we know that

If two lines are parallel, then their slopes are the same

m1=m2

and the y-intercept is unequal

If two lines are perpendicular, then the product of their slopes is equal to -1

m1*m2=-1  or m1=-1/m2

therefore

<u>the answer is</u>

Two non vertical lines have slopes m1 and m2​, respectively. The lines are parallel if​ m1=m2 and the ​y-intercept are​ unequal; the lines are perpendicular if​ m1*m2=-1 or​ m1=-1/m2.

There is no imaginary part in real number

Example of real number is 5

A wildfire is spreading at an alarming rate. The wildfire begins at a size of 8 square feet. It then doubles its width every x h
Mrac [35]

Answer:

D.

14000=8\times 2^{x+y}

Step-by-step explanation:

The wildfire begins at a size of 8 square feet

It means that initial area =8

It then doubles its width every x hours,

and doubles its length every y hours

so, we can set up equation

A(x,y)=8(2)^x\times (2)^y

now, we can simplify it

A(x,y)=8(2)^{x+y}

we are given

After a period of time, the wildfire covers 14,000 square feet

so, we can set A(x,y)=14000

we get

14000=8(2)^{x+y}

14000=8\times 2^{x+y}
