Answer:
Step-by-step explanation:
Possible options are A and B as the other two have no variables in their denominators and the numerators are of degree 1.
Now, option A, it has two different denominators involving the variable s. If you multiply all the terms by the product of the two 8s(s + 2), then you get a quadratic equation.
The option B. If you perform same operation, multiply all the terms by m(m + 1) this will result in degree 3 polynomial, which is a cubic equation but not the quadratic.
So the only option is A
Answer:
75%
Step-by-step explanation:
The percent increase is calculated as
percent increase = × 100%
increase = 7 - 4 = 3, thus
% increase = × 100% = = 75%
Y=mx+b
-1=5(-2)+b
-1=-10+b
9=b
the equation is
y=5x+9
Answer:
B

Answer:
The full question is attached in the picture below.
The better price for the battery is given with the 6 pack.
(£ 0.47 per battery)
Step-by-step explanation:
If 8 batteries cost £ 3.99
This means that one battery is equal to
£3.99/8 = £ 0.49875 ≈ £ 0.50 per battery
The pack of 6 batteries costs £ 2.79
This means that one battery is equal to
£2.79/6 = £ 0.465 ≈ £ 0.47 per battery
Then, we can conclude than the 6 pack gives us a better price per battery
