7>x>1
7 is greater than x, and x is greater than one
OR
1one is less than x, x is less than 7
The domains for this equation are (2,3,4,5) and the ranges for these equations are (1,2,1,3), so because there is no repetition for the x values, then k,-1 is a function. I say this because (2,1)= (-2,-1), (3,2)=(-3,-2), (4,1)=(-4,-1), and (5,3)=(-5,-3), so there is still no repeating x's. so, yes
6 slices 4 x2 = 8 and 3 x 2 = 6 so its 6 over and that is 6/8 of the pie
Since all the terms have the same base you just deal with the exponents.
(X^2)(x^7)=x^9
X^9(x^-3)=x^9/x^3=x^6
x - y = 14
given the ratio x : y = 5 : 3
then let x = 5x and y = 3x, hence equation can be expressed as
5x + 3x = 56
8x = 56 ( divide both sides by 8 )
x = 7
Hence x = 5 × 7 = 35 and y = 3 × 7 = 21
Thus x - y = 35 - 21 = 14
