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: 308
Explanation: because 2 days is 48 hours so multiply by 4 will equal 192 the subtract it from 500 and the answer is 308
Answer:
Both ends go down
Step-by-step explanation:
If the degree is EVEN, both ends pint the same way. If it is ODD, they point in opposite directions. The negative sign means the equation is flipped over the x axis and both ends go down.
there are more cat per minute on the 2nd chart then the first you can see that the line on chart 2 goes closer to the line that says cat wile going up!
hope this help if so can i have brainliest!
Answer:
y = 9,25
Step-by-step explanation:
(5*0,3) + 2y = 20 (x=0,3)
1,5 + 2y = 20 . (-1,5)
2y = 18,5 ( /2)
y = 9,25
