Answer:4
Step-by-step explanation:
y = (2x-4)/3
to find the inverse change x and y then solve for y
x = (2y-4)/3
mutiply by 3 on each side
3x = 2y-4
add 4 to each side
3x+4 =2y
divide by 2
(3x+4)/2=y
h^-1 (x) = (3x+4)/2
Choice C
x-3y=7 2x-6y=12
You can multiply -2 in the first equation like this.
x+6y=7
2x-6y=12
Now you can eliminate 6y and -6y so cross them out and do x-2 which is -1 and 7-12 which is -5 -1/-5 would be .2

<span>A ratio is the number of one object of interest compared to the number of another object of interest that can be displayed using a fractrion. In this case you're looking for number of fiction books vs. the nunber of overall books read and that fraction is 25/30 that can be simplified to 5/6 or for every 6 books she reads 5 are fiction</span>
