I and -2 is the solve for the equation
Answer:
I think the perimeter of the diagram is 5 and if you round it like
If it's 5 or greater, add 1 to the digit in the tenths place, and then remove all the digits to the right. (In the example above, the hundredths digit is a 4 , so you would get 51.0 .) To round a number to the nearest hundredth , look at the next place value to the right (the thousandths this time).
Correct answer:
"<span>D. As speed increases, height increases."
The x-axis is the one that indicates speed. The y-axis is the one that indicates height. As points of the represented line on the graph get bigger as to their x coordinate, they also get bigger on their y cordinate. When x increases, y increases also. This shows that their is a proportional relation between both the speed and height.</span>
3x²–243=0 —> 3 (x²–81) = 0 —>
x²–81=0 —> (x-9)(x+9)=0
x-9=0 —> x=9
x+9=0 —> x=–9
I hope I helped you^_^
