Answer:
(-5,8)
Step-by-step explanation:
The left number represents the x-axis, the right one the y-axis. A translation to the right means in the positive direction on the x-axis, which is why we add 3 to -8 which gives us -5. Down on the y-axis is in the negative direction, which means we have to subtract 1 from 9, giving us 8.
Answer:
what are the given values for x?
Step-by-step explanation:
i don't know what the given values for x are
but if you know them, here's an example
let's say x=4
y=(4)+2
y=6
It is y = 12x + 20.
You start with 20 as the y-intercept because that is the starting amount that you paid. The constant rate of change is 12 dollars per book. So, 12 time however many books written as 12x. Hope that helps! :)
168 divided by 5.6 equals 30 hope this helps
