How many solutions does the system have? \begin{cases} 3y =- 6x+9 y =-6x+9 \end{cases} ⎩ ⎪ ⎪ ⎨ ⎪ ⎪ ⎧ 3y=−6x+9 y=−6x+9

exactly one solution

Step-by-step explanation:

hope this helps :)

a² + b²= c²

24² + 7² = c²

c= 25

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

1       7.6

2       7.2

3       6.8
