25 miles per hour
Step-by-step explanation:
100 / 4 = 25
Answer:
1 5/11 ≈ 1.455
Step-by-step explanation:
The total number of vehicles owned is
(4×0 + 8×1 + 6×2 + 4×3) = 32
The total number of families is ...
4 + 8 + 6 + 4 = 22
Then the mean number of vehicles per family is ...
32/22 = 16/11 ≈ 1.455
Answer:
x = -5
Step-by-step explanation:
We can use the below formula to find the line of symmetry.
( x - a )² + b
Here,
line of symmetry = +a
Vertex = +b
And now let us take a look at the given equation.
y = x² + 10x + 22
To find the line of symmetry from the given equation we have to make the given equation as the given formula.
Let us use the completing square method for that.
y = x² + 10x + 22
<em>Put zero instead of y.</em>
x² + 10x + 22 = 0
x² + 10x = -22
x² + 10x + 25 = -22 + 25
( x + 5 )² = 3
( x + 5 )² -3 = 0
Therefore,
line of symmetry of the line is = -5
∴ x = -5
