Answer: x=-1
Step-by-step explanation:
the x value of the vertex = -b/2a if the equation is in "ax^2+bx+c" for
you are in luck
x value of the vertex = -4/4 = -1
the line of symmetry is a vertical line, and since it must pass through the vertex
line of symmetry: x=-1
its wrong
Step-by-step explanation:
The correct answer here would be D. And that is because, in a triangle, the sum of 2 of the sides has to be greater than the third side for all sides. If we add 22 and 13 we get 35, and 35 is greater than 9, for sure. But if we add 13 and 9 we get 22 which is not greater than the third side length of 22; it would be collinear with the side length and it has to be greater than the side length.
Answer:
The Price of Home last time it was sold is $2,000,00
Step-by-step explanation:
Given as ,
The current price of Home = $220,000
∵ This current price is 10% increase in the last price
Now , Let the last price be = $ x
Again AS per question ,
x + 10% of x = $220,000
x + × x = $220,000
() × x = $220,000
Or, x = ()
I.e x = $200000
Hence the Price of Home last time it was sold is $2,000,00 Answer
