Athermometer measures 56 degrees on monday and the true temperature is 65 degrees. the temperature is measured with the same thermometer for the next 5 days and it is 9 degrees less than the true temperature each time. what is this an example of?

Hello!

This is an example of a linear function. Whatever x-value you plug in for the temperature, you would subtract 9, giving you the f(x), or y.

f(x)= x-9

I hope this helps!

step-by-step explanation:

given perimeter: 28cm

length: 9cm

atp,

2(l+w)=p of the reactangle

2(9+x)=28

18+2x=28

2x=28-18

x=10/2

x=5

therefore width is 5 cm

x = -3

y = -18

step-by-step explanation:

to solve by substitution, substitute one variable and solve for the other. then substitute again to find the remaining variable.

x-1/3(3x-9) = -3 since y=3x-9 substittute y.

x-1/3(3x-9)=-3

x + x +3 = -3

2x+3=-3

2x+3-3= -3-3

2x=-6

x=-3

substitute again into y=3x-9

y=3(-3)-9

y=-9-9

y=-18
