Maximum number of possible solutions x^2+4y^2=64 x+y=5

2

Step-by-step explanation:

We don't need to "solve" this to figure out the answer.

We need to recognize that the first equation given is that of an ellipse and the second equation given is that of a line.

A line and an ellipse in a coordinate system can have these outcomes:

1. They can intersect (touch) at 1 point

2. They can intersect at 2 points

3. Can't intersect at all

Thinking will make sense. So, the maximum number of possible solutions is 2.

Note: The number of points of intersection are the solutions as well

9 sandwiches per hour

step-by-step explanation:

when we have a rate, we want a 1 in the denominator

27/3 = 9

27 sandwiches/ 3 hours = 9 sandwiches/hour

the answer is 21%.
