Answer: <u>It's in the photo.</u>

Step-by-step explanation:

<u>1.</u> 7^8 divided by 7^8 would be 1.

<u>2.</u> 2^-2 would be 0.25. 2^-3 would be 0.125. Multiplied together would be 0.03125.

3. 5^-10 is 1.024e-7

. 5^-15 is 4.096e-9. Simplified would be 0.4.

<u>4.</u> 4^2 is 16. 4^-1 is 0.25. Multiplied together would be 4.

How do you do this equation: 9|5x+8|=54
Sergio [31]

Answer (2 answers):

x = -2/5,  x = -14/5

Step-by-step explanation:

First step is to try and get the absolute value by itself on one side and everything else that's not inside the absolute value on the other side.

9|5x+8|=54

|5x+8| = 54/9

|5x+8| = 6

Remember how absolute values turn everything positive? For example

|-4|=4, but |4|=4 as well. So we must do the same to our problem by splitting up the absolute equation into two parts.

|5x+8| = 6     and     |-(5x+8)| = 6

now solve the first equation.

(Just remove the absolute value sign and solve it normally)

5x+8 = 6

5x = -2

x = -2/5

Now solve the other equation

-(5x+8) = 6

-5x - 8 = 6

-5x = 14

x = -14/5

Can someone explain the properties and help me with this work?
Sever21 [200]
The first property is commutative  ( the numbers 38 and 677 are  swapped over)



Then we have the associative property ( where the paretheses are moved to get 38 and -38 together)

then the additive inverse ( 38 + (-38) = 0

and finally to get the 677 we use the additive identity property.
