Between which two ordered pairs does the graph of f(x) =
x2 + x - 9 cross the negative x-axis?
Quadratic formula: x = =
(-6, 0) and (-5,0)
(4.0) and (-3,0)
(-3,0) and (-2, 0)
(-2, 0) and (-1,0)

step-by-step explanation:

no, her answer is not correct.   we square the lengths of all sides and then determine whether the pythagorean theorem holds here:

9² + 15² = 306.   this is not equal to the square of the longest side ( that square being 395.   answer c is correct.

i believe it is 0.1m because the measurement of 30.4m limits how precise you can be

you can only be as precise as the least precise measurement

a) is $10.34

b) is 6 toppings

let me know if this is right lol.

step-by-step explanation:

in order to solve by completing the square, what number should be added to both sides of the equation?

88

how many of the solutions to the equation are positive?

0

what is the approximate value of the greatest solution to the equation, rounded to the nearest hundredth

3.03
