Answer:

14 children went to the movies and 18 went to the pool.

14 niños en el grupo del cine y 18 en el grupo de la piscina.

Step-by-step explanation:

We can solve this question using a system of equations.

I am going to say that:

x is the number of children that went to the movies.

y is the number of children that went to the pool.

Class of 32:

This means that $x + y = 32$

To go to the pool, it costs 2.5 euros. To go the movies, it costs 3.5 euros. 94 euros were spent.

This means that $3.5x + 2.5y = 94$

From the first equation:

$y = 32 - x$

Replacing in the second

$3.5x + 2.5y = 94$

$3.5x + 2.5(32 - x) = 94$

$3.5x + 80 - 2.5x = 94$

$x = 14$

$y = 32 - x = 32 - 14 = 18$

14 children went to the movies and 18 went to the pool.

Cosine rule: a^2 = b^2 + c^2 - 2bc cos A
-> a^2 > b^2 + c^2 - 2bca

Find the slope of the line on the graph.

Rasek [7]

The slope should be -1/2, because the line goes down 1 unit and then right 2 units.

Also it would be y = -1/2x+1 in y=mx+b.
