Answer:
k > 9/20
Step-by-step explanation:
If the parabola does not touch the x-axis, the discriminant is negative. That means ...
b^2 -4ac < 0
(-3)^2 -4(5)(k) < 0
9 < 20k . . . . . . . . . add 20k
k > 9/20 . . . . . . . . .divide by 20
An expo fn, such as y = e^x, has neither max nor min. The graph of y = e^x begins in Quadrant II and ends in Quadrant I; it has no upper limit. As x becomes smaller and smaller, the graph approaches, but does not touch, the x-axis.
FALSE
Unit price = total money / total weight:
2.50/2 = 1.25
Unit rate is 1.25 per 1 pound
The correct answer would be C.
Answer:
All that's necessary is to add 4 to both sides of the equation. This gives
... y = 1/2(x -8) +4
If you like, you can simplify this by eliminating the parentheses and collecting terms.
... y = 1/2·x -4 +4
... y = (1/2)x
Step-by-step explanation:
Answer:
For example, LCM(2,3) = 6 and LCM(6,10) = 30.
