What shoul I do to answer 10 raised to -2 ?

For negative exponents, make a fraction of 1 over whatever the base number is.  Then raise the denominator to the positive of your exponent.\n\nIn this case 10^(-2) would be 1/10^2 (read "1 over ten squared) so the answer is 1/100\n\nSome other examples:\n\n2^-5 = 1/(2^5)\n\n4^(-1/2) = 1/(4^1/2) or 1/sqrt4

you can get x lower, because it can be all real numbers.  However, your answer is correct, because if you put a negative number in for x, you get a positive answer.  So the range is y is greater than or equal to -3.

To get N by itself,\n\nsubtract 5 from both sides of the equal sign.\n\nand multiply by 2 on both sides of the equal sign.\n\nI'm not telling you the answer...someone else might, but I won't.\n\nps: it's not 1!!\n\nThe answer really isn't important here. What is important is knowing how to get the answer.\n\nEDIT:\n\nJUST CURIOUS, WHAT THE HECK IS UP WITH THE THUMBS DOWN ON MY ANSWER AND THE ONE BELOW ME?\n\nWAS THAT THE FIRST PERSON THAT ANSWERED REALIZING WHAT AN IDIOT THEY WERE, AND DELETING THEIR QUESTION?\n\nI JUST DON'T UNDERSTAND PEOPLE SOMETIMES.

let me solve ur example first, then i will explain it to u.\n-5-(-15)\n-5+15\n10 is the answer. \n\nIf there r two negative together, make it positive.\nUse the following formula:\n- -= +\n- += -\n+ += +\n+ -= -

Change 1/2 to a decimal and add it to 11.\n\nChange 1/5 to a decimal and add it to 2.\n\nSubtract the second decimal number from the first.

10-x= -5\n10-x-10= -5-10\n-x = -15\n-(-x) = -(-15)\nx=15

Order of operations: Parentheses Exponent Multiplication Division Addition Subtraction.\n\n2 - 2[4-9] ÷ (-5)\n2 - 2[-5] ÷ (-5)\n2 - [-10] ÷ (-5)  ~~ same as 2 + 10 ÷ (-5)\n2 + [-2]  ~~ same as 2 -2\n= 0\n\nI'd double check that if I were you; it's a bit early for me. :*)

About -37.21\n\nYou want the two terms to be 10 apart...Upon inspection you know t MUST be negative, since the second term can not be greater than the first term.\n\nSo if the two are equal t = -36.55, so through trial and error I got -37.21

Multiply a negative times a negative and you will get a postive answer.

the answer is 8.\nfinding the slope:\ny2-y1/x2-x1\nsub\n9-5/x-10 = -2\n4/x-10 = -2\nthe value that gives you -2 after dividing would be 8.

slope is 2,  y intercept is  - 10

I think the simplest way to solve this is to move the decimal place over one to the left.   If for example they wanted 1% you would move it over two to the left.  If they wanted .01% three to the left.  If they wanted .001% four to the left.  You get the point. \n\nSo 10%= $2500

x^2-9x-10=0\n\nx^2 +(-1 +10)x -10=0\n\nx^2 -x +10x -10=0\nx(x-1) +10(x-1)=0\n\n(x+10)(x-1)=0\nthus x=10 , -1

Just multiply the numbers.  positives will get a positive answer.  Odd number of negatives will get a negative answer.  Even number of negatives will get a positive answer.

I just plugged this into my calculator.\n\n[1, 0, 2, 0, 2, 0 | 0\n0, 1, -3, 0, -2, 0 | 0\n0, 0, 0, 1, -1, 0 | 0\n0, 0, 0, 0, 0, 1 | 0\n0, 0, 0, 0, 0, 0 | 1 ]\n\nTake it however you want.
