Answer:
Rule 3
Step-by-step explanation:
The values correspond to the equation y=3^x
Each pound costs 2.40,
to check this 2.40 * 5 = 12
so 2.40 * 7 = 16.80
Answer: 16.80
Answer: 4x^2
Step-by-step explanation:
The formula is y-y0=m(x-x0)
So we plug in the Y's and the X's given:
-5-9=m(0-(-3)) >>>> -14=m(3)>>>>> m=-14/3
The next formula is y=mx+b , choose any point to use for X and Y: I'm gonna choose (0,-5)
-5=-14/3(0)+b >>> b=-5
Your formula is: y=-14/3x-5
