How to solve systems by using tables
1 answer:
Answer:
There's a picture pf ratio tables below if you would like to view that.
Step-by-step explanation:
Let me explain this table to you. So in the first part. 1 group has 5 apples in it. Second group has ten. If you look the pattern you can tell that the groups are always multiplied by 5. 1 x 5 equals to 5. 2 x 5 equals 10. 4 x 5 equals 20 and so on. at the very end it's 135 times 5 equals 160. So there ya go for the ratio tables. I really hope this helps you. (times 5 is the ratio)

Answer:
Step-by-step explanation:
Notice that we are requested to perform three transformations in order: first a vertical compression (of the variable "y"), second a horizontal shift (affecting therefore the horizontal variable "x"), and lastly a vertical translation (affecting the variable "y")
1) Recall that a vertical compression by a factor 0.25 involves multiplying the full function y(x) by the factor 0.25:
2) the horizontal translation of 4 units to the right involves subtracting 4 from the variable "x":
3) the vertical translation 3 units up involves adding 3 to the full expression for "y":
