What is the solution of the system of equations? (y=-2x5) (y=-2x +20)

Step-by-step explanation:

(y=-2 * 5) (y=-2x+20)

-2*5=2x+20

-10=2x+20

20-10=2x

10=2x

x=5

there fore, y=-10

x=5

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
