If the sides of a triangle mnp are mn= 4x+9, np= x+5, mp= 7x-20, find the range of possible values for x. show steps!

Step-by-step explanation:

The sides MN, NP and MP of the triangle MNP should satisfy inequalities:

Then

Simplify this system:

Thus, the range of possible values for x is

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

step-by-step explanation:

1/8 3/16 3/4

step-by-step explanation:

you put them as all the same denominator and multiply
