A student draws a triangle to scale using side lengths 8, 16, and 18. Can the student conclude that this is a right triangle?

This triangle is not a right triangle

Explanation:

To find this you can use the set up for the pythagorean theorem. The hypotenuse is the c while the other sides are a and b.

After setting it up you add in the numbers

Then square them

Then you add the two sides together

If they are equal then it is a right triangle. While if they are not equal it is either obtuse or acute.

Sorry if this is long or doesn't make sense.

step-by-step explanation:

total income = price of one ticket   *   number of tickets sold

  y                 =     4                                   x

so the equation is y=4x     with x≥0   because number of tickets sold can not be negative

thus the equation is a semi -line with an end point at

(0,0)

passing through :

x=1     y=4(1) = 4   so through (1,4)
