G because she need to sell 20 vases because the cost is 450 and if you divide it by 23 for the price the vases will be sold for it comes to 19.57 and you can't sell .57 of a vase you have to round up to make more than the money spent
3+2g=5g-9
5g-2g=3+9
3g=12
3g/3=12/3
g=4
1/2x + 3 = 2/3x + 1....multiply everything by the common denominator of 6
3x + 18 = 4x + 6
3x - 4x = 6 - 18
-x = - 12
x = 12 <====
multiplying by the common denominator will get rid of the fractions
Input of 3.....output of -6.......(3 * -2 = -6)
input of -2....output of 4........(-2 * -2 = 4)
input of 0....output of 0.........(0 * -2 = 0)
function rule : multiply the input by -2
Well this factor has to the answer b.) hope I helped.
