Solve the equation for 1 and 5:
1^2 +4 = 1+4 = 5
5^2 + 4 = 25 +4 = 29
Find the difference:
29 -5 = 24
Find the difference of the X values: 5-1 = 4
Rate of change is the change in Y over the change in X:
The rate of change would be: 24/4 = 6
Answer:
From top to bottom:
3
7
6
12
Step-by-step explanation:
You just simply add the number in the top row and the number in the column together.
2 + 1 = 3
4 + 3 = 7
2 + 4 = 6
6 + 6 = 12
Standard form: 8x - y = -2
A star is written to show multiplication. It is a replacement for a dot or a x which is what you probably learned to be the "times" sign. In upper level maths, the "x" is replaced with a " * " to make it more legible and to avoid confusion with the variable "x".
