To solve such problems we need to know about the Linear function.

<h2 /><h2>Given to us</h2>

A.)  y – 2 = –5(x – 2)

B.)  x + 7 = –4(x + 8)

C.)  y – 3 = y(x + 4)

D.)  y + 9 = x(x – 1)

<h2>Linear function</h2>

A linear function is a function that is in the form of y=mx+c. thus we will check which functions are in this form, to know that a function is linear or not.

A.)  y – 2 = –5(x – 2)

y-2=-5(x-2)\\y-2= -5x+10\\y = -5x+10+2\\y = -5x+12

As we can that the function is in the form of y=mx+c. therefore, the function is a linear function.

B.)  x + 7 = –4(x + 8)

x+7 = -4(x+8)\\x+7 = -4x-32\\4x + x = -32-7\\5x = -39

As we can that the function is not in the form of y=mx+c. therefore, the function is a non-linear function.

C.)  y – 3 = y(x + 4)

y-3=y(x+4)\\y-3=yx+4y\\

As we can that the function is not in the form of y=mx+c. therefore, the function is a non-linear function.

D.) y + 9 = x(x – 1)

y+9 = x(x-1)\\y+9 = x^2 -x\\

As we can that the function is not in the form of y=mx+c. therefore, the function is a non-linear function.

daser333 [38]

We have been given a table of overnight low temperature for a four-day period. We are supposed to give a possible temperature for Wednesday.

We are told that the low temperature on Wednesday was between the second and third highest temperature.  

Let us place our given temperatures from least to greatest order.

Sunday (-11), Thursday (-8), Friday (7), Sunday (18)

We can see that second and third highest temperatures are -8 and 7 respectively.  

Any number between -8 and 7 will be a possible temperature for Wednesday. 3 can be a possible temperature for Wednesday as 3 is between -8 and 7.
