Answer:
Step-by-step explanation:
Let
x------> the number of shirts ordered
y-----> the total cost of the order
we know that
The linear equations that represent each situation are
<u>Shirts-2-Go</u>
------> equation A
<u> Shirts PLUS</u>
------> equation B
To know how many shirts to purchase so that the total cost is the same in both companies, equate equation A and equation B
Answer:
c) parabola and circle: 0, 1, 2, 3, 4 times
d) parabola and hyperbola: 1, 2, 3 times
Step-by-step explanation:
c. A parabola can miss a circle, be tangent to it in 1 or 2 places, intersect it 2 places and be tangent at a 3rd, or intersect in 4 places.
__
d. A parabola must intersect a hyperbola in at least one place, but cannot intersect in more than 3 places. If the parabola is tangent to the hyperbola, the number of intersections will be 2.
If the parabola or the hyperbola are "off-axis", then the number of intersections may be 0 or 4 as well. Those cases seem to be excluded in this problem statement.
