Answer:

The product of the y-coordinates of the solutions is equal to 3

Step-by-step explanation:

we have

x^{2}+4y^{2}=40 -----> equation A

x+2y=8 ------> equation B

Solve by graphing

Remember that the solutions of the system of equations are the intersection point both graphs

using a graphing tool

The solutions are the points (2,3) and (6,1)

see the attached figure

The y-coordinates of the solutions are 3 and 1

therefore

The product of the y-coordinates of the solutions is equal to

(3)(1)=3

Answer:

field goal points: 213

extra points: 125

Step-by-step explanation:

Given that a field goal is worth 3 points, then the total points made by field goals are: number of field goals * 3. In the case of Adam, that is: 71*3 = 213 points.

An extra point is worth 1 point, then 125 extra points are equivalent to 125 points.
