13 because you do 18-8 and you get 10 and divide that by 2 and you get 5 then add 5 to 8 and you get 13 and subtract 5 from 18 and you get 13 as well. Hope that helps

Since it's geometric, the ratio between the second and first term is equal to the ratio between the third and secons term.

So, x/18 = 8/x
x^2 = 144
So, x can be either 12, or -12

Constant of proportionality is 4

equation: x/y = 4

explanation:
let's take 20 and 5 for example, if you divide 20 by 5, you will 4 of course. that's the proportionality for the first one. if you continue to divide x value by y value you will get 4. for the last two you would divide 28 by 4 and multiply 8 by 4.

URGENT HELP!!!!!!!!!!!!!!!!!!!!!!!!!!!!

Nimfa-mama [501]

The mistake she made was timesing the 6 by the -7.5 as there is no x after the 6
Therefore:

-3.8(-7.5) +6
28.5+6 =34.5

Use the definition of logarithm to simplify each expression.

konstantin123 [22]

$1)\ \ \ log 10 ^{10}=x\ \ \ \Leftrightarrow\ \ \ 10^x=10^{10}\ \ \ \Leftrightarrow\ \ \ \ \ \ x=10\\\\2) \ \ \ log 10 ^{100}=x\ \ \ \Leftrightarrow\ \ \ 10^x=10^{100}\ \ \ \Leftrightarrow\ \ \ x=100\\ \\ 3)\ \ \ log 10 ^ {10-4}=x\ \ \ \Leftrightarrow\ \ \ 10^x=10^{10-4}\ \ \ \Leftrightarrow\ \ \ x=6$
