUR ANSWER!
Hope this helps!
Have a great day: )

If we set the equation equal to 0, we can factor it to find its roots:
x² + 4x + 4 = 0
(x + 2)(x + 2) = 0
x = -2
This graph has one root, a double root, at -2. This means that a single point, which must be the vertex of the parabola, touches the x-axis at (-2, 0)
