Solve for x. -2x-3=-7

Mathematics

Answer:

x = 2

Step-by-step explanation:

The whole goal when solving problems like this is to get the x alone. So the first step would be to get the -3 over to the other side. To do this, you would add 3 to each side of the equation, so that the -3 on the left side cancels out.

-2x - 3 = -7

+3          +3

-2x = -4

The next thing you need to do is divide each side by -2. You would do this because right now, the equation reads "negative two times x equals negative four". When you divide a multiplication problem, it cancels out, so you are left with just the x.

-2x = -4

÷ -2    ÷ -2

x = 2

You now have the value of x.

Please let me know if you need any more help. I hope this explanation helps you understand a bit better. Have a great day! :)

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}
