Triangles ABC and AFD are congruent equilateral triangles. Find x and y.

x = 7, y = 27

Step-by-step explanation:

An equilateral triangle means all sides are equal, so you can say that

x + 4 = 2x - 3

Solve

4 = x - 3

7 = x

Because the triangles are equilateral, the angles must be 60 degrees.

2y + 6 = 60

Solve

2y = 54

y = 27

part a

x     y

0     8

1     7.5

2     7

3     6.5

4     6

5     5.5  

for every hour i deducted .5 inches from the length of the candle

part b

it is a function because for every x value there is only one y value

part   c

for every x value there is only one y value

x       y

0       8
