Find the perimeter of the triangle with vertices D(5, 6), E (10, 9), and F(7, 11). Do not round before calculating the perimeter. After calculating the perimeter, round your

answer to the nearest tenth.

The perimeter is

units.

step-by-step explanation:

step 1: solve one of the equations for one of the variables. let's solve the first equation for y:

step 2: substitute that equation into the other equation, and solve for x.

step 3: substitute x = 4 x = 4 x=4 into one of the original equations, and solve for y.

the cost of 6 show tickets is $30.

step-by-step explanation:

look closely at the graph, where it says 6 that's the amount of tickets. go up until you reach the dot. the dot shows that the coordinates are (6, 30). there fore from that you can infer that 6 show tickets cost $30.
