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
Answer:
30% of 210 is 63
Step-by-step explanation:
Well this is pretty easy, look. First we divide 3/4 (Length of shadow), then we multiply that by 36 (4*9 = 36), then we get 27 as an answer! Hope this helped. Brainliest is always appreciated.
Answer:
JM = 10
Step-by-step explanation:
Because MN║JL,
=
2(5) = 1(2x + 4)
10 = 2x + 4
2x = 6
x = 3
JM = 2x + 4 = 2(3) + 4 = 6 + 4 = 10
