10 yards/5 minutes = (10 x 3) feets/(5/60) hours = 30feets/0.0833 hours = 360 feet per hour.
Answer:
the student in question bought 3 large notebooks and 3 small notebooks
Step-by-step explanation:
the easiest way to explain how to do this is by recognizing that the student bought $54 worth of notebooks- which is not divisible by 10 easily. that means, we should subtract 8 from 54 until we get a number that IS divisible
54 - 8 = 46 (one small notebook)
46 - 8 = 38 (two small notebooks)
3 8 - 8 = 30 (three small notebooks)
then, divide 30 by 10 to see how many large notebook the student bought.
30/10 = 3

-6/3 division sign 2/-9
To solve: multiply by reciprocal inverse
-6/3 x -9/2= 54/6 or 9
Answer:
Step-by-step explanation:
y = x^2 - x - 2 is a quadratic function. It's easily factorable: y = (x + 1)(x - 2). Setting this result equal to zero yields the x-intercepts: -1 and 2. This matches the x-intercepts shown on the graph.
The axis of symmetry, x = -b/(2a), derived from the coefficients 1, -1 and -2 of this particular function, is x = 1/2. This x = 1/2 is also the x-coordinate of the vertex. To find the y-coordinate of the vertex, we evaluate y = x^2 - x - 2 at x = 1/2, obtaining:
y = (1/2)^2 - (1/2) - 2, or y = 1/4 - 1/2 - 2, or -2 1/4. This does not quite agree with the y value (-2) shown in the diagram, but is close.
Answer:
I didn't know some answers but I wrote the majority of them below!
Step-by-step explanation:
Symmetry of axis: (4, 0)
Vertex: (4, -3)
Domain: 14? (I'm not positive on this one! so sorry)
Range: 14
Min/Max: (4, -3)
I have no clue on the next one!
x-intercepts: (.5, 0) (7.5, 0)
y-intercept: (0, 1)
Then I don't know the last two... I'm sorry I couldn't help you out fully!
