math log PLEAseee helpp pretty please!!!
solve for first x 10^y=(x-2) x= 10^y +2 solve for the second x y-1=log(x+1) 10^(y-1)=x+1 or x= 10^(y-1) +1 the x=x, y=y 10^(y-1)+1=10^y +2 remember a^(b-c)= a^b/a^c so 10^y/10 + 1=10^y +2 10^y (-9/10)=1 or -9*10^y=10 log of each side -9 +y=1 y=10 so, now figure x.. x= 10^(y-1...

what would happen to your fractions if you changed them all to having a common denominator of 10 4/10 --- 6/10 1/10 --- 3/10 8/10 --- 10/10 or 1 7/10 or 1--- 9/10 13/10 or 1--- 5/10 did you notice that the numerator of the OUT is 2 less than the numerator of the IN ?

For Mattie - Math
2 X 10 square + 3 X 10 to the first + 5 X 10 to the zero +7 X 10 to the negative one in "math" = 2(10^2) + 3(10) + 5(10^0) + 7(10^-1) = 200 + 30 + 5 + 7/10 =235.7 looks like we have the number 235.7 decomposed into its different position values.

For n=1, 3^(n-1)/10 = 1/10 For n=2, 3^1/10 = 3/10 For n=3, 3^2/10 = 9/10 For n=4, 3^3/10 = 27/10 The ratio of successive terms is 3. I don't know why you wrote "bracket" at the end of your question.

Do a little investigation and you'll see the pattern 10^0 = 1 10^-1 = 1/10 = 0.1 10^-2 = 1/100 = 0.01 ... a billion is a thousand million = 10^3 * 10^6 = 10^9 I think you meant 10^5 -- that would be a 1 with 5 zeros = 10000

math
I assume 0 through 9 are allowed and repeats are possible. For example 000-0000 is allowed. How many prefixes? 10*10*10 = 1,000 how many digits 10*10*10*10 = 10,000 so 10^3 * 10^4 = 10^7 = 10 million I guess that is why they needed area codes.

"solve" means to find a value (or several values) of x which makes the equation true. a. f(x)=10 since f(x) = 3/(x+1), you have 3/(x+1) = 10 3 = 10(x+1) 3 = 10x+10 10x = -7 x = -7/10 So, if x = -7/10, f(x) = 10 Work the others the same way.

Yes, but "scientific notation" is often used when talking about powers of 10, like: 20000 = 2 * 10^4 This makes arithmetic with large numbers easy, since, following the rule above, all you have to do is add powers to multiply the factors of 10, like: (2.1 * 10^5) * (3 * 10^4...

think of 1/10 as a "unit." Then all you have to do is work with the numerators: 3-1+4 = 6 So, the answer is 6/10 But, that can be reduced to 3/5 You can think of factoring out the 1/10: (1/10)(3-1+4) = (1/10)(6) = 6/10 = 3/5

multiply the numbers and add the exponents. The answer has to be arranged so the number part is between 1 and 10. for example your number 3. (5*10^5)*(4.3*10^2) = 5 * 4.3 * 10^(5+2) = 21.5 * 10^7 but 21.5 = 2.15*10^1 so 2.15 * 10^1 * 10^7 = 2.15 * 10^8

Multiply both sides of the equation by (x+2) to get the x term out of the denominators. Then combine terms and use common denominators. (x/5) + (x-3) = (7/5)(x+2) = (7/5)x + 7/10 (12/10)x - 28/10 = (14/10)x + 7/10 (2/10)x = -35/10 2x = -35 x = -17 1/2
