Answer:
Tha awnser is B.
Step-by-step explanation:
I'm guessing this is a slope problem, so the equation would be like this: y = mx + b where m is the slope and b is the y-intercept.
Using this,
Which is equal to,
Answer:
£100.98
Step-by-step explanation:
Step 1: find total price of tickets
Total price of tickets = 6 adults (£12) + 3 child (£6) = 6(12) + 3(6)
= 72 + 18
Total of tickets = £90
Step 2: Find the extra added 10% booking fee
Booking fee added = 10% of £90
= 10/100 × 90
= 0.1 × 90
Adding booking fee = £9
Step 3: Calculate the added 2% that would be added for using credit card
Cheryl would be paying £99 with her credit card (price of tickets + added booking fee = £90 + £9)
2% of £99 = 2/100 × 99
Added credit card charges = 0.02 × 99 = £1.98
Step 4: Calculate the total charge to be paid by Cheryl if she uses her credit card for the payment
Total charge = cost of tickets + added booking fee + credit card charges
= £90 + £9 + £1.98
= <em>£100.98</em>
Answer:
domain: all real numbers
range: y ≥ -5
Step-by-step explanation:
The domain of any polynomial function is "all real numbers."
This polynomial is of even degree and has a positive leading coefficient. It will have a minimum value, but no maximum. We can get an idea of the minimum value by looking at the vertex form.
f(x) = x^4 -2x^2 -4
f(x) = (x^4 -2x^2 +1) -5 = (x^2 -1)^2 -5
The squared term will have a minimum value of 0, so the minimum of f(x) is -5.
The range is all real numbers greater than or equal to -5.
