Answer:
![y = 3x - 6](https://tex.z-dn.net/?f=y%20%3D%203x%20-%206)
Step-by-step explanation:
A linear function has the following format:
![y = ax + b](https://tex.z-dn.net/?f=y%20%3D%20ax%20%2B%20b)
In which a is the slope(rate of change) and b is the y-intercept, that is, the value of y when x = 0.
Rate of change of 3
This means that ![a = 3](https://tex.z-dn.net/?f=a%20%3D%203)
So
![y = 3x + b](https://tex.z-dn.net/?f=y%20%3D%203x%20%2B%20b)
A solution at (6, 12).
This means that when x = 6, y = 12. So
![y = 3x + b](https://tex.z-dn.net/?f=y%20%3D%203x%20%2B%20b)
![12 = 3*6 + b](https://tex.z-dn.net/?f=12%20%3D%203%2A6%20%2B%20b)
![b = -6](https://tex.z-dn.net/?f=b%20%3D%20-6)
The linear function is:
![y = 3x - 6](https://tex.z-dn.net/?f=y%20%3D%203x%20-%206)

i cant see figure g
Answer:
(2x + 3)(x + 5)
Step-by-step explanation:
2x² + 3x + 15 = 0
(2x + 3)(x + 5)
2x + 3 = 0
2x = -3
x = -3/2
x + 5 = 0
x = -5
It should be x < -10 because when you divide by a negative number the inequality sign flips.
