Answer: You have to find the unit rate so you divide 7.50 by 3 which is 2.50 so for 1 pound it is 2.50, 2 pounds is 5, 3 pounds is 7.50, 4 pounds is 10, and 5 pounds is 12.50

Use the one line segment as flower stem and use the 8 rays as petals.
Answer:
fourth graph in second pic
Step-by-step explanation:
first lets substitute points to see whether the graph increases or decreases
sooo
y = -2(2^0)
y = -2
(0, -2)
y = -2(2^1)
y = -4
(1, -4)
y = -2(2^2)
y = -2(4)
y = -8
(2, -8)
with these points we can tell that the graph is decreasing, since there is two graphs decreasing, we can use the points to see if the parabola lies on the points (i think its called parabola)
its the last graph. fourth graph on page 2
Answer:
OPTION F
OPTION D
Step-by-step explanation:
Tom made his first mistake in Step 4, by subtracting 2.
After Step 3, he should have added 2 on both sides i.e.,
x = 4y - 2 should have become x + 2 = 4y - 2 + 2
⇒ x + 2 = 4y
So, in order to correct his mistake, he should add 2 on both the sides of the equation.
When
, you're left with
When
or
, you're left with
Adding the two equations together gives
, or
. Subtracting them gives
,
.
Now, you have
By just examining the leading and lagging (first and last) terms that would be obtained by expanding the right side, and matching these with the terms on the left side, you would see that
and
. These alone tell you that you must have
and
.
So the partial fraction decomposition is
