Answer:
(Missing part of the question is attached)

Estimates are too large.
Step-by-step explanation:
Suppose the only information we know about the function is:

where the graph of its derivative is shown in the attachment
<h3>(a)</h3>
If the function
is differentiable at point
, the tangent line to the graph of
at 1 is given by the equation:

So we call the linear function:

We know the
as it is given in the question, and
from the graph attached. Substitute in the equation of
.

<h3>(b)</h3>
At x=1,
is positive but it is decreasing. However. if we draw the tangent lines, we see that the tangent lines are becoming less steeper, so the tangent lines lie above the curve
. Thus, The estimates are too large.
Answer: 30 $15 tickets and 20 $35 tickets
Step-by-step explanation:
.X%2BY=50
2.15X%2B35Y=1150
From eq. 1,
15X%2B15Y=750
Subtract from eq. 2,
15X%2B35Y-15X-15Y=1150-750
20Y=400
Y=20
Then,
X%2B20=50
X=30
