Step-by-step explanation: Lets estimate first to the nearest whole number.
15.8 kilograms estimated is 16 kg
17.42 kilograms estimated is 17 kg
16.28 kilograms estimated is 16 kg
Now add the estimated values, 16 + 17 + 16 = 49 kg
The estimate gives you the correct answer because it gives you an accurate reasonable amount in this problem.
You can simplify the entire equation by dividing it all by 7, resulting in 7(b^2-6b+20).
Here, you can factor as you normally would. Your X values would have to be found using the quadratic formula.
Answer:
m = 0
Step-by-step explanation:
(0,-3) (2,1) is the two points we are going to use.
M=(1--3)/(2-0)=4/2=2
The slope is 2
